Hello,
I really searched for the answer before posting : ).
I have a pacemaker setup + corosync + drbd in Active/Passive mode running
in 2 node cluster on Ubuntu 12.04.3.
Everything works fine and on node failure the services are taken care of by
the other node (THANKS guys!), well the problem is that I've noticed, that
once the failed node comes back alive, the pacemaker restarts the
postgresql and virtual IP and that takes around 4-7 seconds (but keeps it
on the same node as I wanted, what's the point? :) ). Is this really
necessary, or I've messed up something in the configuration?
My pacemaker config:
node drpg-01 attributes standby="off"
node drpg-02 attributes standby="off"
primitive drbd_pg ocf:linbit:drbd \
params drbd_resource="drpg" \
op monitor interval="15" \
op start interval="0" timeout="240" \
op stop interval="0" timeout="120"
primitive pg_fs ocf:heartbeat:Filesystem \
params device="/dev/drbd/by-res/drpg" directory="/db/pgdata"
options="noatime,nodiratime" fstype="xfs" \
op start interval="0" timeout="60" \

primitive pg_lsb lsb:postgresql \

primitive pg_vip ocf:heartbeat:IPaddr2 \
params ip="10.34.2.60" iflabel="pgvip" \
