Hi,
I created a new zfs datapool on my external hard drive and it went completely fine. After I copied some files on it, I properly unmounted the file system, however, the next time I connected the hard disk, Finder did not automatically mount the zfs volume. Even zpool list claims, that there are no pools available, although the drive itself is detected by the system.
Lastly, I tried to mount the zfs volume on a different linux machine, but I get the exact same error.
Is there any way to repair the volume?
