DESCRIPTION


dpm-modifypool modifies a disk pool definition.

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.

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

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
The existing list can be reset using a comma separated list of group gids, extended
by prefixing the gid by + or reduced by prefixing the gid by -. See examples.

pool_groups
The existing list can be reset using a comma separated list of group names,
extended by prefixing the name by + or reduced by prefixing the name by -. The
keyword "ALL" means non-dedicated pool. See examples.

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

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).

EXAMPLE


dpm-modifypool --poolname Volatile --def_filesize 100M \
--groups -dteam,ops,+atlas
