Just FYI: With quotas disabled it took ~20h to finish the balance instead of the projected >30 days. Therefore, in my case, there was a speedup of factor ~35.


and thanks for the quick reply! (and for btrfs general!)


BTW: I'm wondering how much sense it makes to activate the underlying bcache for my raid1 fs again. I guess btrfs chooses randomly (or based predicted of disk latency?) which copy of a given extend to load? I guess that would mean the effective cache size would only be half of the actual cache-set size (+-additional overhead)? Or does btrfs try a deterministically determined copy of each extend first?
