We have been observing issues with our file Cluster (Windows Server 2012 R2 Std Clustered with 2 Nodes) where File Server getsunresponsive for SMB access request event id 30809 in Microsoft-Windows-SMBClient/Connectivity is observedand when we try to failover the role clustered disks fail to get offline with an error in event id 1069 Cluster resource ' Disk Name' of type 'Physical Disk' in clustered role 'Role Name' failed, we have to force fully reboot the node which faces this issue. It works properly for a week and again we get the same issue, this happens with all the disks in different file server roles.
