It appeared to me that increasing "bluefs_min_log_runway" config option to a really high value is one way to prevent this problem from occuring on OSDs where the fix (https://github.com/ceph/ceph/pull/25132/commits) isn't available, since the write operations would get prevented early (in case of low-space) and compaction can happen without trampling on the last available free-space.
Can someone comment on whether this looks like a good workaround to prevent the condition?
