Yes, you were right! Adding another drive to the array made it
continue without errors. Is this already reported as a bug?
Thanks for the help,

Hi list,
I am using kernel 3.9.0, btrfs-progs 0.20-rc1-253-g7854c8b.
I have a three disk array of level single:
# btrfs fi sh
Label: none uuid: 2e905f8f-e525-4114-afa6-cce48f77b629
Total devices 3 FS bytes used 3.80TB
devid1 size 2.73TB used 2.25TB path /dev/sdd
devid2 size 2.73TB used 1.55TB path /dev/sdc
devid3 size 2.73TB used 0.00 path /dev/sdb
Btrfs v0.20-rc1-253-g7854c8b
# btrfs fi df /mnt/data
Data: total=3.79TB, used=3.79TB
System: total=4.00MB, used=420.00KB
Metadata: total=6.01GB, used=4.87GB
When running
# btrfs balance start -dconvert=raid5 -mconvert=raid5 /mnt/data
I get
ERROR: error during balancing '/mnt/data' - Invalid argument
There may be more info in syslog - try dmesg | tail
dmesg | tail says:
btrfs: unable to start balance with target data profile 128
Isn't it possible to convert raid level to raid5?
Yes, it should be possible. It looks like the kernel's got a
problem with it, which is odd because 3.9 should know about RAID-5.
Wasn't there some issues that the kernel or tools wanted 4 disks when
converting to raid5?

Hugo.

It's just that we haven't worked out most of them yet.
