Subject: RE: RAID-1 problem after device removal
Hi,
When I SCSI-remove a drive from a RAID-1 partition I see the RAID
partition correctly marked failed (F).
However, all write attempts after this are quietly failing, even though the
file system (XFS) and LVM are not reporting any errors.
In other words.
cp * TEST_FOLDER; echo "scsi remove-single-device 1 0 1 0" >
/proc/scsi/scsi; touch TEST_FILE
The files from TEST_FOLDER and TEST_FILE appear on the file system, but when
I reboot they have disappeared! Note that I do not see this issue with a
RAID-5 AND does not occur on RAID-1 Superblock version 1.2.
So I only see this with RAID-1 Superblock version 0.9.
I have tried kernel 3.2.32 and 3.2.37 and the both show this behavior.
The same test succeeds on 2.6. I am committed to 3.2.x so I cannot move
further upstream.
Am I doing something illegal?
Does anybody recognize this?
Any suggestions how I should proceed?
Thanks,
Barry
