I have configured AlwaysOn in external mode between two CentOS 7 VMs. When manual failover happens, primary goes to resolving state. It never turns to secondary and secondary is always in secondary state
-- All nodes (linux01 and linux02)
sudo pcs property set stonith-enabled=false
sudo pcs property set no-quorum-policy=ignore
sudo pcs property set cluster-recheck-interval=2min
-- resource configuration
sudo pcs resource create sqlag ocf:mssql:ag ag_name=haag master notify=true meta failure-timeout=30s
sudo pcs resource create vip_ip ocf:heartbeat:IPaddr2 ip=192.168.52.62 cidr_netmask=24 op monitor interval=30s
sudo pcs constraint colocation add vip_ip sqlag-master INFINITY with-rsc-role=Master
sudo pcs constraint order promote sqlag-master then start vip_ip
sudo pcs cluster start --all
-- linux01 is primary move to linux02
sudo pcs resource move sqlag-master linux02 --master
linux01 in resolving; linux02 in secondary. Hangs; no response in SSMS.
