• permanent NAS-mount in Ubuntu - wrong fs type, bad option, bad superblock

  - by Emil

  My network drive shows up in the file browser, just like my external usb-harddrive. Moving, running and editing files works. Hovering over it shows smb://lacie-2big/nasdisk . BUT, when I want to save a file, the drive doesn't come up as an option. All I can see is my other places, including my usb-harddrive. I am a complete newbie but I am GUESSING that it has something to do with the mount not being a "real" mount but just a shortcut to the smb location. So I ran the tutorial at https://wiki.ubuntu.com/MountWindowsSharesPermanently about how to "mount a network drive permanently". edited my fstab to //LaCie-2big/nasdisk /media/nasmount cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0 and running sudo mount -a gave me the following error: mount: wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program) In some cases useful info is found in syslog - try dmesg | tail or so Now thats a very helpful error message, BUT, before I go any further, I'd be really thankful if one of you could tell me if I'm even in the right ballpark, or if my actual need: to be able to download files (ie torrents) directly to the drive, can be possible as it is already. Question: How to fix "wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program" when running mount -a

• Changes to grub in ubuntu 10

  - by jdege

  I've been running CentOS 5 for some years. I've decided to upgrade to Ubuntu, and with 10.04 just out, this seemed like a good time. I'm a tad paranoid, so I started off with a new set of drives - one to install on, one to backup to, and one as a spare. I removed my existing CentOS 5 drives, and did an install, and had no problems. I installed the server version, and used the default full-disk LVM installation. Next, I copies my backup scripts over, edited them to work with the new configuration, and did a test backup. That worked fine, as well. Then comes the real test, could I do an install of the backup onto the spare drive? (I won't put anything of importance on a system that doesn't have a reliable backup, and if I've never done a restore, it's not reliable.) I booted from a System Rescue CD (ver 1.5.3), with the spare drive as /dev/sda, and the backup drive as /dev/sdb. I had no trouble in partitioning, configuring LVM, formatting, making swap, or restoring the file systems. But when I got to restoring grub to the MBR, I ran into problems. My restore instructions from CentOS 5 said run grub, then enter two commands: root (hd0,0) setup (hd0) The first command exits with an error: "Checking if /boot/grub/stage1 exists ... no" I did some googling around, and found that the Grub2 included in recent Ubuntus is very different than the Grub 0.97 included in CentOS 5. One site suggested I use: grub-install --root-dir=/mnt/restore /dev/sda That appeared to work, but when I booted from the drive, I ended up at a grub prompt. Any ideas as to what I need to do? It seems like a simple problem, but my attempts at searching out answers on the web are being swamped by references to the old version of Grub. Help would be appreciated.

• Linux Tuning for High Traffic JBoss Server with LDAP Binds

  - by Levi Stanley

  I'm configuring a high traffic Linux server (RedHat) and running into a limit I haven't been able to track down. I need to be able to handle sustained 300 requests per second throughput using Nginx and JBoss. The point of this server is to run checks on a user's account when that user signs in. Each request goes through Nginx to JBoss (specifically Torquebox with JBoss A7 with a Sinatra app) and then makes an LDAP request to bind that user and retrieve several attributes. It is during the bind that these errors occur. I'm able to reproduce this going directly to JBoss, so that rules out Nginx at least. I get a variety of error messages, though oddly JBoss stopped writing to the log file recently. It used to report errors about creating native threads. Now I just see "java.net.SocketException: Connection reset" and "org.apache.http.conn.HttpHostConnectException: Connection to http://my.awesome.server:8080 refused" as responses in jmeter. To the best of my knowledge, I have plenty of available file handles, processes, sockets, and ports, yet the issue persists. Unfortunately, I have very little experience tuning servers. I've found a couple useful documents - Ipsysctl tutorial 1.0.4 and Linux Tuning - but those documents are a bit over my head (and just entering the the configuration described in Linux Tuning doesn't fix my issue. Here are the configuration changes I've tried (webproxy is the user that runs Nginx and JBoss): /etc/security/limits.conf webproxy soft nofile 65536 webproxy hard nofile 65536 webproxy soft nproc 65536 webproxy hard nproc 65536 root soft nofile 65536 root hard nofile 65536 root soft nproc 65536 root hard nofile 65536 First attempt /etc/sysctl.conf sysctl net.core.somaxconn = 8192 sysctl net.ipv4.ip_local_port_range = 32768 65535 sysctl net.ipv4.tcp_fin_timeout = 15 sysctl net.ipv4.tcp_keepalive_time = 1800 sysctl net.ipv4.tcp_keepalive_intvl = 35 sysctl net.ipv4.tcp_tw_recycle = 1 sysctl net.ipv4.tcp_tw_reuse = 1 Second attempt /etc/sysctl.conf net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 net.core.netdev_max_backlog = 30000 net.ipv4.tcp_congestion_control=htcp net.ipv4.tcp_mtu_probing=1 Any ideas what might be happening here? Or better yet, are there some good documentation resources designed for beginners?

