Despite this, the pool and its filesystems mount in the Finder and the pool is working fine otherwise.
The pool shows as follows:
Oddly, according to the OS, the disk is listed thusly:
So despite the disk mounting properly, at least some part of the OS is confusing ZFS for "Microsoft Basic Data".
The OS is 10.13.2.
Despite this, the pool and its filesystems mount in the Finder and the pool is working fine otherwise.
The pool shows as follows:
- Code: Select all
pool: ext-bkup
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.
scan: none requested
