• What are "Excess Fragments" in defragmenting a hard drive?

  - by Andrew Swift

  I'm defragmenting my hard drive (XP SP3) with PerfectDisk 7.0, and it finds 816,659 excess fragments when I ask for an analysis. [update] Specifically, it shows that the 1TB disk is 14% fragmented with 19693 fragments and 816,659 excess fragments. About 20% of the disk is still free space. What does excess fragments refer to? What is the difference between fragments and excess fragments? I have had problems in the past where I defragmented a fragmented disk and many files were corrupted. It seemed as though "excess fragments" referred to orphan pieces, where the program couldn't find out where to put them. If that was true, then defragmenting a disk resulted in many incomplete files, and in fact I defragmented a disk full of MP3's and got a lot of corrupted files as a result. Instead, I started to simply format a separate disk and copy everything from one to the other. That way there were no orphan bits, and no file corruption. Does anybody know what "excess fragments" really are?

• Missing boot files in Windows 8

  - by Alex F. Sherman

  I had a partition with Windows 8 Release Preview, Windows' System Reserved partition and the empty space of the beginning of disk. I moved two partitions to the beginning of disk using Ubuntu Live CD and GParted. After that, the Windows Loader didn't boot and throw an error about missing files. I fixed it using the commands: bootsect /nt60 sys /force /mbr bootrec /rebuildbcd bootrec /fixboot bootrec /fixmbr When I used "Automatic repair" option from "Advanced boot" menu, it throw an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt In this file I found a description of the system repair actions and at the end of file: Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings - General - Advanced startup) I receive an error: Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090. 0x80070490 is the error code ERROR_NOT_FOUND. What are the missing boot files and how can I restore them? List of files in System Reserved Partition: B:\bootmgr B:\BOOTNXT B:\Boot\BCD B:\Boot\BCD.LOG B:\Boot\BCD.LOG1 B:\Boot\BCD.LOG2 B:\Boot\BOOTSTAT.DAT B:\Boot\Fonts B:\Boot\memtest.exe B:\Boot\qps-ploc B:\Boot\Resources B:\Boot\Resources\bootres.dll and many *.mui and *.ttf files.

• undelete big files - mission impossible?

  - by johnrembo

  Hi, I've accidentaly deleted outlook.pst (6.7GB) file, while there was only 400MB free space left on primary NTFS partition (winxp). I've tried several recovery tools to get this file back. "Ontrack Easy Recovery Pro" found 0 pst files (complete scan mode), while "Recover My Files" in sector scan mode found 5 pst's, but 4 of them of sizes from 3 to 28 KB, while the 5th one - 1Gb. I've managed to succesfuly recover 1Gb pst file, which was 1 year old copy (the one used after the latest windows reinstall). Now, I'm frustrated and confused Why 1 year old file was succesfuly recovered if there were only 400MB left on primary partition? Where's 6.7GB file gone? I did some reading (i.e. here), and it seems that there's almost no probability to retrieve the file I'm looking for, but wait - none of recovery tools i've used found zero-sized pst file, moreover - if due to fragmentation a file might be corrupted - we could use scanpst.exe to fix some errors and survive with 10 or 100 emails missing - whatever. Could you please recommend some more sophisticated recovery tools for this particular task? Appretiate your help - thanks in advance