• Removing forward lookup zone broke our site - why?

  - by user102469

  I'm fairly new to the job and trying to get to grips with the infrastructure here. We've moved a site from being locally hosted on our own network to an external host (1&1). I've transferred the DNS hosting from the previous DNS host to 1&1 to keep things simple. Once everything had gone through, visitors that were external to our network were being directed to the new site on 1&1 but requests from within our network were still going to our own server. I noticed in the DNS server that there was a forward lookup zone for the site pointing to our own server still. My (admittedly simplistic) understanding was that pausing that zone would then cause the DNS server to get the address for the site from our external DNS servers and our users would start landing on our new site. However, what happened instead was that they were being met with "page not found" type errors. I've resolved it my modifying the forward lookup zone A record to point to the external web server but would like to get an understanding as to why pausing the zone didn't work. Would deleting the zone work? I am reluctant to try that as creating it again will not be as easy as simply pressing "start". Many thanks.

• In spite of correct DNS, Exchange sending to wrong destination server for single outbound domain

  - by beporter

  My company uses an SBS 2003 server and makes use of Exchange to host our own email. We also have a linux server hosting domains for some of our clients. In order for us to send to those clients, we had internal DNS set up to shadow the client domains to provide "correct" MX records inside our network. For example, public DNS for a domain abc.com might point to 1.2.3.4, but internally we have MX records set up to route mail for abc.com to 172.16.0.4, which is the linux email server. This setup was entirely functional; this is just back story. We've recently moved one of our client domains from our internal linux server to an external email provider. When we did that, we naturally deleted our internal shadow DNS records so our Exchange server would fetch correct (public) DNS records and route mail out to the new external host. This has NOT had any effect on Exchange though. Even after rebooting the Exchange server and completely flushing the DNS cache (nslookups on the Exchange machine itself correctly resolve to the new external address) Exchange still attempts to deliver messages for the domain to our internal server! Exchange correctly routes to all other internal and external domains when sending email. Somehow Exchange is trying to deliver to a machine that by all accounts it has no business trying to use for just this one domain. Is there a DNS cache that Exchange uses internally? Is there a way to flush that internal cache? What else could I be missing?

• Break all hardlinks within a folder

  - by Georges Dupéron

  I have a folder which contains a certain number of files which have hard links (in the same folder or somewhere else), and I want to de-hardlink these files, so they become independant, and changes to their contents won't affect any other file (their link count becomes 1). Below, I give a solution which basically copies each hard link to another location, then move it back in place. However this method seems rather crude and error-prone, so I'd like to know if there is some command which will de-hardlink a file for me. Crude answer : Find files which have hard links (Edit: To also find sockets, etc. that have hardlinks, use find -not -type d -links +1) : find -type f -links +1 A crude method to de-hardlink a file (copy it to another location, and move it back) : Edit: As Celada said, it's best to do a cp -p below, to avoid loosing timestamps and permissions. Edit: Create a temporary directory and copy to a file under it, instead of overwriting a temp file, it minimizes the risk to overwrite some data, though the mv command is still risky (thanks @Tobu). # This is unhardlink.sh set -e for i in "$@"; do temp="$(mktemp -d ./hardlnk-XXXXXXXX)" [ -e "$temp" ] && cp -ip "$i" "$temp/tempcopy" && mv "$temp/tempcopy" "$i" && rmdir "$temp" done So, to un-hardlink all hard links (Edit: changed -type f to -not -type d, see above) : find -not -type d -links +1 -print0 | xargs -0 unhardlink.sh

