Unable to determine whether a file system is mounted

Certain GPFS file system commands cannot be performed when the file system in question is mounted.

In certain failure situations, GPFS cannot determine whether the file system in question is mounted or not, and so cannot perform the requested command. In such cases, message 6027-1996 (Command was unable to determine whether file system fileSystem is mounted) is issued.

If you encounter this message, perform problem determination, resolve the problem, and reissue the command. If you cannot determine or resolve the problem, you may be able to successfully run the command by first shutting down the GPFS daemon on all nodes of the cluster (using mmshutdown -a), thus ensuring that the file system is not mounted.