• Running a VM off a USB 2.0 Flash Drive - Mac/Parallels/XP

  - by geerlingguy

  I use a MacBook Air as my primary machine, and the 128GB SSD means space is precious. To save about 10 GB, I've been running Parallels with a Windows XP VM off an external USB hard drive, which performs as well in everyday use as running the VM off the internal SSD. So, I bought a tiny 32GB USB 2.0 flash drive, plugged it into the MacBook Air, formatted it first as ExFAT (which was slow), then as Mac OS Extended (Journaled) (which was also slow), and copied over my VM file, and ran Parallels off it. My full experience is documented here: http://www.midwesternmac.com/blogs/jeff-geerling/running-windows-xp-vm Straight file copies are really fast — 30 MB/sec read (solid the whole time), and 10-11 MB/sec write (solid the whole time). But I noticed that once XP started running, the disk access rates were in the low KB ranges. Are USB flash drives really that poor at random access, or could I possibly be missing something (the format of the flash drive, etc.?)? Of note, I've tried the following, to no great effect: Formatting the drive as either ExFAT or Mac OS Extended (Journaled) Unplugging all other USB devices and turning off Bluetooth (which runs on the right-side-port USB bus). Plugging in the flash drive either direct in the right side port, or the left side port, or into a USB 2.0 hub

• Win 2008 R2 - copying TO disk is very slow, copying FROM is more or less okay

  - by avs099

  I have Windows 2008 R2 SP1 with 4 identical SATA disks (Seagate Barracude 7200) in RAID 5 array. It has 4Gb of memory; all recent updates are installed. Problem: when I copy large file from one folder to another, I get about 10MB/s average speed. When I read this file from network share via 1Gbps connection - I get about 25-30 MB/s. Both numbers seems to be low for me - but specifically I'm very frustrated with low write speed. there is no antivirus, no hyper-v, it's just a fileserver - i when i do my tests nobody else reads/write from it (we have only 4 people in a team, so I'm sure). Not sure if that matters, but there is only 1 logic disk "C" with all available space (1400 GB). I'm not an admin at all, so I have no idea where to look and what other information to provide. I did run performance monitor with "% idle time", "avg bytes read", "avg byte write" - here is the screenshot: I'm not sure why there are such obvious spikes. Any idea? Please let me know if you need me to provide more information - what counters should I check, etc. I'm very eager to get this solved. Thank you. UPDATE: we have another Windows 2008 R2 SP1 server with 2 RAID1 arrays - one is disk C (where windows is installed, another one is disk E). It is running Hyper-V and does not have antivirus. I noticed the following behavior when I copy large file (few GBs): C - C: about 50MB/sec C - E: about 55MB/sec E - E: 8MB/sec!!! E - C: 8MB/sec!!! what could cause this?? E drive is RAID1 array from same Seagate Barracuda 1TB drives..

• Access Windows Boot Manager selector when timeout is set to 0?

  - by Kyle Cronin

  I've installed Wubi onto a Windows Vista computer. I've also set the boot timeout to 0: bcdedit /timeout 0 However, now I can't figure out how to get the menu to come up at all! I read on the internets that I had to hold F8 or space when starting up, but they doesn't seem to do anything. Is there a different key or setting I've overlooked? The computer itself is a Dell that's a few months old. The keyboard is USB, but I don't think that's the problem as I can get into the BIOS just fine. Maybe I'm doing it wrong? Am I supposed to hold the keys or rapidly tap them (I've tried both)? If it helps, here's the output from bcdedit: C:\Windows\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=C: description Windows Boot Manager locale en-US inherit {globalsettings} default {current} resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} displayorder {current} {e2484fe7-5e97-11de-84d4-0024e8074422} toolsdisplayorder {memdiag} timeout 0 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Windows Vista locale en-US inherit {bootloadersettings} recoverysequence {572bcd55-ffa7-11d9-aae0-0007e994107d} recoveryenabled Yes osdevice partition=C: systemroot \Windows resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} nx OptIn Real-mode Boot Sector --------------------- identifier {e2484fe7-5e97-11de-84d4-0024e8074422} device partition=C: path \ubuntu\winboot\wubildr.mbr description Ubuntu

