I started "btrfs device delete missing" command, which is running since friday, and it still seems far from finished. It seems to be doing something very strange: used space on the largest drive is going down, while smaller drives are filling up to the brim. I'm afraid it will soon run out of space and I don't know what to do. The current situation is: Label: none uuid: cff1e711-97fe-4c1c-b8a3-6184010b5027 Total devices 4 FS bytes used 376.66GB devid 4 size 172.81GB used 167.00GB path /dev/dm-16 devid 3 size 232.88GB used 227.00GB path /dev/dm-4 devid 2 size 452.26GB used 327.01GB path /dev/dm-0 *** Some devices missing According to btrfs FAQ and http://carfax.org.uk/btrfs-usage, there should be around 404GB of usable space in this configuration. Assuming even distribution, used space on each device should be accordingly: 160, 216, and 405. The current situation is FAR from that. I'd be grateful for tips what do to and how to get out of this situation. Regards
