I just checked, and it does not send ctime to the fuse daemon: * when changing atime * when changing ctime * when truncating, at least when writeback cache is disabled. Does moosefs use the writeback cache? And which FUSE protocol level does it use? --=20 You are receiving this mail because: You are the assignee for the bug.=
