From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6 Description of problem: The system has problem with root (/) filesystem on RAID1 (mirror) partition. After about one week uptime I found that the filesystem was remounted read-only and fsck showed lots of errors. This is quite strange, that it happened only to root filesystem, but not to /var and /home (which are on separate partitions on the same disks). The problem happened twice in two weeks, for the first time fsck -f /dev/md0 corrected the filesystem, the second time whole filesystem went to lost+found. The disks are ok (checked with smartctl and badblocks non-destructive r-w). In /var/log/messages I found: kernel: EXT3-fs error (device md0): ext3_new_inode: reserved inode or inode > inodes count - block_group = 0, inode=1 kernel: Aborting journal on device md0 kernel: EXT3-fs error (device md0) in ext3_new_inode: IO failure kernel: EXT3-fs error (device md0) in ext3_create: IO failure kernel: ext3_abort called kernel: EXT3-fs error (device md0): ext3_journal_start_sb: Detected aborted journal Version-Release number of selected component (if applicable): kernel-2.6.12-1.1398_FC4 How reproducible: Sometimes Steps to Reproduce: 1. Install fresh FC4 on RAID1 partition (created during installation). /dev/md0 - / /dev/md1 - swap /dev/md2 - /var /dev/md3 - /home 2. Let the system work for a week (mailserver with antivirus, web server). Not too busy. Actual Results: Found the system half-working - some tasks were unable to complete becouse of read-only /tmp The filesystem was corrupted. Expected Results: The system shoud work without corrupting filesystem. Additional info: The system is 1xPIII 1.4 GHz, 3 x 36GB SCSI disks, Intel SDS2 motherboard
Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks.
Seems like a bug was addressed in kernel 2.6.12-1.1447_FC4. The system works 17 days without a crash, whereas with the previous kernel it would crash within a week.
