DESCRIPTION

   dpm-modifypool modifies a disk pool definition.

   This command requires ADMIN privilege.

OPTIONS

   pool_name
          specifies  the  disk  pool   name.    It   must   be   at   most
          CA_MAXPOOLNAMELEN characters long.

   defsize
          specifies the default amount of space reserved for a file.  This
          is by default in bytes, but the number may  also  be  post-fixed
          with  'k',  'M'  or  'G'  for  kilobyte,  Megabyte  and Gigabyte
          respectively.

   def_lifetime
          specifies the default time a space or volatile file is  kept  in
          the system (in seconds).

   defpintime
          specifies  the  default  time a file is kept on a given disk (in
          seconds).

   gc_start_thresh
          specifies the minimum free space in the pool.  If the percentage
          of  free  space  goes below this value, the garbage collector is
          started.

   gc_stop_thresh
          specifies the percentage of free space in the pool  above  which
          the garbage collector is stopped.

   max_lifetime
          specifies  the  maximum time a space or volatile file is kept in
          the system (in seconds).

   maxpintime
          specifies the maximum time a file is kept on a  given  disk  (in
          seconds).

   pool_gids
          The  existing  list can be reset using a comma separated list of
          group gids, extended by prefixing the gid by  +  or  reduced  by
          prefixing the gid by -.  See examples.

   pool_groups
          The  existing  list can be reset using a comma separated list of
          group names, extended by prefixing the name by + or  reduced  by
          prefixing  the name by -.  The keyword "ALL" means non-dedicated
          pool.  See examples.

   retention_policy
          specifies the retention policy supported by the  disk  pool.  It
          can be R (for Replica), O (for Output) or C (for Custodial).

   space_type
          indicates  the  type of space supported in the disk pool. It can
          be V (for Volatile), D (for Durable), P (for Permanent) or - (to
          accept any type).

EXAMPLE

        dpm-modifypool --poolname Volatile --def_filesize 100M \
             --groups -dteam,ops,+atlas

EXIT STATUS

   This  program  returns  0  if the operation was successful or >0 if the
   operation failed.
