I'm testing raid6, and recently added two drives. I haven't been able to properly resume a balance operation: the number of total chunks is always too low. It seems that the balance starts and pauses properly, but always resumes with ~7 chunks. Here's an example: vendikar tim # uname -r 3.10.0-031000rc4-generic vendikar tim # btrfs fi sho Label: 'bank' uuid: 682bd1f5-1bd3-479b-8882-867dfe32375f Total devices 7 FS bytes used 4.70TB devid 4 size 1.82TB used 1.44TB path /dev/dm-9 devid 1 size 2.73TB used 1.44TB path /dev/dm-8 devid 5 size 2.73TB used 1.44TB path /dev/dm-7 devid 6 size 931.51GB used 207.00GB path /dev/dm-6 devid 2 size 2.73TB used 1.44TB path /dev/dm-5 devid 3 size 2.73TB used 1.44TB path /dev/dm-4 devid 7 size 931.51GB used 207.00GB path /dev/dm-3 Btrfs v0.20-rc1-324-g650e656 vendikar tim # btrfs fi df bank/ Data, RAID6: total=4.71TB, used=4.69TB System, RAID1: total=32.00MB, used=376.00KB System: total=4.00MB, used=0.00 Metadata, RAID1: total=8.00GB, used=6.54GB vendikar tim # btrfs balance start bank/ vendikar tim # btrfs balance status bank/ Balance on 'bank/' is running 3 out of about 1479 chunks balanced (4 considered), 100% left vendikar tim # btrfs balance pause bank/ vendikar tim # btrfs balance status bank/ Balance on 'bank/' is paused 4 out of about 1479 chunks balanced (4 considered), 100% left vendikar tim # btrfs balance resume bank vendikar tim # btrfs balance status bank/ Balance on 'bank/' is running 1 out of about 4 chunks balanced (5 considered), 75% left All the best, Tim