• Concerns about Apache per-Vhost logging setup

  - by etienne

  I'm both senior developer and sysadmin in my company, so i'm trying to deal with the needs of both activities. I've set up our apache box, wich deals with 30-50 domains atm (and hopefully will grow larger) and hosts both production and development sites, with this directory structure: domains/ domains/domain.ext/ #FTPS chroot for user domain.ext domains/domain.ext/public #the DocumentRoot of http://domain.ext domains/domain.ext/logs domains/domain.ext/subdomains/sub.domain.ext domains/domain.ext/subdomains/sub.domain.ext/public #DocumentRoot of http://sub.domain.ext Each domain.ext Vhost runs with his dedicated user and group via mpm-itk, umask being 027, and the logs are stored via a piped sudo command, like this: ErrorLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_error.log" CustomLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_access.log" combined Now, i've read a lot about not letting the logs out of a very restricted directory, but the developers often need to give a quick look to a particular subdomain error log, and i don't really want to give them admin rights to look into /var/logs. Having them available into the ftp account is REALLY handy during development stages. Do you think this setup is viable and safe enough? To me it is apparently looking good, but i'm concerned about 3 security issues: -is the sudo pipe enough to deal with symlink exploits? Any catches i'm missing? -log dos: logs are in the same partition of all domains. got hundreds of gigs, but still, if one get disk-space dos'd, everything will break. Any workaround? Will a short timed logrotate suffice? -file descriptors limits: AFAIK the default limit for Apache on Ubuntu Server is currently 8192, which should be plenty enough to handle 2 log files per subdomain. Is it? Am i missing something? I hope to read some thoughts on the matter!

• Looking for equivalent of ProxyPassReverseMatch in Apache to fix missing trailing forward slash issue

  - by Alex Man

  I have two web servers, www.example.com and www.userdir.com. I'm trying to make www.example.com as the front end proxy server to serve requests like in the format of http://www.example.com/~username such as http://www.example.com/~john/ so that it sends an internal request of http://www.userdir.com/~john/ to www.userdir.com. I can achieve this in Apache with ProxyPass /~john http://www.userdir.com/~john ProxyPassReverse /~john http://www.userdir.com/~john The ProxyPassReverse is necessary as without it a request like http://www.example.com/~john without the trailing forward slash will be redirected as http://www.userdir.com/~john/ and I want my users to stay in the example.com space. Now, my problem is that I have a lot of users and I cannot list all those user names in httpd.conf. So, I use ProxyPassMatch ^(/~.*)$ http://www.userdir.com$1 but there is no such thing as ProxyPassReverseMatch in Apache. Without it, whenever the trailing forward slash is missing in the URL, one will be directed to www.userdir.com, and that's not what I want. I also tried the following to add the trailing forward slash RewriteCond %{REQUEST_URI} ^/~[^./]*$ RewriteRule ^/(.*)$ http://www.userdir.com/$1/ [P] but then it will render a page with broken image and CSS because they are linked to http://www.example.com/images/image.gif while it should be http://www.example.com/~john/images/image.gif. I have been googling for a long time and still can't figure out a good solution for this. Would really appreciate it if any one can shed some light on this issue. Thank you!

• Why is Safari on my computer rendering all of the colors -- not just for images -- incorrectly?

  - by richardhenry

  I’m not just talking about image color profile issues; every single color that the browser renders is incorrect. It’s like it’s in it’s own color space (or something!). Screenshot: http://drp.ly/DJk1O (Opera, Safari, Chrome, Firefox) Spot the odd one out? Open this up in Photoshop or similar and try using the eyedropper to select the colour. Safari renders the same hex color completely differently. That color is set using a background-color declaration in CSS, so it should be identical in all four of those browsers. Here’s the HTML I was using: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>untitled</title> <style type="text/css"> body { background-color: #114742; } </style> </head> <body> </body> </html> Literally every website I’m viewing with my install of Safari is displaying colors incorrectly. The blue of the bar on Facebook is slightly less rich. This doesn’t occur on any other Macs I’ve tried. Any idea what’s happened to my Safari install?

• Surprising corruption and never-ending fsck after resizing a filesystem.

