I’m trying to setup a simple DRBD cluster using Ubuntu 14.04 LTS using
Pacemaker & Corosync. My problem is getting the resource to startup.
I’ve setup the DRBD aspect fine. Checking /proc/drbd I can see that my test
DRBD device is all synced and OK.
Following the examples from the “Clusters From Scratch” document, I built the
following cluster configuration:
property \
stonith-enabled="false" \
no-quorum-policy="stop" \
symmetric-cluster="false"
node ct1
node ct2
node ct3 attributes standby="on"
primitive drbd_disc0 ocf:linbit:drbd \
params drbd_resource="disc0"
primitive drbd_disc0_fs ocf:heartbeat:Filesystem \
params fstype="ext4" device="/dev/drbd0" directory="/replicated/disc0"
ms ms_drbd0 drbd_disc0 \
meta master-max="1" master-node-max="1" clone-max="2"
clone-node-max=“1” \
notify="true" target-role="Master"
colocation filesystem_with_disc inf: drbd_disc0_fs ms_drbd0:Master
ct1 & ct2 are the main DRBD servers, with ct3 being a witness server to avoid
split-brain problems.
When I look at the cluster status, I get:
crm(live)# status

Current DC: ct2 (739377523) - partition with quorum

Failed actions:

): not configured
What have I done wrong?
Thanks,
