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.
