Solaris Cluster Cannot Mount Shared Filesystem and Shows "Trying an overlay mount" and "is already mounted" (Doc ID 1003633.1)

Last updated on AUGUST 04, 2021

Applies to:

Solaris Cluster - Version 3.0 to 4.4 [Release 3.0 to 4.4]
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)

Symptoms

It was attempted to failover a resource group to the second node in the Solaris Cluster. The data services could not start on the second node because it could not mount the HA shared filesystems because the filesystems were either already mounted, busy or had exceeded the allowable number of mount points.


On the node trying to bring up the data services:



The 'fuser' command found no active processes on this mount point.  No one was in the directory and the filesystems were not already mounted on this node.  Tried removing the directory and recreating the directory mount point.  Then the filesystems would successfully mount.

When we rebooted, the filesystems could no longer be mounted, having the same problems as above.
