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.
