I have a SQL Server R2 cluster on Windows 2008 R2 boxes, and today i was to install SP3. I installed it without any errors and rebooted the passive node.
When i then try to failover to the passive node it fails. I get this from the Log
Log Name: Application Source: MSSQLSERVER Date: 2015-03-24 18:38:45 Event ID: 19019 Task Category: Failover Level: Error Keywords: Classic User: N/A Computer: computername.domain.se Description: [sqsrvres] OnlineThread: SQLClusterResourceWorkerWaitForCompletion failed (status 0) Event Xml: 19019 2 3 0x80000000000000 16109747 Application computername.domain.se [sqsrvres] OnlineThread: SQLClusterResourceWorkerWaitForCompletion failed (status 0) 4B4A0040010000000D0000005700460041004C0049005400450043004C00300031003400000000000000

If i failback to the unpatched node, i get the resorces online without problem. But the patched node just keep on failing.
