OpenZFS on OS X

Hi,

I crashed my system by trying to symlink the iCloud folder in ~/Library/Mobile\ Documents to another location ... shouldn't be done, now my Mac crashes after a few seconds, even when there is no user logged in (it runs Sierra).

However, it is fine in "safe mode" - some apple iCloud Account daemon is causing the crash.

But I am not able to import the pools. Diskutil shows my drives, but
zpool import
returns
no pools available to import
same with giving a device name, the pool number, the pool name, ...
The only command which returns meaningful data is
zpool import -d /dev

Code: Select all

   pool: secure_bup

  state: ONLINE
 status: Some supported features are not enabled on the pool.
 action: The pool can be imported using its name or numeric identifier, though

I forgot which kext needs to be loaded ... maybe I need to do that manually.
Do you have any hints?

Loading zfs.kext
/sbin/kextload /Library/Extensions/zfs.kext
didn't help.

I would try using an app called LaunchControl (there's another one called Lingon) and disable anything with "cloud" in its name — I've done it as a regular trick as I don't use iCoud, wifi, bluetooth...
The only thing is I'm not absolutely sure you can do it in safe mode, but you don't risk anything trying it.
You could also try cleaning all caches manually...
Of course, if you boot from another drive OS you might have other solutions.

You have to load both kexts, so its usually

kextload spl.kext zfs.kext

using full path to both kexts of course.
