Restoration of ZFS Snapshot

[edgeofthex]

Hello,

A year ago or so, I used this script to create a 3 disk raidz1 array, and install debian. I'd like to add a disk to this array.

Is it possible to use sgdisk to zap the disks in the array, then run this install script again, killing it after the array creation with the added disk, then restoring the backup/snapshots onto the array?

If not, I'd appreciate it very much if you could suggest at least generally how I might create that array manually. I've followed the instructions on the ZFS-On-Linux web site to install Debian before, and understood pretty much what I was doing. I don't fully understand how your script does what it does.

Thanks!
