Hello Sandeep,

Do you receive any errors/warnings when performing the Start-ClusterNode -CQ?

When a cluster node is in quarantine it means the following:

  • The node is no longer allowed to join the cluster for a fixed time period (default: 2 hours)­
  • This action prevents flapping nodes from negatively impacting other nodes and the overall cluster health
  • By default, a node is quarantined, if it ungracefully leaves the cluster, three times within an hour
  • VMs hosted by the node are gracefully drained once quarantined
  • No more than 25% of nodes can be quarantined at any given time

Do you see clues in the FailoverCluster event log?

Best regards,
Leon

Hello.

We are having a similar issue.

An event had occurred to cause quarantine on 4 separate AG Clusters 2016.

The problem was cleared.

I used Failover Cluster Manager console to "start cluster service" under "more actions" on the quarantined node.

The nodes came up green and the ag databases are synching  again however the status for the quarantine node still remains "quarantine".

Start-ClusterNode -clearquarantine results with state="up"

But Get-ClusterNode returns StatusInformation="Quarantined"   still (instead of normal)

The 2 hour quarantine period is many hours past also.

I see no other issues. How do we clear this status?

Any help is appreciated.

Thanks

Mark

Thank you Mark!

Running "Start-ClusterNode -ClearQuarantine" on the node helped our situation.

I have the exact same issue, did you get any fix for this, if yes, can you share what worked with you?

Thanks.