• Coffee spilled and went inside CPU...computer not starting

  - by Harpreet

  Today coffee got spilled over my table, and some of it (very less) reached the CPU placed under the table. I think little bit of it got inside the CPU through the front face of the CPU. As that happened the fan started running very fast and made noise. I tried to restart to see if it becomes fine, but the computer didn't start again. First it gave an error of "Alert! Air temperature sensor not detected" and didn't start. Next I tried again multiple times of starting the computer but then it gave some memory error. I was not able to start the computer. Incase there's a problem in hard disk or something related to memory, is there any way we can extract our work or data? I am scared if I am not able to extract my work in case some problem occurs like that. What options would I have? Help! EDIT: I have attached the photo here and you can see the area spilt in red circle. The hard drive electronics have been affected and internal speaker may also have been affected. Any advise on cleaning and if hard drive can work? EDIT 2: Are there any professional services offered to extract data from blemished hard disk, like this one, in case I am not able to run it personally?

• SATA Windows 7 Problems

  - by Isaacs

  Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit. Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives. Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..). Oddly enough if I boot to a ubuntu everything works fine. Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!

• During Vista Repair - No operating system is listed.

  - by Jack Marchetti

  After a Windows update, my brother's Gateway computer loads to the "Step 3 of 3: 0%" and reboots. Safe Mode does not work. I placed a Vista DVD in the drive, and re-booted. (Note, this is my Vista DVD, not the Recovery/System disc that would come with a computer. Gateway does not give you CD's anymore. I believe they store recovery on a partition, but that partition has been wiped out). I chose "Repair Your Computer" I get a dialog box, but no operating system is listed. I'm then prompted to "Load Drivers". What drivers am I supposed to be loading here and where from? I placed a CD in the drive to "load drivers" but I don't see my DVD drive listed. All I saw where X:/Sources along with several Removable Media slots that were empty. On another screen I tried Startup Repair, which didn't do anything. I attempted to use System Restore - but it doesn't detect the hard drive. I'm guessing that I'm missing some sort of SATA driver and that is why the hard disk is not being found. Any ideas on this?

• Converting An Older VMWare Image to ESXi

  - by Bart Silverstrim

  I have just installed VMWare ESXi and imported one physical machine without issue and one virtual machine, from an older version of VMWare Server on a Linux system, to it without issue. But I have another machine (Windows XP), virtual running on the VMWare Server, that I can't get the Converter to work with. Converter runs, says everything is fine, but when I go to the ESXi VSphere manager and hit the button to power up that vm, the console stays black with a blinking cursor and the processor for that VM spikes 100% and stays there. An event log item in VSphere warns something about activation issues with Windows. Has anyone else run into this issue before? Is it something with the disk controller? I copied the folder with the VM directly to the storage drive on ESXi hoping to create a new machine and point the data store to that folder or at least that drive image; nope, something about not using an IDE controller (must be something with the older format). In short, converter is doing something that particular machine doesn't like, and I can't find a way to simply open that hard disk image or convert it unless someone else has seen this. I try attaching a bootable CD image for disk repair to see if it can check the hard drive but I can't seem to get the console to boot from it...either too slow on the button or it just isn't able to easily boot from a virtual drive image (.iso). Any suggestions or help?

• SSD seems dead after wakeup from Windows Sleep, BIOS stalls but doesn't find it anymore

  - by Abel

  The morning, the following scary scenario happened: I woke up my Windows system Typed in my username and got an error (something like "could not load security xxx", but unsure of exact wording) System auto-restarted after cliking OK It didn't boot up anymore to the SSD with Windows 7 OS (I have another disk I can boot to, but that doesn't see the disk either). Obviously, this happened right after I instantiated a backup procedure, which hasn't succeeded either. The BIOS can't find the drive when I connect to SATA. And it can't find the drive when I connect it to SAS. I have a Dell Workstation T7400, most recent BIOS (version A06), version of SAS Host Bus Adapter BIOS (HBA) is MPTBIOS 6.14.10.00 (2007.09.29) from LSI Logic Corp. Other findings: When connecting to SATA, the DELL Logo screen stays really long (5 minutes) and then at the end of POST it says that a drive is not found When connecting to SAS, the SAS HBA initializing phase takes long (2 minutes, against normally 15 seconds) When running Dell Diagnostics, it doesn't finish and gives the error Exception occurred in module MPCACHE.MDM file "IOAPICSP.ASM" line 1645. I contacted Dell. On their advice I tried different slots and different cables to no avail. I use an APIC battery power, spikes in the power are thus unlikely. My conclusion so far: the disk is dead. I need this disk very badly because it contains the last few days of important development of which not all code was checked in the moment this happened. Are there any ways to recover dead SSD drives? The drive is a new X25-M G2 160GB model SSDSA2M160G2GC 2.5" in an extension bay and has been running without issues for 3 months on SAS.

