Ubuntu 9.10 won't boot UNEXPECTED INCONSISTENCY

[billlyum]

A few days after successfully upgrading to 9.10 I turned on my computer and the the boot screen started a filesystem check. It then crashed and the following DOS screen came up:

/dev/sda5 contains a filesystem with errors, check forced.
Filesystem checks are in progress (ESC to cancel)
/dev/sda5: Inodes that were part of a corrupted orphan linked list found
/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY (ie: -a or -p options)
mountall: fsck/[427] terminated with status 4
mountall: filesystem has errors: /
init: mountall main process (419) terminated with status 3
Mount of filesystem Failed
A maintenance shell will now be started
CTRL D will terminate this shell & retry
root@IBM:~#_

If I press CTRL D the following comes up:

mountall start/starting
fsck from util-linux-ng 2.16
/dev/sda5 contains filesystem with errors. check forced
swapon: /dev/disk/by-uuid/f6100565-d920-4d6f-b253-b1bd2f5650ec: swapon failed: device or resource busy

I'm hoping I can somehow fix this and get back to business as usual w/ my previously working 9.10 setup. Worst case scenario I'd like to save my files, wipe that partition and install a fresh 9.10.

I don't know how to accomplish either of the above so any direct help or pointing me in the right direction would be really appreciated.

bump

[Cheesemill]

You're going to have to give more details, error messages etc.

Also please note it's forum policy to only bump after 24 hours

[billlyum]

Sorry about the premature bump. I edited the original post to show the exact output from DOS. Hopefully this helps.

[billlyum]

Can I get a bump now?

Try running fsck again, if you can.

[ejetzer]

I have the exact same problem. I'm gonna try using fsck.

EDIT:After runing fsck, I can boot my computer without problems, and hav gone back to the usual little problems (random freeze for everything but the mouse, and random full boot)
Thanks!

[billlyum]

fsck worked like a charm. It basically asked me if I wanted to fix a bunch of stuff, all to which I say yes, and upon reboot everything worked perfectly.

Thanks for the tips!

sorry for posting on solved topic. thx you for saving my ubuntu laptop

[billlyum]

So after working for a couple days I'm back to having the same issue I initially had. It started with certain folders and applications not opening and then upon restart the OS crashed w/ the same type of errors as in the original post.

This time FSCK found similar problems but with different #'s (ie: Inode 221201 was part of the orphaned inode list. FIXED. but in the first fsck it was a different inode #)

Any thoughts?
