So I had a spare storage system that I really only used on my DMZ, to swap data to for machines I was working on that weren't allowed on my main network. Basically an ancient dell, with 4 spare drives I had laying around. I did this a few years ago, so I have forgotten exactly how I had it set up. but I *think* what I did was 3 drives in ZFS RAIDZ1, (250GB apiece) and a 4th drive that was 750GB set up as a mirror to the vdev. One of the drives is completely dead, the one I thought was the mirror. However upon booting the system I was getting "status unavailable" for everything. I decided to try and detach the zpool and reattach it, and now I am even more confused. Let me paste what I can see now and maybe someone can help me shed light on it?
Code:
[root@DMZNAS] ~# zpool status no pools available [root@DMZNAS] ~# zpool import pool: TANK id: 1936822090422793928 state: UNAVAIL status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: http://www.sun.com/msg/ZFS-8000-6X config: TANK UNAVAIL missing device raidz1-0 ONLINE ada0p2 ONLINE ada1p2 ONLINE ada2p2 ONLINE Additional devices are known to be part of this pool, though their exact configuration cannot be determined.
