Bug description:
# mdadm -Cv /dev/md0 --bitmap=clustered -l1 -n2 /dev/sdd /dev/sdb
--nodes=6 --assume-clean
# mdadm --grow /dev/md0 --bitmap=none
# mdadm --grow /dev/md0 --bitmap=clustered
-> cluster nodes would be changed to 4, here is my method to
resolve it.
# mdadm --grow /dev/md0 --bitmap=clustered --nodes=6
Patch:
Cluster nodes is set 4 as default when switch bitmap from
none to clustered under GROW mode, so add '--nodes'
option in GROW mode.
