Hello List,
I am currently trying to add a third node only for giving a quorum a to
the cluster in case a servicing node fails. But oviously I can't get it
right.
The third node is forced to standby and I put a location constraint just
like described in:
http://clusterlabs.org/wiki/DRBD_HowTo_1.0#Specifying_the_nodes_where_the_DRBD_RA_can_be_run
this is from my config:
node $id="beafcd74-f991-4e77-ae82-a8ad0a76f8a1" storage-test-d
node $id="d001b7e3-5c97-4913-8fe7-764fcf67416f" storage-voter \
attributes standby="on"
node $id="deb75c11-7d06-4b6d-ae7b-f64eead63a54" storage-test-c
primitive drbd_testdata1 ocf:linbit:drbd \
params drbd_resource="testdata1" \
op monitor interval="29s" role="Master" \
op monitor interval="31s" role="Slave"
primitive st-storage-test-c stonith:null \
params hostlist="storage-test-c"
primitive st-storage-test-d stonith:null \
params hostlist="storage-test-d"
ms ms_drbd_testdata1 drbd_testdata1 \
meta master-max="1" master-node-max="1" clone-max="2"
clone-node-max="1" notify="true"
location l-st-node1 st-storage-test-c -inf: storage-test-c
location l-st-node2 st-storage-test-d -inf: storage-test-d
location l_ms_drbd_testdata1 ms_drbd_testdata1 \
rule $id="l_ms_drbd_testdata1-rule" -inf: #uname ne
storage-test-c and #uname ne storage-test-d
property $id="cib-bootstrap-options" \
dc-version="1.1.7-ee0730e13d124c3d58f00016c3376a1de5323cff" \
cluster-infrastructure="Heartbeat" \
expected-quorum-votes="2" \
last-lrm-refresh="1411727659"
So there are three nodes storage-test-c, storage-test-d and
storage-voter. The resource is being started correctly on storage-test-c
and storage-test-d but pacemaker keeps monitoring the resource on
storage-voter complaining it is "not installed" which is correct as this
node will never hold any resource actually. It just has the same network
connections as the other ones and should be helping to decide if a node
is actually down or just isolated.
This is the message from crm status:
Failed actions:
drbd_testdata1:0_monitor_0 (node=storage-voter, call=9, rc=5,
status=complete): not installed
Can anyone give me a hint how to solve this? As said storage-voter will
never run any resource although it would be nive if it could trigger
stonith actions anyway.
Thank you all in advance,
best regards, Felix
