Dear Maintainer,
When growing RAID1 two-device array to three device RAID5:
# mdadm --manage /dev/md2 --add /dev/sdc4
mdadm: added /dev/sde4
# mdadm --grow /dev/md2 --level=raid5 --raid-devices=3
mdadm: level of /dev/md2 changed to raid5
mdadm: Need to backup 128K of critical section..
If during this operation two disks marked failed with mdadm or being
disconnected, array goes to FAILED state,
but reshape operation not interrupted. This leads to situation when array can't
be stopped and system can't
recovery without reboot.
# mdadm --manage /dev/md2 --fail /dev/sde4
mdadm: set /dev/sdb4 faulty in /dev/md2
# mdadm --manage /dev/md2 --fail /dev/sdb4
mdadm: set /dev/sdc4 faulty in /dev/md2
# mdadm -D /dev/md2
/dev/md2:
