Cluster node 'XYZ' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
Have you checked all network hardware to make sure there are no issues here. Last time I had a failover on one of my clusters someone had made a VLAN change to the port on the switch servicing the active node!

2.) Event ID: 1049Cluster IP address resource 'SQL IP Address 1 (XYZ)' cannot be brought online because a duplicate IP address '10.9.8.113' was detected on the network. Please ensure all IP addresses are unique.
This means what it says, who assigns IP addresses in your enterprise, get them to confirm the IP for your clustered instance! Take the virtual IP offline and then try to ping it to see if it still replies!

Have you tried running CHKDSK on these disks as the message suggests?
