Hallo, Hugo,

What's the 'solution' though to Hugo's situation?
By 'solution' I mean the highest-utility way of dealing with unequal
devices problem in a two or more -up setting.

   Use mkfs.btrfs -d single, as I said in another part of this
thread.

Does "single" allow adding new (bigger) disks and removing old (smaller)  
disks?

Viele Gruesse!
Helmut
