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.
