OpenZFS on OS X

I don't know where to report bugs, so I'll do it here.

$ zpool import -o readonly=on tank
$ zpool scrub tank

=> command just hangs forever. Should either work or return something like "Scrubbing a read-only pool is not supported".

zfs-macOS-2.2.3-1
zfs-kmod-2.2.2-1

What version of the operating system are you running, and on which hardware platform (Apple Silicon/Intel)?

Those kext versions don’t match, so something has gone wrong there - they should probably both be 2.2.3.

You might want to uninstall/reinstall and check again.
