None of the Interfaces is attached, and the management network uses interface
ethX0. If any ethX1 port cable is unplugged, the health center displays a failure
because no network is attached to an interface, which causes the system to monitor
all ports.

EFSSG1000I
The command completed successfully. EthX0 is attached to a network, and the
management network uses ethX0. If any ethX1 port cable is unplugged, the health
center does not display a failure because ethX1 is used neither by an attached
network nor by the management network.

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.
You must have root access to perform this procedure.
Note: If you use GPFS snapshots, the file system locks when it reaches 100%
utilization.
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.
