NFS Share Problem

[noz1380]

When I try to access the NFS share on the RetroNAS, I can mount the first level IE storage, but I want to mount the next folder level up. I hope this makes sense??

IE "my_Ip_Addy:/storage" mounts fine but "my_Ip_Addy:/storage/rgbpi-OS4" wont mount.

Can anyone assist please?

to the best of my knowledge,

nfs mounts the export, you cannot mount folders under export unless you use something like mount --bind after mounting the export somewhere.

so to achieve what you are after you might mount storage somewhere other than the final mount dest then either symlink or mount --bind the rgbpi-OS4 folder to the final destination

alternatively you could provide a second export that targets the rgpbi-OS4 directory on the nfs server then mount that like any other

Ok I think I follow. Not used to NFS.

I'll try the last option when home this evening, see how I fair.

Thank you.

I think the problem is RGB-PI side....

[sairuk]

if you can get a terminal on the rgbpi side you should be able to do a couple of things to try and troubleshoot this

check dmesg output for errors
# dmesg

check the mount is visible for the rgbpi
# showmount -e <retornas ip address>

mount manually with verbosity and check for errors
# mount -vvvv -t nfs <retronas ip address>:/storage/rgbpi-OS4 <mount point>

I have used fstab in the past, but I'm unsure what this is asking....

[sairuk]

command still needed a mount point, i edited my resp above to make it clearer sorry

So, the work around, make a directory in the root, symlink to the other directory, then mount the root directory and add to exports. All connects up now......RGB-PI OS should support sub-folders, but its at Alpha stage, and its not working correctly.

Only issue now is the the RGB-PI OS doent seem to like symlinks, and stops where I have nes symlink to /storage/roms/nintendo/famicom

I'll keep digging......
