From these basic types, "stacked" or "nested" RAID volumes can be created.
Stacked RAID sets that make use of mirrored RAID sets are fault-tolerant.
For concatenated RAID sets with a resizable filesystem, delete will attempt to shrink the filesystem to fit on the first member partition and convert that to a non-RAID volume. New disks are added live, the RAID volume does not need to be unmounted.
This allows the software to reformat the entire disk using the most current partition layouts. Using the UUID is preferred because disk device names may change over time when disks are added, disks are removed or when the system is rebooted.

When ownership is enabled, the Owner and Group ID settings that exist on the disk are taken into account for determining access, and exact settings are written to the disk as FSOs are created.
