I am doing some RAID scenarios on a single disc (testing purposes) on
RHEL4. I have some partitions as follows:
/dev/hda5 100M
/dev/hda6 200M
/dev/hda7 200M
/dev/hda8 200M
/dev/hda9 200M
I create a RAID 5 set with /dev/hda{5,6,7,8}. I fail/remove /dev/hda5
and add /dev/hda9, at which point I can grow the RAID. Running:
mdadm -G /dev/md0 -z max
Have you copied the data from hda5 to hda9 with dd? If i remember,
growing a RAID 5 that way is done by creating the missing stripes at
the end of each disks. If the array is already in degraded mode, I am
not sure if mdadm is able to recover from that.
