• CoreStore Encryption Error on Mac Lion

  - by Michael

  I am trying to encrypt an external drive using diskutil CoreStorage on Mac Lion 10.7.4. I thought the only requirements were that the drive have GUID partition scheme and Journaled HFS+ file system. I think my drive is configured accordingly but when I type the following command I get an error message back: Michaels-MacBook-Pro:~ Michael$ diskutil cs convert disk2 -passphrase TestPassword Error converting disk to CoreStorage: The given file system is not supported on Core Storage (-69756) Here are the details reported for the drive in question: Michaels-MacBook-Pro:~ Michael$ diskutil list disk2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Test1 499.8 GB disk2s2 Michaels-MacBook-Pro:~ Michael$ diskutil list disk2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Test1 499.8 GB disk2s2 Michaels-MacBook-Pro:~ Michael$ diskutil info disk2s2 Device Identifier: disk2s2 Device Node: /dev/disk2s2 Part of Whole: disk2 Device / Media Name: Test1 Volume Name: Test1 Escaped with Unicode: Test1 Mounted: Yes Mount Point: /Volumes/Test1 Escaped with Unicode: /Volumes/Test1 File System Personality: Journaled HFS+ Type (Bundle): hfs Name (User Visible): Mac OS Extended (Journaled) Journal: Journal size 40960 KB at offset 0xe8e000 Owners: Disabled Partition Type: Apple_HFS OS Can Be Installed: Yes Media Type: Generic Protocol: FireWire SMART Status: Not Supported Volume UUID: 1024D0B8-1C45-3057-B040-AE5C3841DABF Total Size: 499.8 GB (499763888128 Bytes) (exactly 976101344 512-Byte-Blocks) Volume Free Space: 499.3 GB (499315826688 Bytes) (exactly 975226224 512-Byte-Blocks) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: No Ejectable: Yes Whole: No Internal: No I'm a little concerned that the "Partition Type: Apple_HFS" entry is causing the problem, but I don't know how to change that.

• Iverter, inverter cable, or a display cable?

  - by krebshack

  I was recently hired at a small repair shop. I work indoors while my boss does on site calls for small businesses. I have to troubleshoot and fix laptop screens a few times a week and this is why I'm posting this question. I'm having trouble figuring out how to stream line the troubleshooting process. For example, how do I determine whether the inverter is broken while also determining that the inverter cable is not. How can I quickly decide that the inverter cable is broken while knowing that the inverter is most likely not broke. Or how do I know that it's just the display cable? It seems like this is a good way to approach things: "It could be the inverter, backlight, or the LCD panel itself. Backlight failure is usually hinted at by a pink hue to everything. Inverter failure usually results in the dimming of images on the screen to the point where the backlight is not even on (the inverter provides power to the backlight)" Source. While remembering that things "like flickering, screen freeze in dark image and [a] corner starts to get brighter" point to a "failure in the LCD panel itself, though it could just as easily be a loose data cable connected to the back of the LCD." Source. In short, I'm soliciting advice that anyone might have on how to quickly make the best decision about what's causing problems with laptops display. Thank you.

• Ubuntu Hardy : Testing for environment variables in udev rules doesn't seem to work

  - by Fred

  I have a Ubuntu 8.04 LTS (server edition), and I need to write a udev rule for it to act upon plugging a USB thumb drive. However, I need a different action depending on the filesystem of the drive. I know I can use the ID_FS_TYPE environment variable to check for the filesystem on the drive. Following instructions found here, I try a dummy udev rule as such : KERNEL!="sd[a-z][0-9]", GOTO="my_udev_rule_end" ACTION=="add", RUN+="/usr/bin/touch /tmp/test_udev_%E{ID_FS_TYPE}" ACTION=="add", ENV{ID_FS_TYPE}=="vfat", RUN+="/usr/bin/touch /tmp/test_udev_it_works" LABEL="my_udev_rule_end" However, when I plug in a thumb drive with a vfat filesystem (which should trigger both rules), I end up with a file called /tmp/test_udev_vfat, meaning the first rule was triggered successfully, and that the ID_FS_TYPE environment variable is "vfat", but I don't have the other file, meaning that although I know the ID_FS_TYPE env variable is "vfat", I can't seem to check against it for a match. I tried googling the thing, but pretty much every result seems to assume ENV{ID_FS_TYPE}=="vfat" works. I also tested the exact same udev rule on Ubuntu 10.04 LTS server, and I have the same result. I'm probably missing something very simple, but I just don't get it. Does anyone see what is wrong with my udev rule that would prevent it from matching on ENV{ID_FS_TYPE}? Thanks.

