-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi!
I've been using JFS version 1.1.1 for a long time with an updated SuSE 8.1 kernel 2.4.19-329 and just had a bad loss of newly created files. I used gimp (1.2) a little too much and it created a swapfile in the JFS filesystem with up to 2GB, then it hung and could not continue. I shut down all programs, as the machine under X was not usable anymore, but did not reboot, but just restarted my X session and everything seemed fine. Alas, I didn't realized one day later that it wasn't. When I tried a plain 'sync' to flush all buffers to disk, that command hung. I could neither kill it nor have it finish. I then tried to unmount the JFS, but that responded with 'busy' as the 'sync' commands ( I tried syncing a couple of times) where still accessing the disk, I presume. Then I used 'umount -l' on the mount and that at least showed the disk unmounted. Then I tried to reboot but that didn't work either. I guess it hung when syncing the filesystems, i.e. my JFS that was stuck. So a hard reboot (via kernel Sysrq) was necessary. I'm sitting on top of a IBM ServeRAID controller with hw-raid level 1 with 2 disks for / and hw-raid level 1 with 2 disks for /home, the latter in a logical volume. After the reboot everything seemed fine, except for the following, which is the main reason for my mail. After the reboot I realized that many files that I created within the last several hours have been lost, i.e. are there but show size 0, even though the fsck after reboot and another manual one afterwards didn't report any problems. Luckily, I didn't lose any important data files, but just ones that could be recreated. Now I am very worried about this happening again. Is there a known issue with creating large files, as I presume that was the reason for the errors in the end? Can I do anything to help track down the problem, to avoid the problem? Thanks for anything!
