Hi,
What is the crm shell command to move drbd master to a different
node?
take a look at this
http://www.mail-archive.com/pacemaker@oss.clusterlabs.org/msg06300.html

Wow, not the friendliest command I would say. Maybe "move" command can
be enhanced to provide something similar?
Thanks,
Vadym
The _crm resource move/migrate <rsc>_ provides/creates the location
constraint within the crm shell.
In the example I gave:
_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
/
The warning message appears in the console after executing the command
in the crm shell, running a crm configure show reveals the following:
/location cli-standby-ms_drbd_storage ms_drbd_storage \
rule $id="cli-standby-rule-ms_drbd_storage" -inf: #uname eq cluster1
/
The example in the UEL above has been done manually to (probably)
provide an advisory placement constraint, the one set by _crm resource
move <rsc>_ is a mandatory placement constraint.

Dan
