Thanks for your hints. The balance is running now for about 11h: The status is a bit surprising to me: 0 out of about 2619 chunks balanced (4165 considered), 100% left btrfs fi usage is also surprising: Overall: Device size: 8.19TiB Device allocated: 2.56TiB Device unallocated: 5.62TiB Device missing: 0.00B Used: 2.56TiB Free (estimated): 11.65TiB (min: 2.81TiB) Data ratio: 0.48 Metadata ratio: 1.33 Global reserve: 512.00MiB (used: 0.00B) Data,single: Size:2.55TiB, Used:2.55TiB /dev/sdc 1.60TiB /dev/sde 975.44GiB Data,RAID5: Size:2.73TiB, Used:2.72TiB /dev/sdc 1.12TiB /dev/sdd 2.73TiB /dev/sde 1.61TiB Metadata,RAID1: Size:6.00GiB, Used:5.33GiB /dev/sdc 5.00GiB /dev/sdd 1.00GiB /dev/sde 6.00GiB Metadata,RAID5: Size:3.00GiB, Used:2.99GiB /dev/sdc 2.00GiB /dev/sdd 1.00GiB /dev/sde 3.00GiB System,RAID5: Size:32.00MiB, Used:736.00KiB /dev/sdd 32.00MiB /dev/sde 32.00MiB Unallocated: /dev/sdc 1.02MiB /dev/sdd 1.02MiB /dev/sde 164.59GiB I hope, that is because Raid5 is not implemented yet?
