You were never at any risk in this scenario.

The only thing exporting a pool does is declare "I am not being mounted by someone else". The FAULTED state would be because the search paths for the devices didn't exist. Clearing /etc/zfs/zpool.cache and doing `zpool import -f` would fix it entirely (ZFS identifies the disks by UUIDs in the headers AFAIK).

Mostly true, but I've found this doesn't work if one of the drives is missing. It doesn't handle renames simultaneously with drive failure, or at least it didn't four years ago.

Using /dev/disk/by-uuid is always safe, though.
