Subject: [PATCH 87/89] Specify nodes number when updating cluster nodes
|
|
Commit: 138a9e9bbe2622eafc90c976b82f3d84895dbebd
|
|
Patch-mainline: mdadm-4.1+
|
|
References: jsc#SLE-13700

|
|
Now it allows updating cluster nodes without specify --nodes. It can write superblock
|
|
with zero nodes. It can break the current cluster. Add this check to avoid this problem.
|
|
|
|
v2: It needs check c.update first to avoid NULL pointer reference
|
|
v3: Wol points the typo error
