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. Default is 0.

retention_policy

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

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). The latter is the default.
