    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
