Failed zpool after power removed from disk

[Mike Hammett]

I run NexentaStor and had some problems. If I told you everything that has happened, I'd be typing for an hour. The short of it...  when pulling a dead drive to RMA, I bumped the power on another, losing the array. I have spent a couple days trying to bring it back, but no luck thus far. Suspecting controller issues, I moved all of the disks to another controller. I have tried different things I've found on Google as well as help from the NexentaStor forum, HardOCP forum and #openIndiana on FreeNode.

I've put a summary of what's going on here: http://pastebin.com/bFDPCXt0  Does it appear to be on the right track to getting my data back, even if there is some corruption? Any recommendations?

So in short you have been trying to reimport your pool for a few hours now, and it's still "running" (in state sleeping).

And it's not zfs-fuse specific, rather zfs specific.

Well nothing much to say here, I know some people on the sun forum have been helpful in the past to recover some data from some zfs pools, but it's been a long time since I heard from them, but if somebody can help it's probably them here.

It's the kind of "nightmare scenario", I guess the controller has probably gone mad for a while, just long enough to make the whole pool unusable. Rather frustrating, considering the number of drives... sorry I can't help more here.

Actually, a few days, but only now did I have a process down where it would go any amount of time without failing in some way.

Right, just ZFS in general. Just trying to find those pockets of people that know anything about ZFS.

Thanks.
