> I should have been more specific about the concatenation issue (see the note at the top of the page you linked). While it looks like you are adding a drive to RAID5, what you are doing in redundancy terms is no different from adding a single drive vdev to a ZFS pool. You get more space, but that drive becomes a single point of failure with SVM and ZFS.
According to the docs, the drives data is included in the parity calculations, but the parity data is only stored on the original drives, which shouldn't be a problem since raid-5 uses the same amount of parity data no matter how many drives in the array. Unless the docs are wrong, in which case I would defiantly want to know, and it would indeed be useless.
