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
