Anyway, assuming it works, can we get this patch > merged into the main branch? FWIW I had tons of segfaults with mhddfs in the past (usually when browsing the mounted FS with Thunar file manager), then I've not used it for a period of time, then went back to using it recently, and have zero segfaults whatsoever now. I don't know what could be the change helping with this, in any case my versions are: Kernel 4.9.41 (Self-compiled) fuse 2.9.3-15+deb8u2 libc6:amd64 2.24-11+deb9u1 mhddfs 0.1.39+nmu1 One thing to check (some hunch), is any of your joined paths actually a symlink itself? -- With respect, Roman
