6027-645 Attention: mmcommon getEFOptions fileSystem failed. Checking fileName.
Explanation
The names of the disks in a file system were not found
in the cached GPFS™ system data,
therefore an attempt will be made to get the information from the
operating system's file system database.
User response
If the command fails, see File system fails to mount. A common cause for such
errors is lack of space in /var.
