Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
AssignedTo: fs_ext4@kernel-bugs.osdl.org
ReportedBy: zakrzewskim@wp.pl
Regression: No
I'm getting ext4 errors in dmesg even if I unmount partition then make e4fsck
-fy -C0 /dev/md2.
I looks like this parition is mounted with no errors:
EXT4-fs (md2): mounted filesystem with ordered data mode. Opts:
usrjquota=aquota.user,grpjquota=aquota.group,usrquota,grpquota,jqfmt=vfsv0
then after few hours it shows itself:
EXT4-fs (md2): error count: 7
EXT4-fs (md2): initial error at 1354656587: ext4_mb_generate_buddy:736 EXT4-fs
(md2): last error at 1354664617: ext4_ext_split:929: inode 97911179
So far no other issues.
Disks are fine. SMART ok. RAM checked with memtest and ok.
Partition mounted like this:
/dev/md2 /home ext4
rw,noatime,nodiratime,usrjquota=aquota.user,grpjquota=aquota.group,usrquota,grpquota,jqfmt=vfsv0
0 0
/dev/md2 2,7T 1,8T 885G 68% /home
md2 : active raid1 sdd3[2] sdc3[0]
2914280100 blocks super 1.0 [2/2] [UU]
It happens only on 2x 3 TB RAID1 array.
