And yet another file system...

SpadFS - new experimental filesystem.

It has not got journaling!
Be carefull! it is impressive to see a new FS done for a tesis but... be carefull!

  • Crashes and read-only file systems

    Notice: I apolgize for the long post, I've tried to be as thorough as possible.  I have searched everywhere for possible solutions, but things I've found end up being temporary workarounds or don't apply to my situation.  Any help, even as simple as, "have you checked out XYZ log, it's hidden here", would be greatly appreciated.  Thanks
    I'm not sure what exactly caused the issues below, but they did start to happen within a day of running pacman -Syu.  I hadn't run that since I first installed Arch on December 2nd of this year.
    Setup:
    Thinkpad 2436CTO
    UEFI/GPT
    SSD drive
    Partitions: UEFISYS, Boot, LVM
    The LVM is encrypted and is broken up as: /root, /var, /usr, /tmp, /home
    All LVM file systems are EXT4 (used to have /var and /tmp as ReiserFS)
    The first sign that something was wrong was gnome freezing.  Gnome would then crash and I'd get booted back to the shell with all filesystems mounted as read-only.  I started having the same issues as this OP:
    https://bbs.archlinux.org/viewtopic.php?id=150704
    At the time, I had /var and /tmp as ReiserFS, and would also get reiserfs_read_locked_inode errors.
    When shutting down (even during non-crashed sessions) I would notice this during shutdown:
    Failed unmounting /var
    Failed unmounting /usr
    Followed by a ton of these:
    device-mapper: remove ioctl on <my LVM group> failed: Device or resource busy
    Nother of these errors had ever appeared before.
    After hours of looking for solutions (and not finding any that worked) I was convinced (without any proof) that my Reiser file systems were corrupt and so I reformatted my entire SSD and started anew - not the Arch way, I know   I set all logical volumes as EXT4.
    After started anew, I noticed
    device-mapper: remove ioctl on LVM_SysGroup failed: Device or resource busy
    was still showing up, even with just a stock Arch setup (maybe even when powering off via Arch install ISO, don't remember).  After a lot of searching, I found that most people judged it a harmless error, so I ignored it and continued setting up Arch.
    I set up Gnome and a basic LAMP server, and everything seemed to work for a couple of hours.  Soon after, I got the same old issues back.  The System-journald issue came back and per the workaround on https://bbs.archlinux.org/viewtopic.php?id=150704 and a couple other places, I rotated the journals and stopped journald from saving to storage.  That seemed to stop THOSE errors from at least overwhelming the shell, but I would still get screen freezes, crashes, and read-only file systems.
    I had to force the laptop to power off, since poweroff/reboot/halt commands weren't working (would get errors regarding the filesystems mounted as read-only).
    I utilized all disk checking functions possible.  From running the tests (SMART test included) that came as part of my laptop's BIOS to full blown fsck.  All tests showed the drive was working fine, and Fsck would show everything was either clean, or
    Clearing orphaned inode ## (uid=89, gid=89, mode=0100600, size=###
    Free blocks count wrong (###, counted=###)
    Which I would opt to fix.  Nothing serious, though.
    I could safely boot back into Arch and use the system fine until the system decides to freeze/crash and do the above all over again.
    The sure way of recreating this for me is to run a cron job on a local site I'm developing. After a brief screen freeze (mouse still moveable but everything is otherwise unreponsive) I'll systemctl status mysqld.service and notice that mysqld went down.
    It seems that it's at this point my file systems are mounted as read only, as trying to do virtually anything results in:
    unable to open /var/db/sudo/...: Read-only file system
    After some time, X/Gnome crashes and I get sent back to shell with
    ERROR: file_stream_metrics.cc(37)
    RecordFileError() err = 30 source = 1 record = 0
    Server terminated successfully (0)
    Closing log file.or_delegate.h(30)] sqlite erro1, errno 0: SQL logic error or missing database[1157:1179
    rm: cannot remove '/tmp/serverauth.teuroEBhtl': Read-only file system
    Before all this happened, I was using Arch just fine for a few weeks.  I wiped the drives and started anew, and this still happens with just the minimal number of packages installed.
    I've searched for solutions to each individual problem, but come across a hack that doesn't solve anything (like turning off storing logs for journal), or the solution doesn't apply to my case.
    At this point, I'm so overwhelmed I'm not even sure where exactly to pick up figuring this issue out.
    Thanks in advance for any help

