Symptoms

  • De /nsr_share/nsr/logs/daemon.raw registreert de volgende fout tijdens het opstarten van de service:
73248 01/31/2023 12:57:48 PM  5 5 0 926312256 966299 0 nwrhelnodef.emclab.local nsrd NSR critical Can't start nsrd because /nsr/res (/nsr) is local, and NetWorker is configured as a cluster server. Use cluster manager to check NetWorker service status.

  • Het knooppunt kan de clusterbronnen zien met: lcmap
root@NWrhelNodeF:~# lcmap
type: NSR_CLU_TYPE;
clu_type: NSR_LC_TYPE;
interface version: 1.0;

type: NSR_CLU_VIRTHOST;
hostname: 192.168.25.28;

Cause

Het IP-adres wordt niet omgezet in de naam die wordt gebruikt door de NetWorker clusterconfiguratie: 
root@NWrhelNodeF:~# nslookup 192.168.25.28
** server can't find 28.25.168.192.in-addr.arpa: NXDOMAIN
Het IP-adres moet worden omgezet naar de NSR_SERVERHOST waarde in het bestand /usr/lib/ocf/resource.d/EMC_NetWorker/Server: 
root@NWrhelNodeF:~# cat /usr/lib/ocf/resource.d/EMC_NetWorker/Server | grep SERVERHOST
                    echo "q" | nsradmin -s ${NSR_SERVERHOST} -i - > /dev/null 2>&1
                        echo "q" | nsradmin -s ${NSR_SERVERHOST} -i - > /dev/null 2>&1
NSR_SERVERHOST=NWrhelClusD.emclab.local
Deze waarde wordt ingesteld bij het uitvoeren van het script /usr/sbin/networker.cluster.

Resolution

Naamresolutie voor de VIP oplossen. Dit kan worden gecorrigeerd door ad-admin in DNS-configuratie of met behulp van bestandsvermeldingen /etc/hosts op elk knooppunt dat betrokken is bij het cluster. 
root@NWrhelNodeF:~# nslookup 192.168.25.28
28.25.168.192.in-addr.arpa      name = NWrhelClusD.emclab.local.

Zodra de naam correct is opgelost, kunnen NetWorker-services worden gestart:

root@NWrhelNodeF:~# pcs resource cleanup nws
Cleaned up fs on NWrhelNodeF.emclab.local
Cleaned up fs on NWrhelNodeE.emclab.local
Cleaned up ip on NWrhelNodeF.emclab.local
Cleaned up ip on NWrhelNodeE.emclab.local
Cleaned up nws on NWrhelNodeF.emclab.local
Cleaned up nws on NWrhelNodeE.emclab.local

root@NWrhelNodeF:~# pcs resource
  * Resource Group: NW_group:

    * ip        (ocf::heartbeat:IPaddr):         Started NWrhelNodeF.emclab.local
    * nws       (ocf::EMC_NetWorker:Server):     Started NWrhelNodeF.emclab.local
