Comment 9 for bug 1811795

Hi,
Here test steps:
1. Create IMSM Container:
    mdadm -CR imsm0 -e imsm -n 2 /dev/sd[bc]
2. Create IMSM level 0 Array:
    mdadm -CR vol0 -l 0 -n 2 /dev/sd[bc]
3. Wait for resync to complete
   mdadm --wait /dev/md/vol0
4. Read /proc/mdstat and check /dev/md/ directory
   cat /proc/mdstat
   ls /dev/md/
5. Fail one disk incrementaly (simulate device disappearing from system)
   mdadm -If sdc
6. Check mdstat file and /dev/md/
   cat /proc/mdstat
   ls /dev/md/
Result:
   After disk fail [5] raid 0 array should disappear from mdstat, link /dev/md/imsm0 should exist.

The issue is fixed in PPA.

Thanks,
Mariusz
