had one hard drive fail in a 4x1.5 TB ZFS setup and am now stuck. status output is below. Since it's a raidz1 vdev, I am still hoping for recovering it. My issue is that since I cannot import the pool, I cannot 'zpool detach' or 'zpool destroy' the now non-existent device - only get 'pool is unavailable'. That happens even when I import with the secrect -V option (only way I don't get an error message in the first place).

I have searched every forum, but to no avail. Anybody got any ideas remaining? I am hoping that by removing the faulted disk from the configuration I will go to degraded status, but simply cannot do that.

Thanks a million, Alex

Are you sure it's just one disk that has issues? The whole pool shouldn't go into the faulted state when just one disk drops. –  Shane Madden Jan 12 '13 at 20:56
Did you replace the bad disk with another? What OS are you running? –  ewwhite Jan 12 '13 at 21:12
I cannot replace the disk because the zfs replace command does not recognize the pool as existing - even after the -V import. Exactly the same as detach. As for the other disks, I can dd from them easily, is there a way to test whether their zfs metadata is fine? I have tried this on the eon storage appliance (which is based on Solaris snv_130) and under zevo on Mac OS. Thanks! –  Alex Niemeyer Jan 13 '13 at 14:20
