System Administration Commands                                       nfsref(8)



NAME
       nfsref - NFS referral utility

SYNOPSIS
       nfsref [-t svc_type] add path location [location ...]


       nfsref [-t svc_type] remove path


       nfsref [-t svc_type] lookup path

DESCRIPTION
       The  nfsref  command manages NFS Version 4 referrals, which are server-
       side pointers used to redirect clients to actual locations of file sys‐
       tems.  Referrals  are  based  on  reparse  points  (see reparsed(8) and
       libreparse(3LIB)). The path arguments in  all  forms  of  the  synopsis
       refer to the path to the reparse point symbolic link. This command cur‐
       rently implements one service type: nfs-basic,  which  embeds  location
       information within the reparse point.


       The  first form of the command, nfsref add, creates a referral pointing
       to the specified locations. If a reparse point does not exist,  one  is
       created. If it does exist, NFS service data is added or replaces exist‐
       ing NFS service data. Each location has a host:/path format.  The  path
       can  contain spaces, which must be escaped to ensure proper shell pars‐
       ing.


       The second form of the command, nfsref remove, removes an NFS referral.
       It  removes  NFS  service  data  from  the specified reparse point, and
       removes the reparse point if there are no other types of  service  data
       present.


       The third form of the command, nfsref lookup, displays the locations to
       which the specified NFS referral points.

OPTIONS
       The following options are supported:

       -t svc_type

           Specify a service type. Currently, only nfs-basic is supported.


EXAMPLES
       Example 1 Adding an NFS Referral



       The following command creates  an  NFS  referral  at  the  server  path
       /pool/home/bob, pointing to the resource homeserver:/homepool/bob.


         # nfsref add /pool/home/bob homeserver:/homepool/bob
         Created reparse point /pool/home/bob

         # nfsref lookup /pool/home/bob
         /pool/home/bob points to: homeserver:/homepool/bob



       Example 2 Removing an NFS Referral



       The  following  command  removes  an  NFS  referral  at the server path
       /pool/home/bob.


         # nfsref remove /pool/home/bob
         Removed svc_type 'nfs-basic' from /pool/home/bob
