feature request: check all zpools present, rather than selecting one about nagios_check_zfs_linux

[zlacelle]

Hmm, I'll take a look at this. Just merged in a few other things, so hopefully I can update this a bit faster than previously :)

Can you send me the output of "zpool status" on a system with multiple pools?

[2bjc466]

Sure, this is from a FreeBSD 12.1 system:

$ zpool status
  pool: data

Here is the output on a Debian Bullseye system with multiple pools.

hbarta@acorn3:~$ zpool status
  pool: bpool
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
        still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(5) for details.
