[ceph-users] bluefs_buffered_io

Hi list, I see a few changes in the (minor) version changelogs in the default for bluefs_buffered_io setting. Sometimes it is set to true in our version (14.2.11) it is set to false Can someone shed a light on this setting? I fail to find any documentation on it. ceph config help is not entirely clear to me as well - What does it do exactly when true - If false does that mean that the linux buffer cache is always skipped? And caching happens in the osd proces only? - if enabled should we lower the osd_memory_target to leave more space for the linux buffer cache? What would be the percentage of memory that we then assign to osd_memory_targets Marcel
