Using mergerfs over NFS doesn't seem to work

[thomaswilliamsastro]

Hi,

I'm currently trying to export my mergerfs pool over NFS to my Steam Deck but am having issues getting files to even show. For reference, I'm using a Synology and their NFS permissions generally work (I can see files, at least), but any mergerfs pools show up as empty. I'm following the recommended settings, as far as I can tell, so in my mount:

mergerfs -o rw,use_ino,allow_other,func.getattr=newest,category.action=all,category.create=mfs,cache.files=partial,dropcacheonclose=true,noforget,inodecalc=path-hash /volume1/EmulationVolume1:/volume2/EmulationVolume2:/volume4/EmulationVolume4 /volume1/merge/Emulation

so I'm definitely using noforget and the inodecalc needed, and then I'm adding to /etc/exports

/volume1/merge/Emulation 192.168.0.245(rw,no_root_squash,anonuid=1024,anongid=100,fsid=UUID)

so this has the no_root_squash and fsid requirements. This just doesn't seem to be working, and I'm confused as to why. Must say I'm not an expert in this at all, so any help would be most appreciated!

What version of mergerfs? Make sure it's the latest and maybe try changing cache.files=off.

I had updated to the latest version, the way I got it to work was to make sure the shared folder (/volume1/merge) was shared via the Synology GUI, then not use no_root_squash for the .../Emulation share. Seems not being able to see anything was a permissions issue, oddly. This seems to be working fine now, though I'll keep an eye out for any weirdness
