Thank Dragan! It works!
Seems it's mdadm itself create the link rather than do through kernel,
which gave me a little trouble. :D
Hi Dragan,
One more question if you don't mind:
When you do
mdadm --stop /dev/md/device-123
Would mdadm remove the broken link file /dev/md/device-123 automatically?
I found I have to remove the link file manually later...
You stopped the array. You might want to assemble it once again saying
mdadm --assemble /dev/md/device-123 /dev/loop0 /dev/loop1
Then, it would just create a new /dev/md*number* and create the link
with /dev/md/device-123.
This is my logical thought, havent looked at the mdadm code though to
confirm this.
Regards
Anugraha
