    [SOLVED] lost home partition

    Hi all i just installed ubuntu 8.04 in my pc and i wanted to use an old home partition i had in the past.My problem is that when i try to mount it i get this error :
    Code:
    # mount -t reiserfs /dev/sda2 /mnt
    mount: wrong fs type, bad option, bad superblock on /dev/sda2,
           missing codepage or helper program, or other error
           In some cases useful info is found in syslog - try
           dmesg | tail  or so
    Is there a way to at least save some data from the partition?

    First you need to use sudo in front of the command as it can only be used with root permission. Have a look at this to read all about sudo
    However as this is your /home partition you need to have a look at this or reinstall and use manual partitioning when you get to that part and make sure you set sda2 as /home, but also make sure you don't format it in the install procedure.

    Re: lost home partition

    The command i run it with root permission:
    Code:
    root@:~# mount -t reiserfs /dev/sda2 /mnt
    mount: wrong fs type, bad option, bad superblock on /dev/sda2,
           missing codepage or helper program, or other error
           In some cases useful info is found in syslog - try
           dmesg | tail  or so
    Now i wonder if it is possible to mount the partition and recover some data from it.

    Re: lost home partition

    Well i tried with
    Code:
    root@:~# mount -t ext3 /dev/sda2 /mnt
    mount: wrong fs type, bad option, bad superblock on /dev/sda2,
           missing codepage or helper program, or other error
           In some cases useful info is found in syslog - try
           dmesg | tail  or so
    but still no luck .Is there a way to fix this?

    Re: lost home partition

    You know what I apologize i miss read my own output I thought my reiserfs was showing an ID of 5 but that's my extended partion, the reiserfs is show 83 just like my ext3 partions. So I was wrong. Maybe open up gparted and run a check on it,
    Code:
    sudo reiserfsck --yes --fix-fixable /dev/sda2
    would be the cli equivalent of that. That's about as far as I could help.

    Re: lost home partition

    I managed to sole this executing the following :
    Code:
    fsck.reiserfs  /dev/sda2
    Code:
    reiserfsck --rebuild-tree /dev/sda2
    Code:
    mount -t reiserfs /dev/sda2 /mnt/