• Is there a way to know what the Windows Disk Cleanup utility will delete?

  - by Cam Jackson

  When I run the Disk Cleanup utility that's built into Windows 8, it tells me that it can free up 53GB by deleting 'Temporary Files'. However, a CCleaner analysis on default settings only finds about 300MB worth of space to free up, so I'm wondering what Disk Cleanup has found that CCleaner does not. Note that this question appears to be similar to what I'm asking, but the accepted answer says that 'Temporary Files' refers to %TEMP%. I've already cleared out most of C:\Users\Cam\AppData\Local\Temp, and it now has only 230MB of stuff in it, even with system files showing. So where is this 53GB located? Is there a way to find out what it is? Edit: I should note that this is on a 110GB SSD, so it's almost half the drive. And in fact I'm only using 86GB, so if it's really going to clear out 53GB, that would be more than 60% of the stuff on my C drive. I'm starting to think that Disk Cleanup caches its analysis, and hasn't updated since I started cleaning up the drive earlier today. Although when I run it it says that it's 'Calculating' how much space can be saved, and it takes about 5-10 seconds to do so. Hmmm... Edit2: Here is what my hard drive looks like, according to SpaceMonger (Right click-Open image in new tab, so you can see it properly): You can see why I was starting to think that the 53GB figure is actually wrong. Even if 'Temporary Files' includes my hiberfil and everything in WinSxS (about 13GB total), that would be 26GB, which is only halfway there. Hard to see where there's 53GB of stuff to delete.

• Issues with creating USB bootable Mountain Lion

  - by Sidd

  I am trying to set up a triple boot Windows 8, Mountain Lion, and Ubuntu. I am stuck though. I have got Windows 8 on a partition, and I am trying to get Mountain Lion on there at this point. I installed a VMware with a Snow Leopard 10.6.2 image on the Windows 8 platform. I used the disk utility in this program in order to get Mountain Lion on there. This is what i did specifically: I got the installesd.dmg. I 'mounted' that file or whatever you call it, and out came something along the lines of "Install Mountain Lion OS x" (something like that - it was like a submenu under the installesd.dmg in the disk utility). I got my PNY 8 gb Attache Flash Drive and went to the Erase tab of disk utility. I erased it using the Mac OS Extended (Journaled) setting and called it "Mac". I went to the Restore tab, dragged "Mac" into destination, and dragged "Install Mountain Lion OS x" to the source. Everything seemed to go well, but it didn't. When trying to boot from the flash drive (and yes, I set the BIOS correctly), it skipped it, and loaded Windows 8 normally as if nothing was plugged in. When I try looking at the flash drive in windows 8, it comes up as a 200 mb capacity drive labeled "EFI" with nothing in it (remember, it was 8gb in the beginning). I downloaded Plop Boot Manager, but it did not recognize a USB being plugged in. Does anyone know how I could fix this?

• VMware vSphere Hypervisor 5 with Intel SPL 5000 in Raid 0 no boot from DVD?

  - by Richard

  I hope this is the correct StackExchange, since I am only using StackOverflow for Web development, but need some help with my server configuration. I would like to install VMware vSphere Hypervisor 5 on my server here at home and run a view machines on it such as Windows Server 2008 and Red Hat. I used to have either OpenSuse or Windows Server 2008 installed but I would like to get into VMWare Hypervisor. My hardware configuration: - Intel S5000PSL with bios version S5000.86B.10.60.0091 build date 10/09/2008 as of read out of bios - E5420 @ 2.5GHz Intel Xeon CPU The Intel Virtualization Technology is enabled in the BIOS - DVD DH20A4P DVD Writer - 8GB ECC Ram I have configured a RAID 0 on my 2 WD 2TB SATA drives I have burned the Hypervisor 5 on an empty DVD and it is bootable, I tested it on my client PC. The main problem here is basically, that I cannot boot the DVD on my server. I have set the Boot Option to the DVD drive. I have booted from the BIOS straight in the DVD drive and it does not work. I do not see any error messages. The only thing I see are the PXE error messages when it tries booting from the network and other devices, obviously without any result. Does anybody know why I cannot boot the DVD? What could cause the problem? I have sucessfully installed Windows Server 2008 via original DVD about 1 year ago, so the DVD drive can read and does work. The DVD drive is available in the BIOS and I have checked all cables and none of them is loose in any way. I even see the light flashing but it does not want to boot from the DVD. I am looking forward to suggestions and things that I should check. Thank you very much

