Cyberjock's presentation on VDevs, zpools, etc. (stickied in these forums, for those who have not had the pleasure of reading it) states that within a given zpool, the failure of any VDev results in the failure of the whole zpool. I don't completely understand why this is true, but I'm starting to put the pieces together as I read more about zfs. Cyberjock also states that zpools and volumes are the same thing. Therefore, I would think that creating 2 volumes on my FreeNAS machine, each with a single VDev, would ensure that that failure of one VDev will not result in the failure of the other VDev.
However, this guide (http://www.allanjude.com/bsd/zfs-zfs.html) distinguishes volumes from zpools, stating that volumes are more akin to datasets. So which is true?
The point of this:I have a functioning RAID1 array and I would like to add new HDDs completely separate from this array. I do not want the failure of either array to affect the other.