• What do the readonly attributes in diskpart really mean?

  - by marzipan

  I am wondering exactly what the meaning is of the "Read-only" disk and volume attributes that you can twiddle in diskpart on Windows 7. I am trying to set up an external USB drive as an installation medium for my own software, so I'd like to protect it against casual or inadvertent changes by users who it is given to, so they don't screw up the installation files they might need in the future. From what I can tell by experimentation with diskpart, the volume read-only attribute is actually stored on the physical disk somewhere, because I can set it and it shows up when I take the drive to another machine. This is great because my users can't (easily) change any of the files on the volume, or format it from Windows explorer. However, the disk read-only attribute seems to be just an aspect of how the current machine is accessing the drive. When I set it I can no longer delete the volume in the disk via Disk Management, but when I take the drive to another machine, the attribute is no longer set and in Disk Management I can delete the volume on the disk. I guess I'm not that worried about my users doing that, but I am annoyed that I don't understand what these attributes are really doing. Another thing that I don't understand is that the "volume" read-only attribute actually seems to be global to the disk - if I have two volumes on the disk, and I set the readonly flag on one of them, then it gets set on the other one too. ?!? I have the feeling I'm not searching for the right docs - all I'm finding is diskpart docs that give the syntax for twiddling these attributes, not what they really mean. Any pointers would be very welcome! Thanks, Asa

• running chkdsk /F on a large mounted NTFS image file gets BSOD (Windows Vista)

  - by Citizentools

  Using ddrescue, I've created ISO files from the C: and D: drives on my Windows XP laptop's harddisk (after the laptop stopped booting and chkdsk etc. wouldn't fix it). I was able to mount the 60 GB D.iso file use OSFmount, and successfully recreated the D: drive on another laptop. The C.iso image is more problematic. ddrescue left about 3mb unrecovered of 85 GB total, after multiple passes (no big worries about this) and I'm able to mount it with OSFmount on a Windows Vista laptop. However, when I run chkdsk /F /V on the mounted drive (which was mounted as H:), I consistently get a blue screen (BSOD). CHKDSK makes it through the first three passes, including index fixing and security descriptor fixes, without errors, but triggers a BSOD when it attempts to fix the volume records or bitmap If I attempt to fix the drive by clicking on Properties-Tools-Error checking-Check Now-Automatically fix file system errors, I get an alert box reading "WIndows was unable to complete the disk check." I'd try a tool other than OSFMount, but it's the only thing I've found so far that will mount large ISO files, and it has worked for me up to now in this process. [Update 2011-11-13 18:41 EST] Just ran the same process using the original Windows XP laptop, with a different internal drive, and chkdsk worked like a champ. So the question is still interesting, but decidedly less urgent.

• How to figure out what VirtualBox did?

  - by AndrejaKo

  I'm trying to boot a custom made-in-ASM OS on my recent laptop. The OS is intended to be installed on a floppy and during make creates a bootable floppy. Since I don't have a floppy drive, I installed it on a virtual floppy. After that I used WinToFlash's create bootable MS-DOS USB drive option to transfer the floppy image to an USB flash drive. Then I tried to boot my computer from it but got only a repeating broken string on screen. After all that I made a virtual hard disk image form the flash drive using this tutorial and tried to boot a virtual machine from it. First time I got same problem as on real computer. I then used the reset option and next time and every time after that OS booted correctly. My question is: How do I figure out what exactly happened to the virtual machine between first and second boot? UPDATE I just created a new VM with default settings for windows XP and it has the same problem that I have on a real computer. I was unable to reproduce the procedure which made the first VM work correctly.

