27[1mOPTIONS[0m
28       [4mpool_name[0m
29              specifies the disk pool name.  It must be  at  most
30CA_MAXPOOL‐
31              NAMELEN characters long.
32
33       [4mdefsize[0m
34              specifies the default amount of space reserved  for
35a file.  This
36              is  by  default  in bytes, but the number may  also
37be  post‐fixed
38              with ’k’, ’M’ or ’G’ for kilobyte, Megabyte and Gi‐
39gabyte respec‐
40              tively.
41
42       [4mdef_lifetime[0m
43              specifies the default time a space or volatile file
44is  kept  in
45              the system (in seconds).
46
47       [4mdefpintime[0m
48              specifies  the  default  time a file is kept  on  a
49given disk (in
50              seconds).
51
52       [4mgc_start_thresh[0m
53              specifies  the  minimum free space in the pool.  If
54the percentage
55              of  free  space  goes below this value, the garbage
56collector is
57              started. Default is 0.
58
59       [4mgc_stop_thresh[0m
60              specifies  the percentage of free space in the pool
61above  which
62              the garbage collector is stopped. Default is 0.
63
64       [4mmax_lifetime[0m
65              specifies  the  maximum time a  space  or  volatile
66file is kept in
67              the system (in seconds).
68
69       [4mmaxpintime[0m
70              specifies  the  maximum  time  a  file is kept on a
71given  disk  (in
72              seconds).
73
74       [4mpool_gids[0m
75              if not zero, the disk pool is  restricted  to  this
76comma separated
77              list of group gids.
78
79       [4mpool_groups[0m
80              if  set  and not "ALL", the disk pool is restricted
81to this  comma
82              separated list of group names.
83
84       [4mretention_policy[0m
85              specifies  the  retention  policy supported by  the
86disk pool. It
87              can  be  [1mR [22m(for Replica), [1mO [22m(for Out‐
88put)  or  [1mC  [22m(for  Custodial).
89              Default is [1mR[22m.
90
91       [4mspace_type[0m
92              indicates  the  type of space supported in the disk
93pool. It can
94              be [1mV [22m(for Volatile), [1mD [22m(for Durable),
95[1mP [22m(for Permanent) or [1m‐ [22m(to
96              accept any type).  The latter is the default.