• SSH hangs without password prompt

• New Computer freezing up at random

  - by Benjamin Frost

  Since I built my system about 4 weeks ago I'v been getting random freezes, Sometimes it can happen directly after startup and sometimes it wont freeze up for 3-4 days of 24/7 running. It seems to be happening under all stress loads but mainly when the CPU is under 10% load. It doesn't give me a BSOD or anything, it simply just freezes and repeats the last sound before the freeze until I shut it down by the power button. I'v re-seated everything in the system except the CPU, Cleaned the RAM sockets and gold fittings. None of the components have been clocked above their factory settings as of yet, don't want to overclock them until I sort out these freezes. Temps are all well under the rated max temps, the highest the temps have been are below CPU: Low load: 16-21°C Full Load (100%) 40-43°C *(From HWMonitor by CPUID) GPU 1: Low Load: 25-30°C Full Load (100%): 45-50°C GPU 2: Low Load: 23-27°C Full Load (100%): 45-50°C *(GPU Temps from Catalyst Control Center) General Case temps Rear: 18-20°C Mid: 20-21°C Front (HDD/SSD Bays): 14-19°C (Case temps may be a little off as it's from the Kaze master pro fan controller) I have Un-installed EVERY driver for Motherboard, GPU & Soundcard and Re-installed twice.

• Migrating Windows XP BOOT.INI Settings to Windows 7 Boot-loader

  - by Synetech inc.

  Hi, Two months ago my motherboard died, so I bought a used computer that came with Windows 7. I have since installed my old hard-drive, which had Windows XP on it, in this system. What I am trying to do now is to figure out a way to migrate the settings from XP's BOOT.INI into 7's boot-loader. Below is the BOOT.INI I used in XP (I have reduced the strings and updated the disks to point to the new location of the old HD. Oh and I am not clear on the drive letters. In XP, I could boot the recovery console or MS-DOS from a file in C:\ that contains the boot-sector. I am not sure what drive letter it would be called now—I had to manually change all the drive letters of the old partitions in Windows 7 because it auto-assigned them all wrong/differently). [boot loader] timeout=10 default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP (Safe)" /safeboot:network /sos /bootlog /noguiboot C:\CMDCONS\BOOTSECT.DAT="Recovery Console" /cmdcons C:\BOOTSECT.DOS="MS-DOS 7.10" /win95 I have looked around, and have only been able to find some bcdedit commands to add XP to the boot-loader, but none that include information on setting safe-mode for it (or changing any of the XP load options for that matter). Not surprisingly I suppose, I have not found anything on adding the XP recovery console or DOS to the Windows 7 boot-loader. (Yes, I tried EasyBCD, but that did not help; it had no options for XP, and the best I managed was to get a choice of booting 7 or normal-mode XP—choosing XP didn't even give the old XP boot menu.) Can anyone please tell me how to export the entries in XP's boot.ini to 7's boot-loader so that on boot, I can choose to load the following: Windows 7 Windows 7 (Safe-mode) (Windows 7 (The Win7 counterpart of the Recovery Console)) Windows XP Windows XP (Safe-mode) Windows XP (Recovery Console) MS-DOS 7.10

• How do I resolve BSOD: PAGE_FAULT_IN_NONPAGED_AREA?