• Hiding subfolders from users with Windows Server security

  - by Frans

  Using Windows Server 2008. I would like to allow all users to map to a common network drive and be able to browse it. But, I only want them to be able to see the subfolders they actually have access rights to. Is this doable? Example I have a share with two folders on it; \\domain\share\FolderA \\domain\share\FolderB With three different security groups, I would like to map a network drive for all three to \\domain\share. However, for group1, I want them to only be able to see FolderA, group2 should only see FolderB and group3 should see both. I am not just talking about denying access to the actual folder, which is easy enough, I don't want the user to even be able to see that the folder exists. In other words, when group 1 logs in and do "dir n:\" they should see N:\FolderA When group 2 logs in, they should see N:\FolderB and when group 3 logs in they should see N:\Folder A N:\Folder B My half-baked solution If I completely block access to the root then I can't map a drive to it. I can give everyone the traverse right which then allows the user to map a drive. However, if a member of group1 or group2 tries to go to "N:\" they get an access denied error. If they go to N:\FolderA (for group1) then it works. So, that sort of works, but it would be nicer if the user could actually browse to N:\ and just only see the subfolders they have access to. I am pretty sure I have seen this done but not sure how to do it myself. Any advice would be greatly appreciated.

• Can somebody please recommend a good local file backup utility that will be Windows & OSX Compatible?

  - by JAG2007

  I have an external hard drive that I keep all of my work files on and transfer them back and forth between my Windows 7 box at work, and my Mac at home (I work from home frequently). Can someone recommend a really good backup utility that I can use on that external drive, to back the files up to my work computer locally, or the other external drive on my machine at work? I'm looking for preferably a free or open source software, and I'd prefer it to be cross system compatible, although I would also consider using a software that will only work on the Windows box. Also, I will consider a software that has a price assuming it is a really good piece of software and the price is reasonable (like under $50 or so). I checked out CrashPlan a bit, but not sure if that's gonna be really what I'm looking for. To reiterate I'm not looking for online backup solutions, just a piece of software that can back up my data to another drive locally. CrashPlan Free seems to offer this, but not sure how good it is (considering their goal is to get me to buy a pay for version). *NOTE: I'm running Windows 7 in 64bit so I need a piece of software that will be compatible with 64bit OS. My previous software, PC Backup, is not. That's partly why I'm in this boat.

• New SSD, is the MBR broken? DISK BOOT FAILURE

  - by Shevek

  I've been running Windows 7 on a WD 500gb SATA single drive, single partition setup for some time with no issues. I've just installed a new Kingston V Series 64gb SSD and performed a clean install of Win7 to it, deleting the partitions on the 500gb and using that as a data drive. All was well for a few reboots but then I started to get "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" messages. If I put the Win7 install DVD back in the drive it boots fine. Tried a clean install again, after replacing SATA cables and swapping SATA ports, with a complete partition wipe of both drives. Again, rebooted fine a few times then back with the "DISK BOOT FAILURE" error. Looked on the web and found some discussions about it so I then started from scratch again. This time I wiped the MBR on both drives using MBRWork, disconnected the 500gb and reinstalled to the SSD. Removed the install DVD and installed all the drivers which involved many reboots, all with no problem. To make sure I also did a few cold boots as well. Reconnected the 500gb, initialised, partitioned and formatted it. Copied data to it and did some more reboots and shutdowns. All was ok. Then out of the blue comes another "DISK BOOT FAILURE" and again, if the Win7 install DVD is in the drive it boots fine. So, is the SSD a bad'un? TIA UPDATE: It was a BIOS issue! I found a hidden away option for HDD boot order, which was separate from the usual HDD/CDRom/FDD boot order option. The WD was set to boot before the SSD... Swapped them round and all is well. Still don't understand how it worked at first though... Thanks Solaris

• pxe boot dos 7.x / 8.x on modern mainboard without floppy controller

  - by GitaarLAB

  How to pxe boot MS DOS 7.x / 8.x on a modern pc (mainboard without floppy controller) without using an external usb floppy drive? MS DOS 6.22 and earlier or other flavors pxe boot just fine on floppy-less hardware. But DOS 7.x and 8.x renders an error on boot: "Type the name of the Command Interpreter (e.g., C:\WINDOWS\COMMAND.COM) I read somewhere during research this was a rather unknown error, that started to become more common due to the advent of floppy-controller-less hardware. On some hardware (bios dependent) one could plug a usb-floppy-drive in the computer before booting (but that MIGHT also require it to be a "golden floppy drive" (as they where called back then). From a russian site (I read about a year ago and cannot find the hyperlink) MS-Dos versions 6.22 did some-kind of floppy-drive reset during initialization and since it couldn't connect to the floppy-host thus the error. How can I resolve this (without a physical external usb floppy)? Might there be some kind of virtual floppy-driver that could resolve this (for example to be loaded before the dos image loads)? Or could someone point me into the right direction (maybe even a hex-address and some further explanation or something)? I'm using syslinux by the way.