  - by Steve Kemp

  System in question has Debian Lenny installed, running a 2.65.27.38 kernel. System has 16Gb memory, and 8x1Tb drives running behind a 3Ware RAID card. The storage is managed via LVM. Short version: Running a KVM guest which had 1.7Tb storage allocated to it. The guest was reaching a full-disk. So we decided to resize the disk that it was running upon We're pretty familiar with LVM, and KVM, so we figured this would be a painless operation: Stop the KVM guest. Extend the size of the LVM partition: "lvextend -L+500Gb ..." Check the filesystem : "e2fsck -f /dev/mapper/..." Resize the filesystem: "resize2fs /dev/mapper/" Start the guest. The guest booted successfully, and running "df" showed the extra space, however a short time later the system decided to remount the filesystem read-only, without any explicit indication of error. Being paranoid we shut the guest down and ran the filesystem check again, given the new size of the filesystem we expected this to take a while, however it has now been running for 24 hours and there is no indication of how long it will take. Using strace I can see the fsck is "doing stuff", similarly running "vmstat 1" I can see that there are a lot of block input/output operations occurring. So now my question is threefold: Has anybody come across a similar situation? Generally we've done this kind of resize in the past with zero issues. What is the most likely cause? (3Ware card shows the RAID arrays of the backing stores as being A-OK, the host system hasn't rebooted and nothing in dmesg looks important/unusual) Ignoring brtfs + ext3 (not mature enough to trust) should we make our larger partitions in a different filesystem in the future to avoid either this corruption (whatever the cause) or reduce the fsck time? xfs seems like the obvious candidate?

• Chrome's new window disappear from desktop

  - by faulty

  I'm having this problem with Chrome on a Windows 7 x86 machine. I'm using Chrome for a locally hosted intranet web app. In the web app, there's frequent use of new window which popup, which works like a dialog box for the app. The problem started since yesterday. All the new windows doesn't appear on top and no where to be found on the desktop. But it does appear on the taskbar. Clicking the button on the taskbar doesn't bring up the window as well. I've also tried Alt+Space, then Move, it doesn't work. I only found 2 way to bring it up, Maximize or Show as tab. What could have caused this and how should I fix it? Thanks EDIT: I've configure to not group taskbar buttons. EDIT: I've just gone through the javascript of the button, it call window.open to display the popup. I can see the popup flicker and disappear. If I step through the code, the popup will display properly, sometime. Also, if I click the button twice, it will also display the popup, but at a much smaller size, less than 100x100

• Automounting Active Directory home drives on a Linux server on login

  - by Ethan

  I've got a Centos 5.7 box authenticating against Active Directory through PBIS Open (the new LikeWise Open), which works well. Now, I'm trying to get the server to automount the user's AD home directory, located at //ad.server.dom/shares/home directories (Yeah, it's a space in the path. I didn't set this up). Each user has a directory in there with the same name as the user. I've tried to get pam_mount working, but it has a series of issues on RedHat and friends, and I can't seem to get that working. The directory does need to be automounted for the server to perform it's role. My reading on automount seems to suggest that there's no way to get it to do it's thing with authentication, though I'm happy to be proved wrong. I've looked at this resource, but it requires version RedHat (thus CentOS) 6 or higher, and newer packages than I have. I can manually (As root) mount the AD directory using the command mount.cifs "//ad.server.dom/Shares/home directories/testuser" /home/local/AD/testuser/nfs_mount/ -o username=testuser and when I log in as testuser, I can see all of the sample files in the nfs_share directory. Any tips towards the right direction would be highly appreciated. This is going to be on a server at a college, so it needs to be fairly stable, and would lead towards more Linux adoption there.

