    Cannot mount reformatted partition


    Hi,

    Running PCLinuxOS 2009.
    I had a partition formatted with ReiserFS.
    I was trying to create a large file (a clone of a VirtualBox
    .vdi file) and it kept stopping me at 2GB,
    so I decided to reformat with ext3.

    a) I deleted or moved all data
    b) sudo mkfs -V -t ext3 /dev/sda11
    c) sudo e2label /dev/sda11 VDIBKP

    This appeared to have worked:
    $ sudo blkid /dev/sda11
    /dev/sda11: LABEL="VDIBKP" UUID="f80616fa-147b-4810-aa6d-3b7c236a4cfb" SEC_TYPE="ext2" TYPE="ext3"

    However, when I try to mount the disk in konqueror,
    I get this pop up message:
    mount: wrong fs type, bad option, bad superblock on /dev/sda11, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

    Here is output from dmesg:
    ReiserFS: sda11: found reiserfs format "3.5" with standard journal
    ReiserFS: sda11: using ordered data mode

    Something seems to still think there is ReiserFS on that disk!
    But why?

    In cli I can only mount as root, but that DOES seem to work:
    $ mount /dev/sda11 /mnt/temp
    mount: only root can do that
    $ sudo mount /dev/sda11 /mnt/temp
    $ mount
    <snip other disks>
    /dev/sda11 on /mnt/temp type ext3 (rw)

    I hope I have put enough information for someone to see what my mistake is!

    Thanks,
    Shimon

    P.S. I got a suggestion that the partition might be marked as ReiserFS in fstab.
    Unfortunately that is not the case (it would be too easy, right?). It turns out
    that I had removed this partition from the fstab, (and commented out its lines)
    *months* ago, when I moved my personal data to a different partition.
    (At the time I also changed all of the mounts to be UUID based).

    $ grep sda11 /etc/fstab
    # Entry for /home/shimon - /dev/sda11 :
    # /dev/sda11 /home/shimon reiserfs defaults 0 0

    $ ls -al /etc/fstab
    -rw-r--r-- 1 root root 1582 Dec 30 17:23 /etc/fstab

    Thank you!

    I think it is normal that only root can mount partitions,
    unless the options in fstab say different. If you create
    the line in fstab, and identify it as EXT3, and give users
    permission to mount, you will be OK.
    As for the messages in dmesg, perhaps it is how the
    partition is flagged in the MBR. Issue the command
    fdisk -l to see your partitions listed.

    That is true of the command line "mount", but Konqueror allows me as a user to mount any partition (except this one which fails).
    The partitions listed in my /etc/fstab are only the ones I want mounted automatically at boot.
