May be that I am missing something obvious, however I have to ask which
would be the purpose to balance a two disks RAID1 system.
The balance command should move the data
written lost, instead of require the user
intervention to not lost anything.
To address your requirement, we need a super sync command which
ensure that the data are in the filesystem and not only
in the log (as sync should ensure).

Could this be related to the inode overflow in 32 bit system (see
inode_cache options) ? If so running a 64bit ls -i should work
Good point. Russell might just
by the tree chunks.
The balance is related to the movement of the chunk between the disks. But the
data is unchanged.
Anyway I fully agree with you when you say:
Snapshots are cheap but they aren't free.

that is a LVM snapshot by default
should be not scanned by btrfs dev scan
- btrfs dev scan, during the partition discovery should skip the
lvm-snapshot.

grub-mkconfig quite useful for a standard user.
For more advance uses cases editing by hand grub.cfg may be possible.

so, the subvol=debian option is passed to mount. When
grub-mkconfig generates the grub menu entries, does so.
This I also have in my grub-config, and it works
of the example above, in case you want to mount a
single-disk, BTRFS seems me to work properly. You have to pay
attention only to not mount the two filesystem at the same time.
