* bluestore: common/options.cc: disable bluefs_preextend_wal_files <-- from 15.2.3 changelogs. There was a bug which lead to issues on OSD

Given that preextended WAL files was mentioned as a speed increasing feature in nautilus 14.2.3 release notes, are nautilus clusters in danger or just Octopus?

restart, and I believe this was the attempt at mitigation until a proper bugfix could be put into place. I suspect this might be the cause of the symptoms you're seeing.
