DPM-ADDPOOL(1)						    DPM Administrator Commands						    DPM-ADDPOOL(1)

NAME

       dpm-addpool - define a new disk pool

SYNOPSIS

       dpm-addpool  --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-addpool defines a new disk pool.

       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. Default is 0.

       gc_stop_thresh
	      specifies the percentage of free space in the pool above which the garbage collector is stopped. Default is 0.

       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
	      if not zero, the disk pool is restricted to this comma separated list of group gids.

       pool_groups
	      if set and not "ALL", the disk pool is restricted to this comma separated list of group names.

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

       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).  The latter is the default.

EXAMPLE

	    dpm-addpool --poolname Volatile --def_filesize 200M --s_type V

EXIT STATUS

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