CVAFFINITY(1)                                                                                  CVAFFINITY(1)



NAME
       cvaffinity - Set an affinity type

SYNOPSIS
       cvaffinity -s key filename

       cvaffinity -l filename

       cvaffinity -d filename





DESCRIPTION
       cvaffinity can be used to set an affinity for a specific storage pool on a file or directory, or list
       the current affinity.  An affinity is created in a storage pool through the volume configuration (see
       snfs_config(5).)   It  is  a  name,  up to eight (8) characters, describing a special media type. Use
       cvadmin(1) to see what affinity sets are assigned to the configured storage pools.

       If the affinity does not exist for any of the storage pools, then the allocation will  occur  on  the
       non-exclusive storage pool.  If there is no non-exclusive storage pool, an ENOSPC is returned.

USAGE
       -s key key is the Affinity Key to associate with the file or directory and is defined as a the affin-ity affinity
              ity keyword in the storage pool section of the file  system  configuration.  Use  the  program
              'cvadmin'  to  see  the Affinity Keys active in this file system.  For files with an Affinity,
              new blocks allocated to that file are placed on a storage pool with  the  specified  Affinity.
              For directories with an Affinity new files created in that directory inherit the Affinity from
              the directory.


       -l     This option says to just list the affinity for the specified file and exit.


       -d     This option says to delete the affinity from the specified file or directory, if one exists.


       filename
              Specifies any file or directory on the targeted volume.   When  the  -k  option  (set  session
              affinity)  is  specified,  or  no  other option is specified, the filename option is used as a
              read-only reference handle in order to access the volume.  When the -s, -d, or -l options  are
              used, the filename option specifies the file or directory operated on.

EXAMPLES
       List the affinity on the file /usr/clips/foo.

          rock # cvaffinity -l /usr/clips/foo

       Set this file or directory to use the storage pool that has the jmfn8 affinity type.

          rock # cvaffinity -s jmfn8 /usr/clips/filename

       Remove the affinity from the /usr/clips/mydir, if one is currently assigned.

          rock # cvaffinity -d /usr/clips/mydir