  - by Burnzy

  I have been trouble shooting this for a few days and cannot fix this anyhow. Computer specifications Mobo: ASUS Sabertooth X58 LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: Intel(R) Core(TM) i7 CPU 920 (Bloomfield) @ 2.67 ( no OC ) RAM: 6144MB RAM GPU: 2x NVIDIA GeForce GTS 250 1Go in SLI (sli is not enabled anyway at the moment anyway) Drives: OCZ RevoDrive OCZSSDPX-1RVD0120 PCI-E x4 120GB PCI Express MLC Internal SSD [RAID-0]. (I know this could potentilly cause trouble but I had the BSOD before using this drive) Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive - Bare Drive Click here for a log of a crash I just had. Click here for a log of a crash I had 30 minutes later, note that it's another driver. Some info Occurence: It seems pretty random so far, haven't noticed any kind of pattern I tried: Windows memory diagnostic (went smoothly at 1066mhz) As I said, it was still happening on my HDD, so when I bought the revodrive I install a new OS on there and still got the error, I believed it happened and I had no drivers installed at that point (not 100% sure) Change the following registry value to 1 (true): HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager \MemoryManagement\ClearPageFileAtShutdown Tried to lower even more ram clock Made sure ram timing was set to recommended by manufacturer Verified if motherboard was in good physical condition (yes and its brand new) There is one thing to note, when I got the new motherboard, I installed the new drivers WITHOUT formatting and the I removed the motherboard drivers that I could remove from the control panel (pretty much the first things that have been installed). Could this cause an issue even ON THE OTHER drive (revodrive). Hopefully someone can help me, I am getting tired of this, spending so much money and cannot get this to work correctly. If you need any other information let me know, thank you!

• hdparm - how to secure erase SATA SSD over USB

  - by cc0

  I have been following this guide on how to secure erase an SSD (trying to improve the performance of mine, which currently only writes at about 30mb/s seq). However, I'm using an USB--Sata docking device to avoid having the harddrive frozen. Apparently using this solution the SATA device is recognized as a SCSI drive, which is giving me trouble. I use the "hdparm -I /dev/sda" command with those parameters, and I get the error; HDIO_DRIVE_CMD (identify) failed: Invalid Exchange After a lot of googling on the issue I can't seem to find anyone who has actually solved this problem. However, I have not tried to just go ahead and use the secure erase. So I'm not sure if this would actually still work. I would love any and all input I can get on this, especially on whether it will still work to do a secure erase with the drive being recognized as a SCSI drive. The drive itself is a Samsung 256gb SSD (pm800), I'm sure you can understand my reluctance to go through this procedure without feeling reasonably safe that I won't mess it up beyond repair.

• Where is my free space?

  - by Andrey

  A week ago I got a low disk space warning on my Vista x64 Ultimate box - 60 Mb free on the disk C; I cleaned up some downloaded msdn images and got 20 Gb freed up. Three days ago I got another notification, it looked suspicious but I didnt have time to deal with it and just moved some heavy stuff to another drive to free up about 17 Gb.... Today morning - 53Mb left on drive C, again! Now it looks really suspecious, so I downloaded TreeSize to see what's taking up the space, just to see it reporting only 121 GB out of 200 GB used, in other words I suppose to have about 79 Gb free. Then I went to Folder Options, enabled viewing of system and hidden files, rerun teh tool to see another 5 Gb added (which is expected). Then I open disk C in windows explorer, select all and right click Properties, to see it reporting teh same amount of files - 126 Gb. But when I look at Drive C properties, it reports that 200GB of 200 Gb are taken. I just scanned the drive with two different antiviruses - Symantec and AVG and found no viruses... I'm a little confused at this point, any ideas where is my free space, woudl be highly appreciated! Thank you! Andrey

• How to check DVD region settings in Window 7

  - by jmatthias

  I have installed Windows 7 on my laptop. When I put a movie in the DVD drive, the video player starts up and tells me 'THIS DISC IS NOT FORMATTED TO PLAY IN THIS REGION'. I have changed the DVD region a few times in the past but while I was in Windows XP I changed the region in Region 1. I cannot find how to check the DVD region setting in Windows 7 (it's not located on the hard properties page of the DVD anymore. Does anybody know how to check the DVD region in Windows 7? Update: If I connect an external USB DVD drive I can see the DVD region tab on the hardware properties dialog. I guess there is some compatibility problem with my internal DVD drive and Windows 7 (as I said I was able to inspect/change the DVD region in Windows XP). Solution: I think I had used LtnRPC in the past to remove the region from my DVD drive. It looks like Windows 7 does not like region free DVD drives (at least mine anyway). I was able to use LtnRPC to reset the region back to 1. I can now see the region tab on the DVD drives hardware properties.

