setting up hard disk for zfs raid
I am trying to get my centos 6 to use two 1TB hard disks with zfs file system for a simple raid or mirror(?).I did have this working but one of the disks went bad and I had to replace it. I got things all screwed up trying to restore the new disk to work after replacing it. I am not very experienced with linux and need help getting things back working again. I know that this is not enough detail but am just trying to find where to start.
