Hey folks -
First: I have the pertinent data backed up onto another server, so if all is lost, that's fine. Obnoxious and awful because it'll take 24 hours to put it back. But, whatever.
I had two FreeBSD servers and I decided to try and merge them. The first server is my login/email/web/etc one: dual Xeon, lots of memory, not a whole lot of storage. The second: my NAS with 8 x 4TB drives in a ZFS version of RAID10 pool. The goal: move the first server's motherboard over to the chassis of the second, and connect the drives up. With any luck, I'd be fat, dumb, and happy, and all would work.
The challenge is that I had a pool on Server 1 called "local". The pool on the NAS is also called local, and I was a bit concerned there'd be some name collision. I tried to
As far as I can tell, the 8 drives that were originally in the NAS are all fine. They each respond to
Can I do something to the server to first get it to forget about this local entirely, and then import the bigger one? Or is there something else I need to do?
Thanks for any guidance!

zpool export local
on Server 1, hoping it would "forget" about that pool. But I guess that wasn't enough. Shows my ignorance. Upon booting after the swap and merge, the "new" server is unhappy:
Code:
arkham# zpool status local
pool: local
state: UNAVAIL
status: One or more devices could not be opened. There are insufficient
replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.

As far as I can tell, the 8 drives that were originally in the NAS are all fine. They each respond to
camcontrol
commands, they just have different device numbers than before.Can I do something to the server to first get it to forget about this local entirely, and then import the bigger one? Or is there something else I need to do?
Thanks for any guidance!
