laff. these storage spaces do not really "belong to us" . Make sense to always keep 2-3 copies ELSEWHERE, so now this issue is just funny and inconvenient
thanks for your post and followup. I'm glad your situation was resolved positively and I can see REFS may not be reliable. I am a tentative user of 7disk-REFS with 1-mirror-copy, nothing mission-critical but I appreciate hearing the good and bad. All my backups are manual about once a week...
