Hi Stefan,
looks like bluefs allocator is unable to provide additional space for
bluefs log. The root cause might be lack of free space and/or high space
fragmentation.
Prior log lines and disk configuration (e.g. ceph-bluestore-tool
bluefs-bdev-sizes) might be helpful for further analysis.
Thanks,
Igor
