Hi, Just installed 3.9.0-rc2 and the latest btrfs-progs. filesystem is a 4 disk raid1 array. first, i did the following: `btrfs val start -dconvert=raid5,usage=1` to convert the mostly empty chunks. This resulted in a lot of allocated space (10's of gigs), with only a few 100 meg used. i did `btrfs val start -dusage=75` to clean things up. then i ran `btrfs bal start -dconvert=raid5,soft`. I noticed how the difference between total and used for raid5 kept growing. My guess is that its taking 1 raid1 chunk (2x1 gig disk space, 1 gig data), and moving it to 1 raid5 chunk (4gig disk space, 3gig data), leaving all chunks 33% used. This is what 3 calls of `btrfs file df /` looks like a few minutes after each other, with the balance still running: Data, RAID1: total=807.00GB, used=805.70GB Data, RAID5: total=543.00GB, used=192.81GB System, RAID1: total=32.00MB, used=192.00KB Metadata, RAID1: total=6.00GB, used=3.54GB -- Data, RAID1: total=800.00GB, used=798.70GB Data, RAID5: total=564.00GB, used=199.30GB System, RAID1: total=32.00MB, used=192.00KB Metadata, RAID1: total=6.00GB, used=3.53GB -- Data, RAID1: total=795.00GB, used=793.70GB Data, RAID5: total=579.00GB, used=204.81GB System, RAID1: total=32.00MB, used=192.00KB Metadata, RAID1: total=6.00GB, used=3.54GB Remco-- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
