NAME

       dpm-modifypool - modify a disk pool definition

SYNOPSIS

       dpm-modifypool  --poolname  pool_name  [  --def_filesize  defsize  ]  [	--def_lifetime	def_lifetime  ]  [  --def_pintime  defpintime  ] [
       --gc_start_thresh perc ] [ --gc_stop_thresh perc ] [ --gid pool_gids ] [ --group pool_groups ] [ --help ] [ --max_lifetime max_lifetime ] [
       --max_pintime maxpintime ] [ --ret_policy retention_policy ] [ --s_type space_type ]

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 prefix-
	      ing 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  pre-
	      fixing 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.
