[Pacemaker] Decreasing failover time when running DRBD+OCFS2+XEN in dual primary mode

[kamal kishi]

Hi All,

This might be a basic question but I'm not sure whats taking time for
failover switching.
Hope anyone can figure it out.

Scenario -
Pacemaker running DRBD(Dual primary mode)+OCFS2+XEN for Virtual windows
machine

Pacemaker startup starts -
DRBD -> OCFS2 -> XEN
Lets consider under Server1  - DRBD, OCFS2(clone) and XEN are started

Server2 - DRBD, OCFS2(clone) are started

Now if Server1 power is OFF

The XEN resource which was running under Server1 should be failed over to
Server2.

In my case, its taking almost 90 to 110 seconds to do this.

Can anyone suggest me ways to reduce it to within 30 to 40 seconds

My pacemaker configuration is -
crm configure
property no-quorum-policy=ignore
property stonith-enabled=false
property default-resource-stickiness=1000

primitive resDRBDr1 ocf:linbit:drbd \
params drbd_resource="r0" \
op start interval="0" timeout="240s" \
op stop interval="0" timeout="100s" \
op monitor interval="20s" role="Master" timeout="240s" \
op monitor interval="30s" role="Slave" timeout="240s" \
meta migration-threshold="3" failure-timeout="60s"
primitive resOCFS2r1 ocf:heartbeat:Filesystem \
params device="/dev/drbd/by-res/r0" directory="/cluster" fstype="ocfs2" \
op monitor interval="10s" timeout="60s" \
op start interval="0" timeout="90s" \
op stop interval="0" timeout="60s" \
meta migration-threshold="3" failure-timeout="60s"
primitive resXen1 ocf:heartbeat:Xen \
params xmfile="/home/cluster/xen/win7.cfg" name="xenwin7" \
op monitor interval="20s" timeout="60s" \
op start interval="0" timeout="90s" \
op stop interval="0" timeout="60s" \
op migrate_from interval="0" timeout="120s" \
op migrate_to interval="0" timeout="120s" \
meta allow-migrate="true" target-role="started"

ms msDRBDr1 resDRBDr1 \
meta notify="true" master-max="2" interleave="true" target-role="Started"
clone cloOCFS2r1 resOCFS2r1 \
meta interleave="true" ordered="true" target-role="Started"

colocation colOCFS12-with-DRBDrMaster inf: cloOCFS2r1 msDRBDr1:Master
colocation colXen-with-OCFSr1 inf: resXen1 cloOCFS2r1
order ordDRBD-before-OCFSr1 inf: msDRBDr1:promote cloOCFS2r1:start
order ordOCFS2r1-before-Xen1 inf: cloOCFS2r1:start resXen1:start

commit
bye
