group gids, extended by prefixing the gid by + or reduced by
prefixing the gid by -. See examples.

[4mpool_groups[0m
The existing list can be reset using a comma separated list of

can be [1mR [22m(for Replica), [1mO [22m(for Output) or [1mC [22m(for Custodial).

[4mspace_type[0m
indicates the type of space supported in the disk pool. It can
