Well, everything was simple: 1) 12.1, disk died, I issued "attach" instead of "replace" 2) it attached, but started resilvering in cycles, finding more and more errors (which is understandable, since both disk started to die aproximately at the same time - one was eletrically dead, another was SMART-dying) 3) at some time on 12.2 I've even had this (guess with different guids, didn't figure out to look this up), but I swear, gpt/zfsroot0 was twice in the list: both as ONLINE and UNAVAIL: config: NAME STATE READ WRITE CKSUM zfsroot DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 gpt/zfsroot1 ONLINE 0 0 0 gpt/zfsroot0 UNAVAIL 0 0 0 cannot open gpt/zfsroot0 ONLINE 0 0 0 (resilvering) 4) then I upgraded to 13.x to see if it wilkl resolve the situation. It actually did, kind of - gpt/zfsroot changed to DISK-31P58VAASp3. So, I guess you cannot detach/remove anything if these things are present: - something is resilvering - pool isn't "cleared" with zpool clear. Eugene.
