Date: Sun, 16 Jan 2011 15:03:57 +0100 From: Stuart Pook <slp4725@...k.it> To: linux-ext4@...r.kernel.org Subject: error ext4_mb_generate_buddy:726 & add_dirent_to_buf:1272 after online resize hi I'm getting these errors on my home filesystem [ 5147.616006] EXT4-fs (dm-28): error count: 11 [ 5147.616888] EXT4-fs (dm-28): initial error at 1295177566: ext4_mb_generate_buddy:726 [ 5147.617827] EXT4-fs (dm-28): last error at 1295177566: add_dirent_to_buf:1272: inode 262145: block 1048578 I have done a fsck -f and that didn't make them stop. The errors started a few minutes after I did an online resize of my filesystem. To resize the filesystem I did something like this: lvextend --size +14G vg_root/stuart cryptsetup resize _dev_dm_21 resize2fs /dev/mapper/_dev_dm_21 It took me a couple of attemps to find the correct arguments for the "cryptsetup resize" but I don't think I broke anything. When I saw the errors from "mv" at 12:32:46 I unmounted the filesystem and did a fsck. That corrected some errors but I'm still getting "ext4_mb_generate_buddy:726" and "add_dirent_to_buf:1272" errors. The filesystem in question is an encrypted partition on top of a lvm partition on a SSD. thanks Stuart :; uname -a Linux kooka 2.6.37-trunk-amd64 #1 SMP Thu Jan 6 14:13:28 UTC 2011 x86_64 GNU/Linux :; fsck.ext4 -V e2fsck 1.41.12 (17-May-2010) Using EXT2FS Library version 1.41.12, 17-May-2010 :; grep 'EXT4-fs.*error' /var/log/syslog Jan 16 12:32:46 kooka kernel: : [2379819.157537] EXT4-fs error (device dm-27): ext4_mb_generate_buddy:726: group 3232766 blocks in bitmap, 32254 in gd Jan 16 12:32:46 kooka kernel: : [2379819.157840] EXT4-fs error (device dm-27): add_dirent_to_buf:1272: inode #262145: block 1048578: comm mv: bad entry in directory: inode out of bounds -
