I have a Linux Cluster based on Pacemaker(v1.1.18-11) and corosync(v2.4.3-2) setup on Centos 7.2 It is a Two nodes setup with nodes= DBHA (master) and DBFAILOVER (slave)
I have a resource Postgresql9 which uses this Resource agent: pgsql with slight variation
I am using the standard documentation to setup Postgres replication : PgSQL_Replicated_Cluster
After doing all step for master it still was not becoming master. Following error was shown in /var/log/cluster/corosync.log
Could not map name=dbha to a UUID
After debugging for a bit I found out that following command returns above error:
/usr/sbin/crm_attribute -l reboot -N "dbha" -n "Postgresql9-status" -v "STOP"
Where Nodename is calucated by:
NODENAME=$(ocf_local_nodename | tr '[A-Z]' '[a-z]')
where ocf_local_nodename() is from ocf-shellfuncs:
ocf_local_nodename() {
# use crm_node -n for pacemaker > 1.1.8
which pacemakerd > /dev/null 2>&1
if [ $? -eq 0 ]; then
local version=$(pacemakerd -$ | grep "Pacemaker .*" | awk '{ print $2 }')
version=$(echo $version | awk -F- '{ print $1 }')
ocf_version_cmp "$version" "1.1.8"
if [ $? -eq 2 ]; then
which crm_node > /dev/null 2>&1
if [ $? -eq 0 ]; then
crm_node -n
return
fi
fi
fi
# otherwise use uname -n
uname -n
}
I tried running both commands crm_node -n
and uname -n
on DBHA node both return following:
DBHA
Also in cibadmin:
<nodes>
<node id="2" uname="DBHA">...
When I Manually run crm_attribute command to set attribute it again returns the same error.
Here is the CIB: CIB
Please help
Thanks in advance
NOTE: We have multiple setups on different OS(CENTOS (6.5,6.7,7.2,7.5) Redhat(7.5). We never faced this problem before. Also, the Capital letter (or small letters) in node names never caused any problems before.
