But I could be wrong.
You're right that -T works without F[X] flag, but -X needs -F. Unfortunately not specifying a distinct txg leads to panic. Specifying one leads to "device is missing". Which is true, but only redundant data... It's abosultely sure that this pool never had any log or cache or other device than the two mirror vdevs. zdb -l confirms that. Have tried several different txg IDs, but the latest 5 or so lead to the panic and some other random picked all claim missing devices... Doh, if I only knew about -T some days ago, when I had all 4 devices available. I haven't expected problems due to missing redundant mirrors. Can anybody imagine why degraded import doesn't work in my case and how to work arround? Will try to provide the sparse zdb dumps in addition, maybe that changes anything. But I'm sure these don't have much data., dump time was within 3 seconds at most.