• Two instances of Windows Vista on boot up after failed clean install

  - by Dwayne

  I tried to install a clean version of Vista but failed. I ended up with Windows and Windows.old on my C: drive and a dual boot option on boot up. I gave up and booted up the old version and tried to rename the Windows.old to Windows and was asked if I wanted to merge the two folders. I answered yes and all seemed OK until I booted up this morning and was given the choice of two versions of Vista. The first one is the one that failed to installed correctly and the second one is the old version. How can I get rid of the failed installation? I got rid of the bad boot via MSCONFIG. Here is my current situation: several hard drives installed Using C: as my boot drive a much larger drive (H:) for storing most of my files. I found a subfolder in my C:\windows folder named windows. Upon inspection I determined it to be older than the C:\windows folder and therefore it must be the older, working version of the boot. I renamed the C:\windows folder to c:\windows.bad and moved the sub windows to the C: root directory. I also copied it to the h: drive. Now MSCONFIG reports that the copy that is booting is the h: copy. How can I change it back to the C:\ copy and can I delete the C:\windows.bad file set?

• Windows won't sleep after booting from grub

  - by mkasberg

  I recently added a second hard drive to my computer and I am using it do dual-boot Linux (Ubuntu 12.04) with Windows 7. Both hard drives are SATA. I am using the default grub bootloader on my second hard drive. The windows drive is unmodified. To get to grub, I changed the hard disk boot priority in my BIOS (P35-DS3L) to boot from the second drive. The problem I'm having is that when I boot to Windows 7 (on sda) from grub (on sdb), Windows 7 will not go to sleep (from the start menu). The display shuts off momentarily as if its going to sleep, then comes back on and displays the switch-user screen. Powercfg -lastwake does not show anything. I am sure that this is related to booting from grub on sdb because when I change the hard disk boot priority in the BIOS to boot from my (unmodified) Windows hard disk, the computer goes to sleep fine. It occurred to me that installing grub on sda might solve the problem, but I'd rather not since I like to have my windows hard disk unmodified so that booting to it from the BIOS boots directly to windows. A possible work around is to use the BIOS as a bootloader, by pressing F8 to select the boot device. Still, I'd like to know why the problem is happening in the first place.

• Give back full control to a user on a disk from another computer

  - by Foghorn

  I have my friend's hard drive mounted externally. After messing with the permissions with TAKEOWN so I could fix some viruses, I have full control over their drive. The problem is, now it's stuck in a "autochk not found" reboot sequence. I think the problem is that the boot sector is invisible to the drive now. So my question is, How can I use icacls to give back the full ownership, when the user I am giving it to is not on my machine? I ran the TAKEOWN command from my windows 7 laptop, their machine is a windows xp Professional with three partitions, I only altered the one that has the boot sector. Here is the permissions that icacls shows: (Where my computer is %System% my username is ME, and the drive is E:\ C:\Users\ME icacls E:\* E:\$RECYCLE.BIN %System%\ME:(OI)(CI)(F) Mandatory Label\Low Mandatory Level:(OI)(CI)(IO)(NW) E:\ALLDATAW %System%\ME:(I)(OI)(CI)(F) E:\alrt_200.data %System%\ME:(OI)(CI)(F) E:\AUTOEXEC.BAT %System%\ME:(OI)(CI)(F) E:\AZ Commercial %System%\ME:(I)(OI)(CI)(F) E:\boot.ini %System%\ME:(OI)(CI)(F) E:\Config.Msi %System%\ME:(I)(OI)(CI)(F) E:\CONFIG.SYS %System%\ME:(OI)(CI)(F) E:\Documents and Settings %System%\ME:(I)(OI)(CI)(F) E:\IO.SYS %System%\ME:(OI)(CI)(F) E:\Mitchell1 %System%\ME:(I)(OI)(CI)(F) E:\MSDOS.SYS %System%\ME:(OI)(CI)(F) E:\MSOCache %System%\ME:(I)(OI)(CI)(F) E:\NTDClient.log %System%\ME:(OI)(CI)(F) E:\NTDETECT.COM %System%\ME:(OI)(CI)(F) E:\ntldr %System%\ME:(OI)(CI)(F) E:\pagefile.sys %System%\ME:(OI)(CI)(F) E:\Program Files %System%\ME:(I)(OI)(CI)(F) E:\RECYCLER %System%\ME:(I)(OI)(CI)(F) E:\RHDSetup.log %System%\ME:(OI)(CI)(F) E:\System Volume Information %System%\ME:(I)(OI)(CI)(F) E:\WINDOWS %System%\ME:(I)(OI)(CI)(F) Successfully processed 22 files; Failed processing 0 files C:\Users\ME

