problem with jfs root partition

A short while back, I crashed arch (found some bug that froze everything) and ever since I've been unable to load arch as it mounts my jfs filesystem as read-only.

I've tried to repair it from my debian sid system (also jfs) following the arch wiki instructions on what to do in this situation. Running fsck.jfs on the partition checks it, but it doesn't take longer as predicted from a potentially damaged log.

Any suggestions for what I can do to repair it from here?

Re: problem with jfs root partition

Did you run

fsck.jfs -p /dev/sdx

or

fsck.jfs -f /dev/sdx

what happened?
Maybe more details will bring you more help.

Re: problem with jfs root partition

perhaps I should add that I have no problem mounting, reading and writing to the partition from my debian system.

Re: problem with jfs root partition

If the Arch root partition is ok and you can use it from Debian, check if there is a file named "forcefsck" there. Delete it.

I found only a 'fsck' file. tried removing that to no avail.
