If `all` is enabled and you're sure it's not working then please provide straces again because the mergerfs strace provided before isn't useful since it doesn't actually perform the hack.

cat isn't the app which is access the file. mergerfs is. You'd have to give that cap to mergerfs. mergerfs doesn't handle permissions. The kernel does. So I think when...

What's surprising? Caps aren't part of the FUSE protocol. There are lots of extra kernel features that aren't. Namespaces for instance. There isn't anything in the protocol that shares the...

Ahh. I see why that would be useful for backup software. Like I mentioned... I think if you just set the cap on mergerfs it should work as expected. The...

>The version of cat WITH the capability still can't read the file even though mergerfs also now has the capability. Also, mergerfs appears to still be getting calls from the...

I can't speak to the issue with strace on UnRAID. Should talk to the vendor. As for performance you have to ensure you're comparing like for like. The kernel will...

BTW... I just tested a local + sshfs setup and it seems absolutely fine including after purging caches.

That is curious. I'll test later with rclone in the mix.

You are using an old version of mergerfs then. Those aren't fuse options. They are mergerfs ones as found in the man page and web docs. If they don't work...

They improve perf so much on following calls because it's caching the relevant info as described in the docs. That doesn't explain the initial slowness.
