/dev/md0 reporting wrong amount of free space
Here's dmesg excerpt:
[ 270.766123] EXT4-fs error (device md0): ext4_mb_generate_buddy:756: group 13198, block bitmap and bg descriptor inconsistent: 3210 vs 32768 free clusters
[ 272.796055] JBD2: Spotted dirty metadata buffer (dev = md0, blocknr = 0). There's a risk of filesystem corruption in case of system crash.
[ 272.796717] JBD2: Spotted dirty metadata buffer (dev = md0, blocknr = 0). There's a risk of filesystem corruption in case of system crash.
[ 310.236009] EXT4-fs (md0): error count since last fsck: 55302
[ 310.236019] EXT4-fs (md0): initial error at time 1440956525: ext4_mb_generate_buddy:756
[ 310.236022] EXT4-fs (md0): last error at time 1441004249: ext4_mb_generate_buddy:756
here's also something that might help (md0 is comprised of /dev/sda1 and /dev/sdb1:
$ cd /sys/block/md0/md
$ cat component_size
0
$ grep . dev-sd*/size
dev-sda1/size:1953511936
dev-sdb1/size:1953511936
Other than that, is seems all files are available and correct. /dev/md0 is mdadm RAID0 (stripping) array. Anybody knows how to fix this?
