Good day guys !
I'm implementing fencing in my two node cluster with this detail:
- fence_vmware_soap
- PostgreSql release 10.X
- CentOS 7.X
As far as I know, to create the resources, I can use two different ways:
- Create only one resource for both nodes, following this way:
# pcs -f stonith_cfg stonith create fence_nodes \
fence_vmware_soap \
ipaddr=<VM_IP> \
ssl_insecure=1 \
login="<VM_user>" \
passwd="<VM_passwd>" \
action=reboot \
pcmk_host_list="node_01,node_02" \
power_wait=3 op monitor interval=60s
- Create two different resources, one for each node, following this way:
# pcs -f stonith_cfg stonith create fence_node_01 \
fence_vmware_soap \
ipaddr=<VM_IP> \
ssl_insecure=1 \
login="<VM_user>" \
passwd="<VM_passwd>" \
action=reboot \
pcmk_host_list="node_01" \
power_wait=3 op monitor interval=60s
# pcs -f stonith_cfg stonith create fence_node_02 \
fence_vmware_soap \
ipaddr=<VM_IP> \
ssl_insecure=1 \
login="<VM_user>" \
passwd="<VM_passwd>" \
action=reboot \
pcmk_host_list="node_02" \
power_wait=3 op monitor interval=60s
With this method I understand I will have to add some constraints, etc.
Said this, my questions are:
- Which are the differences among them ? (if any).
- Is there any recommended option and why ?