• How can I take a one time full backup of a Windows Server without the need for a restore program?

  - by TheCleaner

  I have a Windows SBS server with about 500GB of data that I'm decommissioning but I'd like to take a final backup of the server and place it on an external USB drive. I already have multiple backups of the server on disk from the past but they are through Simpana Commvault. I'd like a backup that will simply copy the file structure, ACLs, timestamps, etc. as is to a NTFS volume on the external drive. This way if someone says "I need x file on the server you decommed" I can search the external drive real quick instead of firing up Commvault, cataloging, restore, etc. I know the built-in Windows backup is great, I just don't feel like running it for a restore job on this. I'd like an option where in the future it won't require a program to run a restore. Rather a simple mount of the drive will suffice. I believe I can use robocopy just fine, but I'm not sure if it will grab the Windows directory, system files, and full user profiles correctly even with the /ZB option. Options? Is Robocopy /E /ZB /COPYALL /DCOPY:DAT /MT:32 /R:5 /W:5 /LOG:copylog.log the way to go here?

• Converting software RAID1 to RAID10 for /boot

  - by luckytaxi

  Array info: /dev/md0 - /dev/sda1 and /dev/sdb1 /dev/md2 - /dev/sda2 and /dev/sdb2 Partition info: /boot - /dev/md0 / - /dev/md1 I have two drives that are setup as RAID1 using software RAID on Redhat. I added two additional drives (same size) and I would like to conver the RAID1 to a RAID10. The problem I'm having is adding the last drive to the array. I've gotten as far as creating a RAID10 with two missing devices but as soon as I add the last drive, all hell breaks loose. It seems /dev/sda1 is the culprit. What I'm not too sure about is how to create the RAID10. I've tried the following mdadm --create /dev/md2 --level=raid10 --raid-device=4 /dev/sdc1 missing /dev/sdd1 missing I then proceeded to fail /dev/sdb1 from /dev/md0 and added that partition to /dev/md2. I proceeded to install the MBR on EACH partition since boot resides on /dev/sdx1 on each drive. As a test, all is well, I'm able to boot back into the system once I do a quick reboot. Now, when I go add the last drive /dev/sda1, it breaks. I attempted to install grub on /dev/sda1 and I get the following ... grub> root (hd0,0) /dev/sda root (hd0,0) /dev/sda Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0) setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type At this point, the array is hosed I believe. I rebooted the server and it refuses to boot.

• Apache runs in console but not as a service?

  - by danspants

  I have an apache 2.2 server running Django. We have a network drive T: which we need constant access to within our Django app. When running Apache as a service, we cannot access this drive, as far as any django code is concerned the drive does not exist. If I add... <Directory "t:/"> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> to the httpd.conf file the service no longer runs, but I can start apache as a console and it works fine, Django can find the network drive and all is well. Why is there a difference between the console and the service? Should there be a difference? I have the service using my own log on so in theory it should have the same access as I do. I'm keen to keep it running as a service as it's far less obtrusive when I'm working on the server (unless there's a way to hide the console?). Any help would be most appreciated.

• Setting Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from newly mounted drives

  - by galacticninja

  How do I set Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from external hard drives and TrueCrypt-mounted volumes? I remember in Windows XP, I can set a percentage of total disk space that will automatically be used as storage capacity for deleted files by the Recycle Bin, and this will be applied to all external HDs or TC-mounted volumes. Windows 7 defaults to the 'Don't move files to the Recycle Bin. Remove files immediately when deleted' setting for newly mounted external HDs and TC mounted volumes. Since I am expecting deleted files to go to the Recycle Bin, sometimes this causes an 'Oops' when I delete files in external hard drives or TC mounted volumes, as Windows does not move deleted files to the Recycle Bin, but just deletes the files permanently. I have to remember to manually set a custom Recycle Bin storage space for each new drive that is mounted by Windows to avoid this issue. I only use and mount TrueCrypt file containers, not drives. I also don't mount TrueCrypt file containers as removable drives. ('Mount volume as removable medium' is unchecked in Mount Options.) In my $Recycle.Bin > Properties > Security settings, 'System' and 'Administrators' are already set to 'Full Control', while 'Users' only have 'Special Permissions' checked in gray. There are no other groups. I haven't changed or edited anything in these settings. I am using Windows 7 Ultimate.