    Did this occur when you booted from the live/install media?
    What is your current set up? That is, partitions, filesystems etc. I take it you have not yet reinstalled X but are in the default CLI following installation?
    If turning off log storage didn't help, reenable it so that you may at least stand a chance of finding something useful.
    What services, if any, are you running? What non-default daemons etc.?
    Does it happen if you keep the machine off line?
    Have you done pacman -Syu since installation and dealt with any *.pacnew files?

  • Backup and restore Root File system

    Hi
    Can I take backup of Root File system using ufsdump and later restore it (Root file system) completely using ufsrestore?
    Please give me the steps or a link
    Thanks in advance
    Ashraf.

    In short yes. But the steps depends on where you are going to store the backup and if you are running Sparc or x86 and what you do with your disk in between.
    Boot in single user.
    example# ufsdump 0cfu /dev/rmt/0 /dev/rdsk/c0t3d0s0
    /dev/rmt/0 (tape) can be another partions file /backup/root_backup
    For restore it must be safeest to boot from CD.
    Mount your disk to restore to under /a
    cd /a
    ufsrestore rf /dev/rmt/0 (or your file /backup/root_backup)
    If the partition is reformatted you may have to install new bootblocks.
    Please read some from docs.sun.com
    This is just an advice, not detailed workorder.....

  • Reloading iphoto library and streamlining iphoto file system.

    I had a hard-disk failure recently, and lost a lot of photos: basically all the full size files. Only the thumbnails remained on the system disk, so when I had the new drive installed, the engineer made these the iphoto library.
    Fortunately, I had most of my photos backed up on a separate harddrive (in the 'originals' folder). What is the best way of putting these into my iphoto library in place of the thumbnails already there? (ie, don't want to see both in iphoto).
    I'd put the iPhoto library on the separate hard-disk, but unbeknownst to me, about a year ago, iPhoto began saving imports on the system drive again, so these were the pictures I lost.
    On another point, since I installed iphoto 6, the location of photos has become confusing, with the whole photo library pre-iphoto 6 duplicated in a folders called 'Originals' and 'Data'. Neither of these maintain the original easily navigable and logical date hierarchy file structure, but have saved all photos in a folder marked 2007, by roll number. The date folders which remain only contain a 'data' folder containing .attr files. Not very practical.
    In short the whole thing is a mess: for some photos the system has saved 5 copies in various places.
    Is there anything that can be done to consolidate the iPhoto library and put it back on a date-based filing system?

    raggabishp
    To start at the end:
    Is there anything that can be done ... put it back on a date-based filing system?
    No, once you use iPhoto 6, that's the file system. But it's not that difficult to follow: A Note about the iPhoto Library Folder:
    In this folder there are various files, which are the Library itself and some ancillary files. Then you have three folders
    Originals are the photos as they were downloaded from your camera or scanner.
    (ii) Modified contains edited pics, shots that you have cropped, rotated or changed in any way.
    This allows the Photos -> Revert to Original command - very useful if you don't like the changes you've made.
    (iii) Data holds the thumbnails the the app needs to show you the photos in the iPhoto Window.
    Finding the Picture file is easy: There are three ways (at least) to get files from the iPhoto Window.
    1. Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
    2. File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
    3. Show File: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
    Rolls in the iPhoto Window correspond exactly with the Roll Folders in the Originals Folder in the iPhoto Library Folder. You can move photos between Rolls, you can rename rolls, edit them, create them, as long as you do it via the iPhoto Window. Check out the Info Pane (wee 'i', lower left) the name and date fields are editable. Edit a Roll Name using the Info Pane, the Roll Folder in iPhoto Library Folder/Originals will also have the new name.
    So the structure is different, but - especially if you use the Film Rolls view - very straightforward.
    There is no easy way to rid yourself of these 'thumbs become originals'. If the thumbs have the same filenames as the Originals, then you could overwrite the thumbs with the Originals, but you would need to do that on a file by file basis, I'm afraid.
    Other than that, compare the full size pics with the thumbs and trash the duplicates is all I can suggest.

