vserver export-policy cache flush

Flush the Export Caches

Availability: This command is available to cluster administrators at the admin privilege level.

Description​

The vserver export-policy cache flush command clears out the contents of the export policy caches for a Vserver. You might need to flush the caches to allow the changes to immediately take effect for your NFS clients because of:

  • A change to your export policy rules.

  • Modifying a host name record in a name server (i.e., local hosts or DNS).

  • Modifying a PTR record in a DNS server (i.e., reverse DNS lookup).

  • Modifying the entries in a netgroup in a name server (i.e., local netgroup, LDAP, or NIS).

  • Recovering from a network outage that resulted in a netgroup being partially expanded.

To flush the caches, you must specify the following items:

  • Vserver: either a specific Vserver or use "*" to flush all of them.

You can optionally specify the following items:

  • Node: if flushing the access cache, you can also specify which node to flush it on.

  • Cache to flush: by default all but showmount will be flushed.

Note that the showmount cache is not used to determine NFS client access and as such is only flushable explicitly.

Parameters​

-vserver <vserver name> - Vserver
This parameter specifies the name of the Vserver on which you want to flush the caches.
[-node <nodename>] - Node
This parameter specifies the node on which you want to flush the access cache.
[-cache {all|access|host|id|name|netgroup|showmount|ip}] - Cache Name
This parameter specifies the name of the cache which you want to flush. Possible values include the following:

  • all - All caches but showmount. This is the default.

  • access - The export-policy rules access cache.

  • host - The host name to IP cache.

  • id - The ID to credential cache.

  • ip - The IP to host name cache.

  • name - The name to ID cache.

  • netgroup - The netgroup cache.

  • showmount - The showmount caches.

Examples​

The following example flushes the access cache on a Vserver named vs0: 

cluster1::> vserver export-policy cache flush -vserver vs0 -cache access