• Recovering a damaged microSDHC

  - by djechelon

  I just bought from eBay a Kingston 32GB microSDHC that was advertised as defective. The seller said that there could be formatting problems or with transfer of large files. Unfortunately, when I got it, it was a total mess. My Nikon camera doesn't read it at all (OK, maybe it doesn't support 32GB) My Linux laptop doesn't mount it: can't read superblock The same laptop refuses to mkfs.msdos because it failed whilst writing reserved sector The same laptop, under Windows, doesn't read nor format the card HTC HD2 mounts the MMC, allows me to write via USB, but is unable to open the just written files OK, folks, now you would say I would have to go through Paypal complaint... that's not that easy. I consciously bought a half-price card that was known to show some defects, and Paypal complaints take time. Obviously, I can't accept somebody sold me a completely use-less computer decoration. So I'll keep it as last option. My question is Do you know a way, under either Linux or Windows, to thoroughly scan, test and possibly repair memory cards, even if I have to lose some percentage of space because of bad sectors? If I can keep at least half of the card intact it would certainly be fine. I used to do broken sector marking with hard disks in the past. I almost forgot: MONSTR:/home/djechelon # fsck /dev/mmcblk0p1 fsck from util-linux-ng 2.17.2 dosfsck 3.0.9, 31 Jan 2010, FAT32, LFN Read 512 bytes at 0:Input/output error

• Linux Uninstalling errors

  - by Zack

  I want to uninstall back-track 5 so I deleted the partitions for back-track os. After deleting the partition that used to be for back-track becomes free space as in picture. But I can't delete that partition nor creating a new partition. I used G-Parted from hiren boot cd but it says there is no partition table, you need to create a partition table. But actually I have 5 partitions already. And I thought of restarting might fix it. But after showing post screen my laptop show grub error. I don't know what to do, and I tried to install back-track again to fix the problem but it also says that i do not have any partitions. I can only boot windows by passing through hiren boot cd. But most of the time My computer is not recognizing the external dvd drive, nor the internal so i have to restart again and again, hoping to catch the time computer recognize the dvd drive. Can I change the boot loader to correct the grub error? SOLVED : I have solved the grub error by writing MBR again by using EasyBCD But I still have the format error.

• PDU management interface has low availability - product flaw or isolated issue

  - by DeanB

  Our colocation provider has supplied us with APC AP7932 switched 0U PDUs as part of several cabinets they provide us. We have had a lot of trouble with the network management aspect of these PDUs, which I'll describe below. We are moving to cage space in the same datacenter, and plan to provide our own PDUs, so I'd like to determine which enterprise-grade PDUs have been reliable performers from a remote management perspective. Our colo-provided PDUs are configured to support management via an SSL web UI and via telnet. We updated the firmware on all of them to the current version as of NOV2011. They respond to pings reliably, and we have no reason to suspect a network layer issue. However, we experience frequent hangs, timeouts, disconnects, and general unavailability from the embedded management host in all of the PDUs. We occasionally have to restart the microcontroller on the PDU to recover from what appears to be an occasional hard fault. The outlets stay powered (thankfully), but the management aspect is so unreliable that it has become an ops liability - we can't be confident that we could get into the PDU to power cycle a host if we needed to. We have 3 PDUs that all exhibit identical behavior. There are many manufacturers of enterprise-grade 0U switched PDUs, all with comparable features. If I looked at the datasheet for our current PDUs, they would appear to be a good fit -- only with the benefit of suffering through using them do we know to avoid them. I'd like to avoid picking a PDU that looks fine on paper, but has similar reliability issues. What has been others' experience with switched PDUs? Is this level of flakiness normal?

• Need advice on a monitoring, reminder and warning application.

  - by cbmeeks

  I am a developer that also has to monitor several things on different servers. Such as: 1) Did all of the MS SQL databases backup last night? 2) Did all of the MySQL databases backup last night? 3) Were the database dumps actually copied to the right folder? 4) How much free space is left on each server's hard drives? 5) How big are folders "abc", "def", "etc" getting? 6) Send emails/alerts when thresholds are reached Etc. Just basically something to help me NOT forget such important things. I thought about writing something myself but didn't want to waste the effort if something is already out there. I would also prefer one application instead of many if I could. Thanks. EDIT Forgot to mention the operating system. These run on Windows Server 2003 and/or 2008. In fact, what would be cool is a program that supports multiple servers from one machine. Something that can log into those servers.

