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.
