There is a local root exploit for GPFS commands like mmlsquota, see

As a temporary workaround the setuid-flag has been removed from GPFS commands, disabling regular users from running e.g. mmlsquota. Running mmlsquota now throws a rather misleading error:

mmlsquota -u $USER --block-size auto max-home
Failed to connect to file system daemon: No such process
mmlsquota: GPFS is down on this node.
mmlsquota: Command failed. Examine previous error messages to determine cause.

That just means, that $USER is not privileged to run the command, not that there is something wrong with GPFS. It will be fixed with the next GPFS update on maxwell.
