Hi,
What is the crm shell command to move drbd master to a different node?
# 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.

Dan
Thank you,
