Unable to mount /home partition

When I booted up this morning I got this message:

mount: wrong fs type, bad option, bad superblock on /dev/sdb4,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg | tail produced this:

my fstab looks like this:

NOTES:

  • I can mount this partition when I boot up using the arch install disk (log in as root: mount /dev/sdb4 /home)

  • I'm uncertain what I did, this is the first time in a long time that I've restarted/shut down my computer, many things have happened since then.

Re: Unable to mount /home partition

Have you tried an fsck.ext4 on it?

Re: Unable to mount /home partition

I think you should look higher in dmesg's output to get the error message from the beginning...

Re: Unable to mount /home partition

This looks like the error I get when the OS is trying to mount an ext4 partition and doesn't know about it. Not sure why Arch would forget about ext4 though.

Re: Unable to mount /home partition

@ stqn
how would I go about looking higher (I'm unfamiliar with the command)

@ jdarnold
I don't think it's the same problem as yours. Arch mounts the ext4 root partition well enough.

Thanks

Re: Unable to mount /home partition

Just type "dmesg" and scroll up if necessary...

Re: Unable to mount /home partition

thanks

is there anything I should be on the lookout for?

One thing I did notice was that the output said that the partition had an invalid journal inode. Could this be the cause? is there a way to fix it?

Isn't your root partition formatted in ext3?
I think you should check out jdarnold's case too.

Re: Unable to mount /home partition

Apart from the other good suggestions - an idea - try and change your fstab for you home to ex3 and try and mount it.

Also check all entries of your pacman.log for the last time you booted up properly (2011-03-10?).

Oh, and do a pacman -Syu of course smile

Re: Unable to mount /home partition

Doesn't mount at boot, manual mount still works...
Have you changed/added/expanded partitions?  I've noticed UUIDs can change if the partition structure is fiddled with.

Re: Unable to mount /home partition

If you can mount /home as root once the system is booted, try doing this:
1. mount it like this, i.e. mount /dev/sdb4 /home
2. type "mount" in terminal, and paste the output here

There might be an error in your fstab configuration, and the "mount /dev/sdb4 /home" ignores your fstab, so it mounts it correctly.

Well, the owner has gone for ten days, no point posting any more. Right?

Yeah, could be... sorry, overlooked that fact.

Perhaps he solved it...
