Hi all
I'm trying to fix ddf test errors which we see recently. But I see
this error: "Failed to connect to control socket". I tried with an
imsm array with loop devices and the imsm array also has this problem.
(Note, this problem doesn't appear with real devices which system
supports imsm)
mdadm -CR /dev/md/imsm -e imsm -n 4 /dev/loop8 /dev/loop9 /dev/loop10
/dev/loop11
mdadm -CR /dev/md/vol1 -n 4 -l 10 /dev/loop8 /dev/loop9 /dev/loop10
/dev/loop11 -z 10000
mdadm: Creating array inside imsm container /dev/md127
mdadm: array /dev/md/vol1 started.
mdadm: Failed to connect to control socket.
