There a various things yet to try, but I have no personal experience = with them: - "force" read-only import - import referencing a past transaction group, i.e. a previous version = of the entire pool How to find these transaction groups - no idea, sorry. >>> The host is running the lates Xigmanas BETA, which is effectively >>> FreeBSD 14.1-p2, just for the record. This topic including sometimes successful recovery frequently pops up on = the TrueNAS forum. Did you ask in the Xigmanas community? Weren't they able to help? I know there are regulars on the TrueNAS forum who know what to do. = Maybe head over there?
