<div>Wow, not the friendliest command I would say. Maybe "move"
command can be enhanced to provide something similar?</div>

The <u>crm resource move/migrate <rsc></u> provides/creates the
location constraint within the crm shell. <br>
<br>
In the example I gave:<br>
<br>
<u>crm resource migrate ms_drbd_storage</u><br>
<br>
<i>WARNING: Creating rsc_location constraint
'cli-standby-ms_drbd_storage' with a score of -INFINITY for resource
ms_drbd_storage on cluster1.<br>
<b> 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<br>
This will be the case even if cluster1 is the last node in the
cluster<br>
</b> This message can be disabled with -Q<br>
</i><br>
The warning message appears in the console after executing the command
in the crm shell, running a crm configure show reveals the following:<br>
<br>
<i>location cli-standby-ms_drbd_storage ms_drbd_storage \<br>
rule $id="cli-standby-rule-ms_drbd_storage" -inf: #uname eq
cluster1<br>
</i><br>
The example in the UEL above has been done manually to (probably)
provide an advisory placement constraint, the one set by <u>crm
resource move <rsc></u> is a mandatory placement constraint.<br>
