Resolving full condition for GPFS file system

Use this procedure when the management GUI reports a critical error when a file
system is 100% full.
About this task
You must have root access to perform this procedure.
Note: If you use GPFS snapshots, the file system locks when it reaches 100%
utilization.
Procedure
To resolve the full condition for the file system, perform the following steps:
1. Review the contents of the GPFS file system.

v If the file system has snapshots, remove the oldest snapshot after verifying
that it is no longer needed. Continue to remove the snapshots from oldest to
newest until the level of free space that you want is achieved.
v If no snapshots exist, perform the following steps:
a. Run the mmdf command to determine what storage pool is out of space.
b. Remove files to free up storage.
c. If the mmdf command output shows that there is space in free fragments,
run the mmdefragfs command to combine the fragments into full blocks.
Note: You can run the GPFS defrag command while the file systems are
mounted. However, for better results, unmount the GPFS file system
before performing the defragmentation operation.
