https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251363 --- Comment #7 from Gunther Schadow <raj@gusw.net> --- Erratum: I said "I can evict from the cache by writing to the unionfs" -- I meant by removing files from that /cache file system. I wasn't clear that in order to mount a unionfs, you must already have the upper layer file system mounted somewhere. And then you can access just the upper layer, where we c= an clear the cache. So I do not need that UNIONFS_WHITE_NEVER option at all. What might be cool was some kind of hook to register if the unionfs_copyfile errors with no space left on device, we could call that evictor hook, which then would delete from the upper layer by oldest atime. --=20 You are receiving this mail because: You are the assignee for the bug.=
