Replace failed disk with smaller disk?

[lpittman]

I've done some searching and can't seem to find an answer. I read that you "should" replace a failed disk with one the same size or one bigger and I can understand why, but if you have a small amount of data is it even possible to replace a disk with a smaller one?

I ask for this reason - I bought a 3tb drive from a local store, but I was given a few 2tb drives to use... so I would like to remove the 3tb from my 6 disk raidz2 array, return it to the store and replace it with a 2tb one.

Possible?

Thanks
Luke

Nope. Not possible. You'll have to destroy the zpool and recreate it with the 2TB drives.

Ack! Never came back to thank you for your response. Got all up and running, thanks for the help.
