Hi Team,

I keep getting this alert very often twice in a Day from OP manager

"Cluster resource 'File Share Witness' "\\fileshare name" in clustered service or application 'Cluster Group' failed."

Started recently after a DR upgrade on all of the systems 

DAG setup 

5 in active and 4 in passive 

Node and file share majority setup

I can see the fileshare and the alternate fileshare is accessible . The Cname has permission on the fileshare.

There is no issues with the DAG IP as well all are reachable and assigned correctly with the right IPS and  subnets

exchange 2010 

I checked the following things

1) Ran Get-DatabaseAvailabiltyGroup and im not able to find any issues 

2)Ran Get-MailboxDatabaseCopyStatus and i dont have any unhealthy copies

3) I'm able to perform a manual failover to my DR site without any issues , however not sure about the automatic failover

My DAG keeps showing red all the times in the OP manager which i suspect definitely there is some issues with the automatic Failover.

I noticed 1 thing

The NIC binding  is not in correct order in the DR site. May be this is causing the issue ?

When i run Get-ClusterGroup and Get-ClusterResource i can see all the resources are online without any issues 

I can see only these 2 events in the cluster logs  only for my DR servers 

The Cluster service failed to bring clustered service or application 'Cluster Group' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.

File share witness resource 'File Share Witness (\\fileshare)' failed to arbitrate for the file share '\\fileshare'. Please ensure that file share '\\fileshare' exists and is accessible by the cluster.

Any help towards the same is much appre

Hi,

For your question, please check the value of Pending Timeout, make sure it allows enough time for the associated application or service to start. The default setting is 60 muniters before administrator intervention is taken or the resource can be brought online. More details about it, pleease refer to below belog: http://blogs.technet.com/b/timmcmic/archive/2009/01/22/exchange-2007-sp1-ccr-windows-2008-clusters-file-share-witness-fsw-failures.aspx

Also, go to the server which hosting this alert File Witness Share, right click file share  and select Properties, switch to Share Permission and ensure you have added correctly permission, expecial local administrators group, Exchange Trusted Subsystem.

Thanks