  • HFS and case sensitive file systems

    I recently received a pre-installed Macbook. The file system is HFS+ (Apple_HFS according to 'diskutil list').
    This file system is not case sensitive but I would like it to be. Is there a way to deactivate the HFS wrapper responsible for that without formatting the disk and re-installing the OS from scratch ?

    I got issues synchronizing my linux account with my macosx account
    If it's home directory contents that's the issue, you might consider simply partitioning your drive and creating a separate home directory partition that is case sensitive, separate from the boot partition tht is not.
    Assuming you're on an Intel-based machine, you can resize the existing partition to make room, then create a new case-sensitive partition and move your home directory there.
    Now your account synchronization shouldn't have an issue and you didn't have to re-install the entire OS.

  • CS4 and Case Sensitive File Systems

    Does anyone know if CS4 will support case sensitive file systems?

    While I do wish all software companies including Apple completely
    supported the case-sensitive file system. Many don't. I cannot pull up
    an article, but I remember reading that Apple only recommended the use
    of the case-sensitive file system for OS X server and if memory serves
    even for that it only recommended it for the attached hard drives.
    We can lament the lack of support but if you really want to change the
    status quo for Adobe products then the only useful way to do so is:

  • Asmca has grayed out Volumes and ASM Cluster File Systems 11.2.0.3

    I've got a two node cluster which is up and running with the latest 11.2.0.3 grid install on Oracle Linux 6.3
    I need to get a shared storage location I can use for File I/O testing, ASM looks like the solution with an ASM Cluster File System.
    When I run asmca I do not have the ability to create these volumes or file systems as they are Grayed out.
    I found some instructions on how to get it to work, and they said to use acfsload to start up the required daemons:
    [root@oracleA bin]# ./acfsload start -s
    ACFS-9459: ADVM/ACFS is not supported on this OS version: '2.6.39-300.17.3.el6uek.x86_64'
    I installed Patches: 13146560, 14596051 - Which I thought would fix the problem. Rebooted after successfully applying the patches, but asmca still shows them greyed out
    and not supported on this OS error persists.
    I see some posts online saying to edit osds_acfslib.pm and update it to allow for the supported ORACLE version
    Right now it shows: ($release =~ /^oraclelinux-release/))) # Oracle Linux
    under /etc it only has oracle-release - could that have something to do with it not passing the check?
    uname -r
    2.6.39-300.17.3.el6uek.x86_64
    From what I can tell this kernal should support asm..
    Any help in getting these shared storage asm disks setup would be very helpful, oracleasm creates them and sees them fine for databases. Thanks.

    Turns out the Kernel version 2.6.39 does not have support for the ASM Drivers for the ACFS mounting.
    I'm going to have to use Oracle Linux 6.2 (instead of Oracle Linux 6.3) and rebuild my RAC to get a supported version of the drivers -> Kernel version 2.6.32

  • Oracle Express Edition And Windows Encrypted File System (EFS)

    Hello,
    I want to use oracle express edition with windows encrypted file system. I tried some possibilities like encrypting xe folder. But connection can not be established when efs is used. Is there a compatibility problem between oracle xe and windows efs? On Oracle's page, it is declared that oracle database is compatible with Windows EFS.
    Thank you for help.

