We were getting errors thrown by an OST. /var/log/messages contained a lot of these: 2010-11-28T17:05:34-05:00 umfs06.aglt2.org kernel: [2102640.735927] LDISKFS-fs error (device sdk): ldiskfs_mb_check_ondisk_bitmap: on-disk bitmap for group 639corrupted: 440 blocks free in bitmap, 439 - in gd
So, I turned off (most) access to the disk via lctl (we have a LOT of client machines, some were missed) and got problems. Had to use the alternate superblock to e2fsck the disk. When back online, I still saw similar messages. Updated to e2fsprogs 1.41.12 as suggested elsewhere. Repeated e2fsck. Still seeing these. Users report some files corrupted, coming up with bad md5sum.... Any other thoughts on what to do about this problem?
