Message-ID: <20081206155317.GL30807@vanheusden.com> Date: Sat, 6 Dec 2008 16:53:17 +0100 From: Folkert van Heusden <folkert@...heusden.com> To: Randolf Pohl <randolf.pohl@....de> Subject: Re: [2.6.27] filesystem (ext3) corruption (access beyond end) Ok I ran several disk-intensive jobs (git clone, kernel build, apt-get dist-upgrade) but none of those could trigger any bugs. BUT, running my http://vanheusden.com/pyk/ script, I definately can trigger the problem: [85202.195563] rtc0: alarms up to one month, y3k, hpet irqs [85204.035802] journal_bmap: journal block not found at offset 2060 on dm-0 [85204.035818] Aborting journal on device dm-0.

[92499.263515] EXT3-fs error (device dm-2): ext3_journal_start_sb: Detected aborted journal [92499.263543] Remounting filesystem read-only [93531.419902] EXT3-fs error (device dm-0): htree_dirblock_to_tree: bad entry in directory #24568: rec_len % 4 != 0 - offset=0, inode=4098364138, rec_len=59542, name_len=76 Very odd since the script only rmmod/insmods modules and trying to rmmod for example ext3-module shouldn';t be a problem since it is in use.
