running MacOS Big Sur 11.2.3 (20D91) with
OpenZFS 2.0 zfs-2.0.0-rc1_452_g964b2a6de7 and
zfs-kmod-zfs-2.0.0-rc1-452-g964b2a6de7
After successful installation (passed all security checks for full update and rebooted, all tools available), I cannot import my ZFS 5 pool from an external USB drive that is importing just fine under Linux (Manjaro Linux 5.11).
However, zpool import cannot find any pools (also tried with -f <poolname>).
I have to dig out the logs again but believe I've seen some notices in dmesg about a firewall blocking zfs kernel module, but that doesn't make much sense, I will supply this tomorrow.
In the meantime I would be very thankful for any hints on what I'd have to look out for with ZFS on MacOS X.
