Odd that this should suddenly appear now. > And what zpool and zfs version are you running?

Right now it's: FreeBSD lucid-nonsense.infracaninophile.co.uk 8.2-STABLE FreeBSD 8.2-STABLE #3 r231563: Mon Feb 13 01:37:39 GMT 2012 root@lucid-nonsense.infracaninophile.co.uk:/usr/obj/usr/src/sys/LUCID-NON= SENSE amd64 Which is stable/8 from last Sunday. I hardly think that qualifies as "old." I am planning to upgrade to stable/9 in the reasonably near future -- perhaps I'll do that sooner rather than later if it offers any potential fixes. I wasn't aware that there were many changes between stable/8 and stable/9 in respect of ZFS. > If you are using a recent STABLE pull, and have created the pool with a= n > old version of FreeBSD, have you considered destroying the pool and > recreating it with your backups, using zfs send & recv? Hmmm... no. That sounds like a thing to try when I have a day or so that I can take the machine down for. Probably right around the point that I do the upgrade to 9.x. Thinking about it, I'd probably split the mirror, rebuild one of the drives, pull the ZFSes across, boot from the rebuilt drive and then add the old drive back to the mirror.