• I can't connect new Windows 7 PC to Mac iBook with OS 10.3.9

  - by Jeff Humm

  Help ! I have an old iBook wired to a router and a new PC linking wirelessly to same router. On the Mac I have 'seen' the PC but not been able to connect to it. On the PC, the Network and Sharing Centre lists 'IBOOK'. When I click on this, 'Windows Security' asks me to 'Enter Network Password', asking for User name and password. I have tried: 1) The user name and password of my admin account on the iBook. This returns a 'logon failure' message but lists the user name as [NAME_OF_PC\User Name], suggesting it was looking for the user name of the PC, not the Mac. 2) The user name and password of my account on the PC. This also returns a 'logon failure' message. 3) The user name of my account on the PC and the 'homegroup password' given to me by Windows when setting up the PC. This also returns a 'logon failure' message. Today I've tried connecting the two machines via a patch cable - still no joy. Can anyone help? It is 20 years since I wrestled with any OS other than Mac, and 10 years since I've done mich wrangling with the Macs, so please assume no knowledge! Thanks in advance,

• Joining an Ubuntu 14.04 machine to active directory with realm and sssd

  - by tubaguy50035

  I've tried following this guide to set up realmd and sssd with active directory: http://funwithlinux.net/2014/04/join-ubuntu-14-04-to-active-directory-domain-using-realmd/ When I run the command realm –verbose join domain.company.com –user-principal=c-u14-dev1/[email protected] –unattended everything seems to connect.

• DIR $file "File Not Found" vs DIR $filedir shows it....not permissions, not USB

  I was having this problem before on a USB drive, but now it's happening on my main RAID5-backed hard disk: 2013-10-17 9:37 C:\>dir "C:\Shares\Shared\Reference\Safety Management System\Vid eo CD\AutoPlay\Docs\Manuel*" Volume in drive C has no label.

I opened it, had it run as me with the "restricted access" unchecked, then ran the above. The file in question has the following ACLs: Administrators, SYSTEM, and OurCompanyUsers. All three have full control of everything. Nobody has any Deny bits set. I am a member of Administrators. So I don't believe it's a permissions issue. It's not a USB drive, so this time there is no question of USB hardware. Windows Server 2003 Standard Edition SP2. What does this mean? Is this more likely a hardware or software problem?

• Protocol to mount fat32 network filesystem on Linux with ability to lock files ( not advisory locks

  - by nagul

  I have a fat32 filesystem sitting on a NAS storage device (nslu2) that I need to mount on my Ubuntu system. I've tried Samba and NFS mounts, but both don't seem to support proper locking. More specifically, I am unable to save files to the mounted drive through GNUcash, KeepassX etc, which makes the share fairly useless. Is there a protocol that allows me to achieve this ? Note that the NAS storage device is running a linux OS so I can run pretty much any protocol that has a linux implementation. The only option I'm not looking for is to reformat the partition to ext3, which I'm not able to do due to other constraints. Alternatively, has anyone managed proper locking of a fat32 system over the network using Samba ? Or, is advisory locking the best you get with a network-mounted fat32 file system ? I've thought of trying sshfs but I've not found any indication that this will solve my problem. Edit: Okay, maybe I can reformat the drive, but to any file system except ext3. The "unslung" nslu2 doesn't like more than one ext3 drive, and I already have one attached. So any solution that involves reformatting the drive to ntfs, hfs etc is fine, as long as I can mount it on linux and lock files.

