If we create zvols in the Control/Primary Domain with volblocksize 128K (for
performance), creating ZFS Storage Pools in the Guest fail spectacularly and
become UNAVAIL. The customer first noticed this when they tried to expand
one of their existing Guest pools by creating a new zvol in the dpool within
the Control Domain, exporting it to the guest, and running 'zpool add <pool> <new
vdev'. This caused the entire pool to go UNAVAIL immediately upon running
the zpool add command.
After the fix for Bug 15824925 - SUNBT7206382 zvol should support DKIOCGMEDIAINFOEXT, the physical blocksize of a zvol is reported as the same its volblocksize property. This caused the ashift to be calculated as 17 when we created a zpool on the zvol.