• Computer always freezing after random periods of time. No errors listed.

  - by Wesley

  Hi, all. Here are my specs beforehand: AMD Athlon XP 2400+ @ 2.00 GHz, 160GB IDE HDD, 128MB GeForce 6200 AGP, 2 x 512MB PC3200 DDR RAM, CoolMax 350W PSU, 1 x CD-RW Drive, 1 x DVD-ROM Drive, FIC AM37 Mobo, Windows XP Pro SP3 My desktop freezes after random periods of time but there are no errors listed in the Event Viewer after a forced shutdown and restart. A couple months ago, I found that when it froze, the floppy was being accessed at the same time. So, I disconnected the floppy (since I never used it anyways) from the power supply and motherboard. Everything was working fine and the computer never froze. This past Christmas break, I left for a Conference and when I got home, the computer kept freezing again. So, this time, I just disconnected the DVD reader (from mobo and power) and started it up. Still, it froze almost right away. Then I found some older sticks of RAM (2 x 256MB PC2100 DDR) and swapped them in. Everything worked fine again after that. I even swapped the 2 x 512MB PC3200 DDR RAM back in and everything worked okay. Then it started freezing again, and I tried all possible RAM combos, still freezing within 5-10 minutes of startup. One thing I've realized is that the floppy drive is still listed in My Computer and I uninstalled it from my Device Manager already. There were no software errors, and I uninstalled the most recent software, with no effect. Still, I have no idea what is wrong because everything ran fine before that. Any suggestions? EDIT: Still have yet to buy some blank CD media to use Memtest86+. However, would a lack of virtual memory cause the computer to freeze? EDIT2: So after a long time, I ran Memtest86+ and all is well. Turns out though, after removing my original DVD reader and replacing it with a DVD-ROM drive, there is no freezing whatsoever! Thanks for all your suggestions!

• Dell XPS 1530 DVD-RW firmware problem

  - by josecortesp

  Hello everyone. I have this XPS laptop since a year and a half ago. About 2 months ago, with the waranty expired, i tried to run the optiarc slot load DVD-RW firmware update, and said everything was okay. Then I restarted it and the problem started: Now, every single time I turn on my computer, it get stuck at the BIOS POST until the drive sounds like "ready" and then the computer starts normally. And this happen EXACTLY the same when it's getting back from sleep. I'm pretty sure is not a software issue, because I tried with Vista Home Premiun 32 bits, Ubuntu (from 8.10+)32 & 64, and with W7 64. Already tried to run the firmware installer like a million time, in case it is a failing install with no luck. Also, google it to see if someone has the same problem, and again, no. The Drive performs pretty okay once the System is on, but waiting to the drive to be ready everytime is really annoying. The Firmware I updated was this, and the drive is: K937C Assembly, Dvd+/-rw, 8, SLOT, 1530 Sony Nec Optiarc Inc. I'll apreciate any help you can give me

• Why is the Windows 8 recycle bin using more space than it is allocated?

  - by oldmankit

  I ran WinDirStat to scan the contents of my hard drive. I was surprised to see that the $RECYCLE.BIN folder on my D: drive takes 26 GB of space. I emptied the recycle bin, refreshed the folder in WinDirStat, but it still takes 26 GB of space. I reduced the Maximum size of the recycle bin for this drive to 10000 MB for the main user of this computer, and disabled the recycle bin for the other user, and refreshed the folder in WinDirStat, but it still takes 26 GB of space. I ran (in an elevated window) rd /s D:\$Recycle.bin, and refreshed the folder in WinDirStat, and finally it became empty. Why was it taking up space even after I emptied it? Why was it taking more space (26 GB) than the maximum allowed amount (10 GB)? Update: After six months of using Windows (no re-install and no changes of settings related to the Recycle Bin) I used WinDirStat to check how big D:\$RECYCLE.BIN has become. It is now 29 GB. In Recycle Bin Properties, I select drive D, and it is still a custom maximum size (10000 MB).
