dpm-addpool defines a new disk pool.
This command requires ADMIN privilege.
- 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.
