Hi
Given up on the clone resources, seems like there is no way to place the clones
onto nodes, so I have fallen back onto this
# Create ybrp ip address
pcs resource create ybrpip ocf:heartbeat:IPaddr2 params ip=10.32.21.20
cidr_netmask=24 nic=eth0 clusterip_hash=sourceip-sourceport \
op start interval="0s" timeout="60s" on-fail=restart \
op monitor interval="5s" timeout="20s" on-fail=restart \
op stop interval="0s" timeout="60s" \
pcs resource meta ybrpip
stickiness=100,migration-threshold=3,failure-timeout=600s
# Create status
pcs resource create ybrpstat ocf:yb:proxy op \
op start interval="10s" timeout="60s" on-fail=restart \
op monitor interval="5s" timeout="20s" on-fail=restart \
op stop interval="10s" timeout="60s" \
pcs resource meta ybrpstat stickiness=100
# clone it it
pcs resource clone ybrpstat globally-unique=false clone-max=2 clone-node-max=1
pcs constraint colocation add ybrpip ybrpstat-clone INFINITY
pcs constraint order ybrpstat-clone then ybrpip
Questions on this one are
If a service fails a monitor will the above make pacemaker restart the service
and check again ie recoverable error ?
