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
