[ClusterLabs] SAP HANA monitor fails - Error performing operation: No such device or address

[Aj Revelino]

Hello All,
I've a 2 node SAP Hana cluster (hanapodb1 and hanapodb2). Pacemaker
monitors the data replication between the primary and the secondary node.
The issue is that crm status shows that everything is okay but the system
log shows the following error log.


*pacemaker-controld[3582]:  notice:
hanapopdb1-rsc_SAPHana_HPN_HDB00_monitor_60000:195 [ Error performing
operation: No such device or address]*
I am unable to identify the cause of the error message and resolve it

And due to the above, the data replication between the 2 nodes is recorded
as failed (SFAIL) . Pls see the excerpt from the CIB below:

 <node_state id="2" in_ccm="true" crmd="online"
crm-debug-origin="do_update_resource" uname="zhanapopdb2" join="member"
expected="member">
      <transient_attributes id="2">
        <instance_attributes id="status-2">
         * <nvpair id="status-2-hana_hpn_clone_state"
name="hana_hpn_clone_state" value="WAITING4PRIM"/>*
          <nvpair id="status-2-hana_hpn_version" name="hana_hpn_version"
value="2.00.056.00.1624618329"/>
          <nvpair id="status-2-master-rsc_SAPHana_HPN_HDB00"
name="master-rsc_SAPHana_HPN_HDB00" value="-INFINITY"/>
          *<nvpair id="status-2-hana_hpn_sync_state"
name="hana_hpn_sync_state" value="SFAIL"/>*
          <nvpair id="status-2-hana_hpn_roles" name="hana_hpn_roles"
value="4:S:master1:master:worker:master"/>
        </instance_attributes>
      </transient_attributes>

Pacemaker is able to failover the resources from the primary to the
secondary but they all fail back to the primary, the moment I clean up the
failure in the primary node.
I deleted and recreated the entire configuration and reconfigured the hana
data replication but it hasn't helped.
