What is the crm shell command to move drbd master to a different node?

<pre wrap=""># crm resource help migrate
Migrate a resource to a different node. If node is left out, the
resource is migrated by creating a constraint which prevents it from
running on the current node. Additionally, you may specify a
lifetime for the constraint---once it expires, the location
constraint will no longer be active.
Usage:
...............
migrate <rsc> [<node>] [<lifetime>]
crm resource migrate ms_drbd_storage
WARNING: Creating rsc_location constraint 'cli-standby-ms_drbd_storage' with a score of -INFINITY for resource ms_drbd_storage on cluster1.
This will prevent ms_drbd_storage from running on cluster1 until the constraint is removed using the 'crm_resource -U' command or manually with cibadmin
This will be the case even if cluster1 is the last node in the cluster
This message can be disabled with -Q
This also made me to remind that I was wondering, is there a way to
demote one instance of multi-master ms resource away from particular
node (forcibly switch it to a slave state on that node). I didn't find
the answer too. Is it possible with crm shell?
Same as above, just specify the node in the command.

Have you actually tried it? This command doesn't work for this case.

To be honest, no, I actually don't think it's viable since in a
multi-master architecture you have a one-to-one relationship on the
DRBD side. There's a thread related to this over on the DRBD mailing
list, still no reply yet, might want to check it out over the next
couple of days for progress. <br>
