wrong fs type, bad option, bad superblock on /dev/hda3

[Daan]

Hi. I can't mount my new ext3 partition (which was first ntfs with Windows XP on it):

schmauck:/mnt/hda3# mount /dev/hda3
mount: wrong fs type, bad option, bad superblock on /dev/hda3,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

schmauck:/mnt/hda3# dmesg | tail
EXT3-fs: mounted filesystem with ordered data mode.

Here's my /etc/fstab:

# /etc/fstab: static file system information.

And here's some other command output:

What's wrong?

/dev/hda3 /mnt/hda3 ext3 defaults,errors=remount-ro 0 1

Replace it with

/dev/hda3	/mnt/hda3	ext3    defaults 0 0

Save file and reboot machine. Check /mnt/hda3 folder.

In case it doesn't work, post the output of fdisk -l command. You must have root privileges to execute fdisk command.

That helped, thanks Casper!
How would I proceed to make this my new /home. Copy the contents of my current home to /mnt/hda3, and then delete the contents of my current home, change fstab to mount /dev/hda3 at /home and reboot? Use a live cd?

Hi Daan,

Yes copy / delete should work. Although I'd be more tempted to move /home to something like home.old and create a new /home mount point instead of deleting it straight away.

No need to reboot though, unmount /mnt/hda3 and remount it.

# umount /dev/hda3
# mount -a

Not sure if the remount option would work, but you could give it a try:

#mount -o remount /dev/hda3

[devils casper]

You have to take are of permissions of all the files in /home folder. Use copy -a command to preserver permissions. Dont delete contents before checking new /home.

[matonb]

copy -a

Well spotted that man
