IP addresses, IP wildcards, hostnames, hostname wildcards, and netgroups are supported. Defines an NFS client. This is a symbolic name of a client used to reference it in the resource tree. This is NOT the same thing as the target option. Client Name This is either a hostname, a wildcard (IP address or hostname based), or a netgroup to which defining a host or hosts to export to. Target Hostname, Wildcard, or Netgroup This is the path to export to the target. This field is generally left blank, as it inherits the path from the parent export. Path to Export File system ID inherited from the parent nfsexport/ clusterfs/fs resource. Putting fsid in the options field will override this. File system ID Defines a list of options for this particular client. See 'man 5 exports' for a list of available options. Export Options Allows recovery of this NFS client (default = 1) if it disappears from the export list. If set to 0, the service will be restarted. This is useful to help preserve export ordering. Allow recovery Service this NFS export belongs to. Used for caching exports on a per-service basis. Service Name On systems with large numbers of exports, a performance problem in the exportfs command can cause inordinately long status check times for services with lots of mounted NFS clients. This occurs because exportfs does DNS queries on all clients in the export list. Setting this option to '1' will enable caching of the export list returned from the exportfs command on a per-service basis. The cache will last for 30 seconds before expiring instead of being generated each time an nfsclient resource is called.
