Security

You must have root authority to run the mmquotaoff command.

GPFS must be running on the node from which the mmquotaoff command is issued.

In an SP environment, verify the authentication method set for SP security services:

1. If your authentication method is set to compatibility, Kerberos authentication is required. Issue the k4init command.
2. If your authentication method is set to DCE, dce_login authentication is required.
3. If your authentication method is set to NONE/std, there must be an entry in the /etc/sysctl.mmcmd.acl file on every node in the nodeset for the root user at every other node in the nodeset.
