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
