I have raid0 on 12 Seagate new 3TB sas drives and kernel version is 2.6.32SL6.1 version. The ext4 is mounted with barrier on, delalloc on/off has almost the same result. I ran fs_mark -F -t 10 -D 1000 -N 1000 -n 1000000 -s 40 -S 2 into 4 iterations(reported count of 40000000) and then power cycled the box. After the box came up, I ran fsck -f to check inconsistency. On ext4 FS 7.5TB and 16TB, I got no fsck error; but on 17TB, 21TB and 33TB, I got big chunk of fsck errors. My question is: is this known issue and any fix?
