The rquotad protocol has been implemented as a service on the storage server. It functions as a read-only protocol and is only responsible for reporting information about user and group quotas. Quotas can be created, deleted, or modified through the Storage Management section of NAS Manager.

A UNIX/Linux NFS client can issue the quota command to retrieve information regarding quota usage of a user or group, based on their ID. The retrieved report contains block count, file count, quota limits on both, and other information (based on options invoked with the command). For accurate syntax, refer to the client's man pages, as implementation varies between client operating systems.

The server reports only Hard Limit quota information through rquotad. Three different quota limitations can be defined:
  • User and group quotas to limit space and file quantity for individuals and groups within a virtual volume.
  • User and group quotas to limit space and file quantity for individuals and groups within an entire file system.
  • Virtual volume quotas to limit space and file quantity by a virtual volume as a whole.
Note: rquotad reports quota usage information on explicitly defined quotas and automatically created (default) quotas. Default quota information will be reported if an explicit quota has not been defined.
The rquotad service can be configured to report quota information using one of two modes:
  • Restrictive mode. For the user or group specified in the client-side quota command, the rquotad service reports the quota information for the quota with the most constraints.
  • Matching mode. For the user or group specified in the client-side quota command, the rquotad service reports the quota information for the first quota that meets the parameters defined by the client-side quota command.
Note: If the rquotad service is disabled, all requests are rejected with an error code of "EPERM".
