I can see a couple of things that are suspect here;

  create -o version=28
maczfsprototype  feature@async_destroy

If we create a pool version 28, then it should not set the feature-flags. They belong only to pool version 5000.

maczfsprototype  ashift                 0

That is clearly undesirable.

In the ZEVO support forum: Alignment at the Core Storage LVM layer, ashift above?

… I guess that if alignment is proper at the (lower) Core Storage layer, then I can accept the default ashift 0 at the (upper) ZFS pool layer. …

Without Core Storage –

ashift                 0                      default

– and:

feature@async_destroy  disabled               local
feature@empty_bpobj    disabled               local

None of those things are an obstacle to ZEVO Community Edition 1.1.1:

  • the import by ZEVO is dynamic and without force
  • feature@ values are not listed in output from zpool get all for the pool.

I experimented with setting the ashift value to 9 at time of creation by MacZFS prototype. The setting did not work around the issue.

In the ZEVO support forum:

Getting ashift property values: use zdb, not zpool

With ZEVO Community Edition 1.1.1:

• the zpool get subcommand does not work for the ashift property.

These issues, whatever they may have been, have likely been fixed for a while now.

It is worth noting that we now have even better CoreStorage support for new pools, since it will no longer attempt to partition the logical volume, which is not able to be partitioned since 10.8.5
