And add it to the AVZ, this is not backwards compatible with older pools
due to an assertion in spa_sync() that verifies the number of ZAPs of
all vdevs matches the number of ZAPs in the AVZ.
Granted, the assertion only applies to #DEBUG builds - still, a feature
flag is introduced to avoid the assertion, com.klarasystems:vdev_zaps_v2
Notably, this allows to get/set properties on the root vdev:
% zpool set user:prop=value <pool> root-0
Before this commit, it was already possible to get/set properties on
top-level vdevs with the syntax <type>-<vdev_id> (e.g. mirror-0):
% zpool set user:prop=value <pool> mirror-0
This syntax also applies to the root vdev as it is is of type 'root'
with a vdev_id of 0, root-0. The keyword 'root' as an alias for
'root-0'.
The following tests have been added:
- zpool get all properties from root vdev
- zpool set a property on root vdev
- verify root vdev ZAP is created
