I have RAID 10 using 4 times 500GB drives (1TB of storage).
Is it possible to create another RAID 10 with 4 times 250GB drives
(500GB of storage) and then combine those two RAIDs to one file
system so that I would be able to get 1.5TB?
If I create one RAID 10 with all 8 drives I would only be able to
use 8 times 250GB /2 = 1TB, right?
No, just add the new drives to the existing btrfs pool, and run a
balance, and you should get a btrfs filesystem with 1.5TB of
mirrored/striped storage.
