Usage:
|
||
|
|
$0 [--zpool=<name>] [--what=<item>]
|
||
|
|
|
||
|
|
<name> is an optional zpool name. If specified, will only output info for this zpool.
|
||
|
|
<item> is one of size, alloc, frag, cap, dedup, health and if specified, will only output the corresponding value
|
||
|
|
If --what is specified then --zpool is mandatory.
|
||
|
|
The default (with no option) is to output all the info of all the zpool in a JSON format
|
||
|
|
_EOF
|
||
|

exit 1;
