I'm testing a PowerShell Disaster Recovery script and trying to fail over to an off-site AG DR (asynch) replica with this command
ALTER AVAILABILITY GROUP [MyAG] FORCE_FAILOVER_ALLOW_DATA_LOSS
On several clusters this works fine but on a couple of other ones it usually fails (but not always) with the error:
Failed to move a Windows Server Failover Clustering (WSFC) group to the local node (Error code 5023). The WSFC service may not be running or may not be accessible in its current state, or the specified cluster group or node handle is invalid. For information about this error code, see "System Error Codes" in the Windows Development documentation.
Failed to designate the local availability replica of availability group 'MyAG' as the primary replica. The operation encountered SQL Server error 41018 and has been terminated. Check the preceding error and the SQL Server error log for more details about the error and corrective actions.
We have to force the quorum simulating the situation where the async DR replica can't communicate with the other replicas: https://docs.microsoft.com/en-us/sql/sql-server/failover-clusters/windows/force-a-wsfc-cluster-to-start-without-a-quorum?view=sql-server-2017
A comparison of the clusters that work vs. those that don't with
Get-ClusterGroup doesn't reveal any major differences.
This failover has worked successfully on some clusters but fails 99% of the time on two of the clusters. It has worked on these two clusters, but rarely. One of the common issues I found from a Google search is permissions for
NT Authority\System (see https://dataginger.com/2014/10/28/sql-server-failed-to-bring-availability-group-availability-group-name-online/), which I confirmed it has.
I ran a trace and see the same errors and no other clues in the trace.
If nothing turns up I may have to open a Microsoft ticket to engage their support.
Thanks for your help!
