reassign 425534 linux-2.6 2.6.18.dfsg.1-12 found 425534 2.6.18.dfsg.1-12etch2 retitle 425534 linux-2.6: ext3 filesystem corruption thanks
Hello, today I got an error in my ext3 root-fs very similar to the ones described earlier. 1) During boot hda1 reached maximal mount count and was checked. 2) e2fsck reports: /dev/hda1: Inode 53916 has illegal blocks /dev/hda1: UNEXPECTED INCONSISTENCY, RUN fsck MANUALLY 3) I then reboot into Knoppix, and start e2fsck. It shows now error on this filesystem. The superblock time error was only because the clock was wrong under knoppix. [EMAIL PROTECTED] e2fsck -yf /dev/hda1 e2fsck 1.39-WIP (09-Apr-2006) Superblock last write time is in the future. Fix? yes Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/hda1: ***** FILE SYSTEM WAS MODIFIED ***** /dev/hda1: 26298/124672 files (0.7% non-contiguous), 133789/248999 blocks 4) During the e2fsck run the output from dumpe2fs -h /dev/hda1 changed from: Filesystem state: clean with errors to Filesystem state: clean 5) After that the System booted without problems!! Because the Error occurs in different kernel packages I reassign it to the source package linux-2.6 and adjust the version numbers. In the meantime I write a small bash script that extracts a statistic how often this problem occurs with different kernel images from my log files. The script is attached, the logfiles are all from the same machine. Maybe the bug is fixed in Package 2.6.21-1-k7 Version 2.6.21-4. I will report after a few more tests. ---------------------------------------------- Kernel : 2.6.21-1-k7.*2.6.21-4 ---------------------------------------------- Days with this kernel booted (counted): 11 (Jun 22 until Jul 9 ) Reboots with this kernel in total (counted): 12 Reboots with EXT3 corruption (counted): 0 % Errorfree days (roughly) / reboots : 100% / 100% ---------------------------------------------- Kernel : 2.6.18-5-486.*2.6.18.dfsg.1-13 ---------------------------------------------- Days with this kernel booted (counted): 2 (Jul 9 until Jul 10 ) Reboots with this kernel in total (counted): 2 Reboots with EXT3 corruption (counted): 0 % Errorfree days (roughly) / reboots : 100% / 100% ---------------------------------------------- Kernel : 2.6.18-4-486.*2.6.18.dfsg.1-12 ---------------------------------------------- Days with this kernel booted (counted): 3 (Jul 10 until Jul 12 ) Reboots with this kernel in total (counted): 3 Reboots with EXT3 corruption (counted): 1 % Errorfree days (roughly) / reboots : 66% / 66% ---------------------------------------------- Kernel : 2.6.18-4-k7.*2.6.18.dfsg.1-12etch2 ---------------------------------------------- Days with this kernel booted (counted): 19 (May 18 until Jun 15 ) Reboots with this kernel in total (counted): 48 Reboots with EXT3 corruption (counted): 12 % Errorfree days (roughly) / reboots : 36% / 75% ---------------------------------------------- Kernel : 2.6.16.52 ---------------------------------------------- Days with this kernel booted (counted): 10 (Jun 13 until Jun 22 ) Reboots with this kernel in total (counted): 18 Reboots with EXT3 corruption (counted): 1 % Errorfree days (roughly) / reboots : 90% / 94% ---------------------------------------------- Kernel : 2.6.8-3-k7 ---------------------------------------------- Days with this kernel booted (counted): 37 (Apr 2 until May 18 ) Reboots with this kernel in total (counted): 51 Reboots with EXT3 corruption (counted): 0 % Errorfree days (roughly) / reboots : 100% / 100% Regards, Martin
