ZFS to the rescue!

So this weekend I had to do a system reinstall. Thankfully I had all my data on a pair of sata drives in a ZFS raidz. But I had to totally reinstall my system with a new motherboard, new SATA controller, etc.

I had to redo a bunch of things manually... NIS, passed, DHCP, etc.

The one thing that I didn't have to worry about: ZFS. I just plugged my SATA drives in, and did "zpool import -f data" (my dataset was called "data", which I could have figured out by just doing "zfs import" without options.)

That was it. One command only, and my raidz mirror was back in business, mounted in the right place, and even the right ZFS fileystems were NFS exported with the right options. Thank-you ZFS!

ZFS developers, I owe you a round, or three. Let me know if you want want to collect. :-)
