Thanks.
I addedd the following lines to the cib.xml
>drbd.add:
><master_slave id="ms-drbd0">

And then these for the filesystem:
<primitive class="ocf" provider="heartbeat" type="Filesystem" id="fs0">
<meta_attributes id="ma-fs0">
<attributes>
<nvpair name="target_role" id="ma-fs0-1" value="stopped"/>
</attributes>
</meta_attributes>
<instance_attributes id="ia-fs0">
<attributes>
<nvpair id="ia-fs0-1" name="fstype" value="ext3"/>
<nvpair id="ia-fs0-2" name="directory"
value="/usr/local/DATA"/>
<nvpair id="ia-fs0-3" name="device" value="/dev/drbd0"/>
</attributes>
</instance_attributes>
</primitive>
When I try to add the constraints (as in:
http://www.linux-ha.org/DRBD/HowTov2):
drbd.add3 file:
<rsc_order id="drbd0_before_fs0" from="fs0" action="start" to="ms-drbd0"
to_action="promote"/>
<rsc_colocation id="fs0_on_drbd0" to="ms-drbd0" to_role="master"
from="fs0" score="infinity"/>
cibadmin -C -V -o constraints -x drbd.add3
I receive the following error:
cibadmin[14401]: 2008/02/18_12:10:22 ERROR: parse_xml: Ignoring trailing
characters in XML input.
cibadmin[14401]: 2008/02/18_12:10:22 ERROR: parse_xml: Parsed 95
characters of a possible 190. Trailing text was: '<rsc_colocation id="'...
If I start only the drbd resource it works fine, when I try to start the
filesystem resource I receive an error about a not possible mount.
Can anyone help to sort this out?
TIA for help.
