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
accesscache, you can also specify which node to flush it on. -
Cache to flush: by default all but
showmountwill 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
accesscache. [-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 butshowmount. This is the default. -

host- The host name to IP cache. -

ip- The IP to host name cache. -
name- The name to ID cache. -
netgroup- The netgroup cache. -
