Hello all, While it is deemed uncool to reply to one's own posts, there's often no other choice ;) Here is some more detail on that failure: this problem was located to be on the rpool, and any attempts to import it (including rollback or readonly modes) lead to immediate freeze of the system

To follow on the subject of VDEV caching, even if only of metadata, in oi_148a, I have found the disabling entry in /etc/system of the LiveUSB: set zfs:zfs_vdev_cache_size=0 Now that I have the cache turned on and my scrub continues, cache efficiency so far happens to be 75%. Not bad for a
