Subject: [PATCH] Add '--nodes' option in GROW mode
Date: Tue, 22 Mar 2016 19:44:32 +0800 [thread overview]
Message-ID: <56F13020.8020900@suse.com> (raw)
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.
