Hello,
I have to build a RAID 6 with the following 3 requirements: • Use different kinds of disks with different sizes. • When a disk fails and there's enough space, the RAID should be able to reconstruct itself out of the degraded state. Meaning, if I have e. g. a RAID with 8 disks and 1 fails, I should be able to chose to transform this in a non-degraded (!) RAID with 7 disks. • Also the other way round: If I add a disk of what size ever, it should redistribute the data, so that it becomes a RAID with 9 disks. I don’t care, if I have to do it manually. I don’t care so much about speed either. Is BTrFS capable of doing that? Thanks a lot for your help!