• Recommendations for hosting large videos

  - by Clinton Blackmore

  I recently created and put a 45-minute, 300 MB video file on my website and told a mailing list about it. Checking my site stats, I see that I've used 20% of my "unlimited" bandwidth for the month. As I want to be able to have several videos like this, clearly, I need to consider other options. The appeal to hosting files as my own site (aside from the supposedly unlimited disk space and bandwidth), is to be able to have control over the format, resolution, and quality of the video(s), as well as to ensure that it is clear that I'm the copyright holder (although the videos will be under a creative commons license). I find that for the screencasts I'm making, having a high resolution (say 3/4 of 1024 * 768) really makes seeing what is going on on the screen easier. It is also always a plus to not have the experience marred by advertisements. One more wrench to throw in is that while the videos are non-commercial, they do promote a club, and it seems that that falls afoul of some terms of services (especially for free services; while free is very nice, I will certainly consider putting up some money.) What recommendations do you have for (fairly) long, high-resolution videos? Should I look in depth at sites like YouTube and Vimeo, should I be considering a filesharing site [I have no qualms with someone downloading the entire video first -- I wouldn't want to watch 45 minutes in my browser!], hosting files with Bittorent (ugh -- I think that'd reduce my audience), or should I be looking into other web hosts (and if so, who?)

• Scanning website for vulnerablities

  - by Kristen

  I have found that the local school's website installed a Perl Calendar - this was years ago, it has not been used for ages, but Google has it indexed (which is how I found it) and it full of Viagra links and the like ... program was by Matt Kruse, here is details of the exploit: http://www.securiteam.com/exploits/5IP040A1QI.html I've got the school to remove that, but I think they also have MySQL installed and I'm aware that out-of-the-box there have been some exploits of Admin Tools / Login in old versions. For all I know they also have PHPBB and the like installed ... The school is just using some cheap, shared hosting; the HTTP response header I get is: Apache/1.3.29 (Unix) (Red-Hat/Linux) Chili!Soft-ASP/3.6.2 mod_ssl/2.8.14 OpenSSL/0.9.6b PHP/4.4.9 FrontPage/5.0.2.2510 I'm looking for some means of checking if they have other junk installed (quite possibly from way back, and now unused) that might put the site at risk. I'm more interested in something that can scan for things like the MySQL Admin exploit rather than open ports etc. My guess is that they have little control over the hosting space that they have - but I'm a Windows DEV, so this *nix stuff is all Greek to me. I found http://www.beyondsecurity.com/ which looks like it might do what I want (within their evaluation :) ) but I have a worry about how to find out if they are well known / honest - otherwise I will be tipping them a wink with a Domain Name that may be at risk! Many thanks.

  Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.

• Cannot access drive in Windows 7 after scandisk lockup, but can in safe mode....

  - by Matt Thompson

  I ran scandisk on my external USB drive due to the inability to delete a few files. Windows asked me if I wanted to unmount the drive before the scan, warning me that it would be unusable until the scan was finished, and I said yes. During the scan, my machine locked up, and I was forced to reboot the machine. When it came up, I was unable to access the drive, getting an error that "L:is not accessible, access is denied". Comupter Management sees the drive, and has the proper amount of disk space filled. I booted into safe mode, and can access the drive with no problems, and I noticed that in explorer, all the folders have locks on them. I booted back into windows, but still could not access the drive, getting the same error as above. Hovever, if I right click on the drive, select properties, and go to Customize, in the folder pictures ares, I select Choose File, and a window open up, that shows the root of the directory, with all the folder able to be accessed, but again, the icon is the folder icon with a lock on it. I can even copy files from the drive to another. So, the files are not gone, windows can obviously access the drive no matter what it thinks, so there has to be a problem with the flag windows put on the drive when it ran the original scan that failed. I was able to run a scan both in safe mode with no problems, and in windows. In windows, I received the cannot access error the first time I run scan disk on it, but if I try again, it works fine. Any ideas on how to clear the flag that windows set, so I can access the drive normally again?

