Hello!, i think i made a mistake
i had two 3tb drivre on a raid 1 setup, i bought two aditional 3tb
drives to make my raid 10 array
i used this commands
btrfs -f device add /dev/sdc /mnt/nas/ (i used -f because i
formatted my new drives using gpt)
btrfs -f device add /dev/sdf /mnt/nas/
finally:
btrfs balance start -dconvert=raid10 -mconvert=raid10 /mnt/nas/
after a couple of hours i ran:
btrfs filesystem df /mnt/nas/
Data, RAID1: total=963.00GiB, used=962.69GiB
System, RAID1: total=32.00MiB, used=176.00KiB
Metadata, RAID1: total=6.00GiB, used=4.59GiB
GlobalReserve, single: total=512.00MiB, used=0.00B
should that not read raid 10 ?
output for btrfs fi usage /mnt/nas
Overall:
Device size: 10.92TiB
Device allocated: 1.89TiB
Device unallocated: 9.02TiB
Device missing: 0.00B
Used: 1.89TiB
Free (estimated): 4.51TiB (min: 4.51TiB)
Data ratio: 2.00
Metadata ratio: 2.00
Global reserve: 512.00MiB (used: 0.00B)
Data,RAID1: Size:963.00GiB, Used:962.69GiB
/dev/sdc 481.00GiB
/dev/sdd1 482.00GiB
/dev/sde1 482.00GiB
/dev/sdf 481.00GiB
Metadata,RAID1: Size:6.00GiB, Used:4.59GiB
/dev/sdc 4.00GiB
/dev/sdd1 2.00GiB
/dev/sde1 2.00GiB
/dev/sdf 4.00GiB
System,RAID1: Size:32.00MiB, Used:176.00KiB
/dev/sdd1 32.00MiB
/dev/sde1 32.00MiB
Unallocated:
/dev/sdc 2.25TiB
/dev/sdd1 2.26TiB
/dev/sde1 2.26TiB
/dev/sdf 2.25TiB
I think i made a mess here... why is system only on two drives? why
is it not showing raid 10?
If i actually failed how do i acheive this? i want all four drives in
a raid 10 setup.
Thanks in advance

btrfs has a small bug at the moment where balance can't convert raid
levels (it just does nothing), it is meant to be fixed with the next
kernel release.

I can confirm that convert works now with 4.1 kernel and btrfs-progs
