Since your metadata is already full, you may need to delete enough
data
to free up enough metadata space.

The candidates includes small files (mostly inlined files), and large
files with checksums.

On that fs, there are rather many large files (800MB - 1.5 GB).

Is there anyway to get (much?) more space reserved for metadata in the
future respectively on the other existing filesystems that haven't
deadlocked themselves yet?!

In fact, this is not really a deadlock, only balance is blocked by such
problem.

For other regular operations, you either got ENOSPC just like all other
fses which runs out of space, or do it without problem.

Furthermore, balance in this case is not really the preferred way to
free up space, really freeing up data is the correct way to go.
