    Unhappy REISERFS - file recovery!!


    Hello,

    I've tried search but cannot find how to fix this problem.
    AND IT'S VERY VERY IMPORTANT TO FIX THIS ASAP!!

    User has requested recovery deleted folder on /HOME with 2 or more important files.
    Here You are more details:

    1. Filesystems used:
    root@serwer:~# cat /etc/fstab
    /dev/sda1 swap swap defaults 0 0
    /dev/sda2 / reiserfs defaults 1 1
    /dev/sda3 /home reiserfs defaults 1 2/dev/cdrom /mnt/cdrom auto noauto,owner,ro 0 0
    /dev/fd0 /mnt/floppy auto noauto,owner 0 0
    devpts /dev/pts devpts gid=5,mode=620 0 0
    proc /proc proc defaults 0 0
    2. System/Linux ver.:
    root@serwer:~# uname -arvmio
    Linux serwer 2.4.31 #21 Sun Jun 5 19:19:51 PDT 2005 i686 unknown unknown GNU/Linux

    Hardware is HP Proliant ML310 - with the RAID array.

    3. Space (before recovery):
    was about 85 GB used on /HOME
    4. Space (after recovery - now):
    root@serwer:/home# df -h
    Filesystem Size Used Avail Use% Mounted on
    /dev/sda2 9.4G 2.7G 6.7G 29% /
    /dev/sda3 140G 105G 35G 76% /home

    Ok, so I've found solution here:
    ReiserFS undelete/data recovery HOWTO : Sounds From The Dungeon

    REISERFSCK has finished job (I have full log file - 5,1 MB) and found many files and moved to /HOME/LOST+FOUND.

    I didn't make any copy of this partition before, becouse I didn't have any so big disk.

    But there is problem now - many of files just dissapeared or are broken.
    I need Your help (( I have to fix this today, these files are very important for this company

    Well.. It was professional hardware SCSI hard drive failure.. no RAID unfortunately..
    So that's the reason of reconstructing tree process error.

    One advice for everyone: MAKE A BACKUP..

    EDIT:

    error message:
    dd read error: /dev/sda3 input/output error - which means sda3 device is broken (bad sector or something like that)

    Hi, Tomek_Teneg... sorry you had to answer your own question, but thanks for reporting back with the solution. That's very good advice you've given that all should heed, but few do so. Luckily for me, I've been backing up out of habit for years, now.

    Do post again should you have any other issues.

    and the second advice:

    DO NOT use reiserfs filesystem for servers.. use ext2/ext3 (the best) or journal instead..
    Data from this SCSI hard drive from this server is going to be recovered by 3rd company which can cost a lot of $$$..

    And the best option is RAID on 1 or 5 level.. either: software or hardware solution.
