OPTIONS

22       pool_name
23              specifies the disk pool name.  It must be  at  most  CA_MAXPOOL‐
24              NAMELEN characters long.
25
26       defsize
27              specifies the default amount of space reserved for a file.  This
28              is by default in bytes, but the number may  also  be  post-fixed
29              with 'k', 'M' or 'G' for kilobyte, Megabyte and Gigabyte respec‐
30              tively.
31
32       def_lifetime
33              specifies the default time a space or volatile file is  kept  in
34              the system (in seconds).
35
36       defpintime
37              specifies  the  default  time a file is kept on a given disk (in
38              seconds).
39
40       gc_start_thresh
41              specifies the minimum free space in the pool.  If the percentage
42              of  free  space  goes below this value, the garbage collector is
43              started.
44
45       gc_stop_thresh
46              specifies the percentage of free space in the pool  above  which
47              the garbage collector is stopped.
48
49       max_lifetime
50              specifies  the  maximum time a space or volatile file is kept in
51              the system (in seconds).
52
53       maxpintime
54              specifies the maximum time a file is kept on a  given  disk  (in
55              seconds).
56
57       pool_gids
58              The  existing  list can be reset using a comma separated list of
59              group gids, extended by prefixing the gid by  +  or  reduced  by
60              prefixing the gid by -.  See examples.
61
62       pool_groups
63              The  existing  list can be reset using a comma separated list of
64              group names, extended by prefixing the name by + or  reduced  by
65              prefixing  the name by -.  The keyword "ALL" means non-dedicated
66              pool.  See examples.
67
68       retention_policy
69              specifies the retention policy supported by the  disk  pool.  It
70              can be R (for Replica), O (for Output) or C (for Custodial).
71
72       space_type
73              indicates  the  type of space supported in the disk pool. It can
74              be V (for Volatile), D (for Durable), P (for Permanent) or - (to
75              accept any type).
76