    Pl identify which version of Win 7 - 32-bit or 64-bit ? Home version or something else ?
    The 11g XE install is only available for 32-bit version of Win 7 Professional or higher - http://docs.oracle.com/cd/E17781_01/install.112/e18803/toc.htm#BABHICJH. If you are installing on 64-bit version or Home version of Windows, then you are on your own. What is the reason for enabling EFS on this database ?

  • New Macbook and Linux(ferdora) file system ext3

    Hello all.
    I am getting a new Macbook.
    My home file server runs Fedora Core5 with a file system of ext3.
    Will the Mac be able to have read/write access?
    I did not know if anyone has any experience with this?
    I want to use the mac as my day to day computer but keep much of my files on my home linux box. That way I can keep adding drives.
    Also.. under linux I can map a drive or folder to any folder
    I want .... so that the network drive appears to be a folder in the file system and not new drive.
    Is this possible in the apple world?
    Thanks for the insight.
    T

    I am in the LINUX world.
    I am moving to a Apple world just for my "interface" and form factor.
    I use notebooks as my primary computer. You cannot beat the form factor and the "cool" factor of the macbook.
    Getting linux to work on a laptop with all of different configs is difficult. I have 2 that work but they are not as "slick" as the macbook.
    therefore I am planning to use a macbook as my primary computer and have linux (fedora) running on my home based computers, File server, guest computer etc.
    Thanks for your help. Samba would work. But I was hoping for a more direct connection and the ability to mount a drive/folder in my mac filesystem. - which I do not know the mac file system at all.
    Thanks again. I am off to google somemore... and see what I turn up.

  • Wine and yet another font problem

    So I upgraded my system (had to load lots of stuff, Xorg, Wine, the kernel..) and now my Wine fonts look like this:
    http://koti.kapsi.fi/anpurola/winecfg.png
    Some fonts are ok, but most of them are unreadable. I mostly run poker clients. I tried to delete my .wine directory, and install fonts again with winetricks, didn't help.
    Does this have something to do with the new Xorg? I had to remove RgbPath and AutoAddDevices from xorg.conf BTW, to get it work.

  • Extracting file from blob and storing in file system

    In order to keep the database size down, I would like to run a program to execute on submit of a page containing a file upload control, which will extract the file from the blob in the db and store it in the operating system.

  • Yet another file sharing question...

    So I've read the posts and several articles and I still can't get this thing to work.

    2) MacLeopard as the client with user 'administrator' an admin account.

    1) Administrator/groupAdmin (same as Lion,

    I'm trying to mount both shared folders on Leopard
    can I use two different login from Leopard
    do permissions effect file sharing

    Right, I think I've got it...
    I'm trying to logon from a Leopard machine to a Lion machine that has got two shared folders created on it using different accounts.
    I can logon to one shared folder with the appropriate account, that preserves the users and permissions, but when I try to logon to the other shared folder Leopard does not present the logon window and used the previous logon details that messes up the users and permissions.
    Am I going about this the right way? And if so wht can't I use two different logon details for the respective accounts?

  • And yet another reverse telecine question. =)

    Okay so I shot the footage in 24p advanced on a dvx100b. I batch reverse telecined in cinema tools. It worked fine except for the first frame of some of the final reverse telecined files. Only on some of the files (randomly) the first frame is interlaced. This only happened to some of the files and it is not really a big deal because there is nothing important usually in the first frame but it is a little worrying. Could it be because I didnt really pay attention to which of the 5 frame set (0-5/A-D frames where frame 3/C is the interlaced frame in 24p advanced) was captured as the first frame during capturing? I have heard that you must capture the 0/A frame as the first frame for reverse telecining/advanced pulldown removal to work. Is this true. Even if so, the whole clip other than the first frame is still fine so, any ideas?

    Ive received an answer to this in another forum. It is due to the fact that cinema tools has no other field to combine with for the first frame depending on which of the 5 field sequence it started recording in. It is really no problem because it is only the very first frame that is affected.
