2009/09/1011:29:18 VCS WARNING V-16-20011-5508 (server1)CFSMount::online:Mount Error : UX:vxfsmount. vxfs:Warning: V-3-26144: conflicting suboptions: ioerror=mwdisable and cluster To resolve the issue:
Due to the fact that a CFS cluster is active-active, CFS mounted filesystems are online on all nodes.
For this example, review the following mount resource from an incorrectly setup main.cfcluster configuration file:
CFSMount cfs_mount ( MountPoint = "" BlockDevice ="/dev/vx/dsk//" MountOpt@server1 = "suid,largefiles,ioerror=mwdisable" MountOpt@server2 = "suid,largefiles,ioerror=mwdisable" MountOpt@server3 = "suid,largefiles,ioerror=mwdisable" ) In a scenario where connection to a SAN on one node is lost, the option"ioerror=mwdisable" will cause the volume to become disabled on all nodes.
Disabling the volume on the other cluster nodes which may still have SAN access would not be desirable, as this would cause an unnecessary outage.
The ClusterFile System software is aware of the conflicting options and sends warning messages logged in /var/VRTSvcs/log/engine_A.log.
The solution is to remove the "ioerror=mwdisable" option from the mount resource mountoptions.
