- I'm having the following problem on a raid6 md volume consisting og
16 1TB Seagtes SSHD's. ( using kernel 3.15.3 or 3.14.0 ) mdadm is 3.3.
- every time I run a fsck.ext4 I will get the exact same errors (
...short read ). Forcing a repair on the md0 volume shows no errors
and completes without problems. All disks are active and the volume is
not degraded, still I can't get rid of the short errors on those 16
blocks and when the filesystem is mounted the read errors will come up
from time to time as they are probably in use.
- If I try to read those blocks with DD ( dd if=/dev/md0 of=test.txt
seek=458227712 count=6 bs=4096 ) it will instantly create a 1.8T file
but the file doesn't appear to have nothing on it ( and the file
doesn't take the 1.8T on disk as the disk is much smaller )
- this started happening after having a three disk failure. I
recovered from that failure by recreating the array with the
non-failed 13 disks plus the last failed one ( events didn't differ
much ). I then readed the other disks. The failed disks are all
physically good, tested them with hdat2 and they don't have read/write
errors so I reused them. I don't know why they failed, maybe some
incompatibility with SSHD's and the LSI HBA controller..