• Millions of files in php's tmp error - how to delete?

  - by Jonatan Littke

  Hey. I've got a tmp-folder with 14 million php session files in my home directory. At least that's what I think it is, it's not like I could ls it or anything. How can I empty this folder? I've tried using find with the -exec rm {} \; commands but that didn't work. ls 'sess_0*' | xargs rm did neither. I'm currently running rm -rf tmp but after two hours the folder appears to be the same size. REFERENCE INFO: I suddenly encountered an error where SESSIONS could no longer be written to disk: [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: open(/var/www/clients/client1/web1/tmp/sess_8e12742b62aa68a3f9476ec80222bbfb, O_RDWR) failed: No space left on device (28) in Unknown on line 0 [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/clients/client1/web1/tmp) in Unknown on line 0 I ran: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 457G 126G 308G 29% / tmpfs 1.8G 0 1.8G 0% /lib/init/rw udev 10M 664K 9.4M 7% /dev tmpfs 1.8G 0 1.8G 0% /dev/shm But as you can see, the disk isn't full. So I had a look in the syslog which says the following 20 times per second: kernel: [19570794.361241] EXT3-fs warning (device md0): ext3_dx_add_entry: Directory index full! This led me thinking to a full folder, obviously, but since my web folder only has 60k files (having counted them), I guessed it was the tmp folder (the local one, for this instance of php) that messed things up. Some commands I ran: $ sudo ls sess_a* | xargs rm -f bash: /usr/bin/sudo: Argument list too long find . -exec rm {} \; rm: cannot remove directory '.' find: cannot fork: Cannot allocate memory I'm running Debian Lenny, php5, ISPConfig, SuEXEC and Fast-CGI.

• How do I increase the buffer size for domain sockets in OS X 10.6

  - by Chas. Owens

  In Linux I have no problem dumping tons of data into a domain socket, but the same code on OS X 10.6.2 blows up after about 65 records. The socket reader code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; unlink "foo"; my $sock = IO::Socket::UNIX->new ( Local => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; while (<$sock>) { chomp; print "[$_]\n"; } And the client code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; my $sock = IO::Socket::UNIX->new ( Peer => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; for my $i (1 .. 1_000_000) { print $sock "$i\n" or die $!; } close $sock; The error message I get is No buffer space available at write.pl line 15.. It seems fairly obvious that there is a difference in the buffer size between Linux and OS X, but I don't know how to set it OS X (or what the possible negative side effects might be).

• Looking for an application to record audio and video on a linux "embedded" device

  - by Luke404

  I am working with a linux x86 device with limited CPU resources (as a prototype we just use a pentium-m netbook). We'd like to record video from one V4L2 device (we'll probably end up using just USB Video Class devices like all modern webcams) and one audio stream from an ALSA source. The thing will not have screen and keyboard, and obviously no X11 environment. Goals are: do as little work as possible to cope with little cpu resources - for example I'd like to record video in the native MJPEG I get out of the UVC devices encoding audio to MPEG3 Layer-2 (aka mp2) is ok since it let us save a lot of space (compared to raw pcm samples) and does use little cpu power I don't mind loosing some video frames here and there (UVC devices do that) as long as I can get audio and video streams syncronized not require user input to start the thing (a python script takes care of initialization, startup, shutdown, etc...) be able to open the resulting files for postprocessing without too much effort (ie, if mplayer or vlc can play it, it's fine) So far the only app I found that could be started from command line and record V4L2 video + ALSA audio is mencoder but I'm having some difficulties with it. It should be able to do that but I cannot record audio and video together - just one of the two. And if I use two different processes to record to two different files I have no means to get them in sync (audio is more or less always correct, but video framerate will vary over time and it seems to lack timestamps to correctly play it back to the correct time). Long story short, how do you record an unconverted MJPEG stream (from an UVC device) and an audio stream (from an ALSA device, possibly encoding to any standard format) using a command line tool, to a single file (MPEG or any other container), keeping audio and video in sync?
