I think this is a fairly straightforward question but my Google-Fu isn't good enough to find an answer apparently. Can you map a subdirectory of an already mapped location to somewhere different like the following?

/config  ->  /mnt/user/appdata/PlexMediaServer
/config/other  ->  /mnt/user/other

I have tried mapping the above to see if it works like I'd hoped but I've either done it wrong or it doesn't work.

I don't think it would work with a parent + a sub.

 

Why don't you just map /other instead of /config/other?

Usually simpler is better.

 

Otherwise an alternative is to create symlinks in the host which I try to avoid doing in /mnt/user because of potential issues with Unraid own shfs process.

I'd like to but I don't think I can move it. The real 'other' is Plex's cache folder for Sync jobs is filling up my relatively small cache drive.

If I were do go this route what precautions should I take to not mess up anything? Could I symlink within the docker image to /other and then map that?

What I do is to map disk and not user share just to be 100% sure there can be no wrong.

So let's say I have /mnt/user/other that is on the array and /mnt/user/appdata/PlexMediaServer on cache.

Then

cd /mnt/cache/appdata/PlexMediaServer
ln -s /mnt/disk1/other other

You get the picture. Obviously appdata is set to Cache = Only so that there won't be any mover action.

 

The map /config to /mnt/cache/appdata/PlexMediaServer

Then anything written to /config/other => /mnt/cache/appdata/PlexMediaServer/other => /mnt/disk1/other

 

It's overly cautious but I rather err on the safe side.

 

That's done the trick, thanks for the help
