https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243925 Conrad Meyer <cem@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|bugs@FreeBSD.org |fs@FreeBSD.org CC| |asomers@FreeBSD.org Version|12.1-RELEASE |CURRENT --- Comment #1 from Conrad Meyer <cem@freebsd.org> --- Can you share a specific ordering of IPCs, including exact open flags used = and FUSE procedures seen on the server side? For cached IO (bio) without O_DIRECT, we probably attempt to read the last page/sector of a file we are appending to. Any local filesystem would do something similar (read a block from the backing volume when a write-only append handle is open for an uncached, cacheable file), if the file is not a perfect multiple of the page size. I think we mostly try to open separate read handles for this, but it's we missed a case. Any specific details you can share would be helpful.