• Thunderbird alerts when expected email does not arrive

  - by user871199

  I am on Ubuntu 12.04 using Thunderbird as email client. Both are up to date in terms of updates. I have bunch of nightly jobs that do the work and send a status mail. It gets tedious if you keep getting same/similar mails every day so I ended up writing a mail filter rule which causes emails to end up in their respective folders automatically. If things are going ok, I really don't need to read emails. Failure emails are sent to different alias - if the job runs. We recently discovered that one of the job had not run for few days as someone accidentally disabled it. In order to avoid such problems in future, I would like to setup thunderbird in such a way that if I don't get email from given address within given duration, it should alert me. My dream solution is to set up frequency - some jobs do run every 4 hours. Is this possible? Can I setup Thunderbird (preferred) or other email client for reminding me when expected email does not show up. Based on comments and answer I received, here are the reasons why I would like to use Thunderbird. We are already using Thunderbird. It has calender support via plugin, so I suppose someone is already watching time to remind us about the event. May be this another type of event. Additional job is one more failure point, may complicate life if it has to monitor multiple hosts. Additional tools - same thing, one more failure point. Thunderbird can be run across all the platforms we are using - Windows and Ubuntu. It sort of becomes platform independent solution.

• Robocopy launches and then hangs/just sits there

  - by NateO

  I'm setting up an archive process to store old files on an external hard drive. The computer in question is running Windows 7 Pro 32bit. We have a server folder with 150,000+ files in it, most of which are pretty small (below 200k). I'm trying to use robocopy in a batch file to do this. It was working fine the other day, now all it does upon launch is sit there. It shows me all the options and whatnot, and also lists the number of files in the directory and the directory itself, but it never gets past that line. If I switch the destination to the local C drive, it eventually starts copying files. Is there something in my batch file that needs to change? Or could there be a problem with the external Western Digital drive that I'm using? The WD drive currently is holding about 175,000 files. Here is the one line batch file I have: robocopy "\\cgifp01\Prepress\Public\ImportedPDF" "E:\OldFiles" *.* /R:2 /W:10 /MINAGE:15 /MOV /B /XJ /XF "blank_test.pdf" Thanks for any tips or ideas. Nate

• How to configure SCSI hard drives and RAID for Poweredge 2850 web server

  - by Saul

  I'm trying to set up a Poweredge 2850 as a web server, but as a server novice it's causing me some confusion. Its a virgin install so no data to be lost as yet, so I'd like to get the best arrangement for setting up Windows Server 2008. The box will run IIS, a mail and FTP server. The current physical arrangement of the hot swap drives is 1 73GB 3 146GB 5 blank 0 73GB 2 146GB 4 146GB (but flashes green, amber off) When I enter the PERC config screens on boot up I've got Raid Ch- 0 ID 0 ONLIN A00-00 1 ONLIN A00-01 2 ONLIN A01-00 3 ONLIN A01-01 4 HOTSP I think that drives 0 and 1 are set to RAID 1 and drives 2 and 3 are also set to RAID 1, certainly I can see 2 logical drives, both raid 1 of 69880MB and 139900MB Now what I think I am getting here is that the 2 73GB drives mirror each other and the 2 146GB drives mirror 2? so by my noob thinking if a drive fails I can pull it, insert and new one and it will reduplicate from its matching pair? I think the flashing amber probably indicates a failing drive in slot 4, should that just be binned? What confuses me coming from a home user XP background is that when I load up Windows Server 2008 OS under my computer I only see a C drive of about 70GB capacity. i.e wheres the 146GB drive? Any advice appreciated

• Files on ext4 on Drobo with corrupt, zero-ed out blocks

  - by Patrick

  I have a 2TB ext4 file system (Ubuntu running Linux kernel 2.6.31-22-server x86_64). This file system is the second drive on a Drobo box plugged in via USB. We've not had problems on the first drive (Drobo limits drive size to 2TB due to some OS limitations, so if you have more space than that it appears as two separate drives). I am sharing this files with Samba (smbd 3.4.0) with a mix of Windows and Linux workstations. Recently we've been experiencing some data corruption in multiple files. In many cases I have an un-corrupt original file stored on one of the workstations. These are binary files of various formats, (e.g. SQLite, but others as well). I used "split" to split a corrupt and uncorrupt file into 4096 byte chunks (this is the block size of the ext4 file system). I then ran md5sum on pairs of chunks and discovered that the chunks matched in many cases and in every case where they did not match, the corrupt chunk was a solid chunk of zeroes (620f0b67a91f7f74151bc5be745b7110 for what it's worth). I'm trying to track down a culprit but am a bit at a loss. I don't believe Samba is at fault since I'm using it without issue on the first drive exported by the Drobo. What can I do to narrow this down and find out what's going on?
