No warning if zfs version too low (was: doesn't find datasets on Debian Buster, zfs 0.7.12-2)

Question

ioztat -Hey as suggested by the man page doesn't return anything.

ioztat -SIn rpool, also suggested by the man page, gives "dataset not found: 'rpool'" (rpool of course exists).

Is there a way to further debug this? Am I missing a dependency?

As mentioned in the README, the minimum supported version of OpenZFS on Linux is 0.8. Earlier versions don't export per-dataset statistics.

Might be nice to have a version check for the failure case to give a more useful error message.

Thanks, I indeed overlooked the minimum version :(

I'll modify the subject

Fixed in c632a03 for both FreeBSD and Linux, will be part of 2.0.2.

Thanks for your report - I should have done this sooner.
