I have had my server running for nearly a year. I am about to add a new drive and want to straighten some things out and learn more. Fix common problems have had these 3 errors since i installed it.

Invalid folder appdata contained within /mnt

Invalid folder cache contained within /mnt

Invalid folder Cache_nvme contained within /mnt

 

Obviously I have something messed up. When switching things to hardlinks would be my guess. I am very novice and probably followed a youtube video without fully understanding what I was doing. Here are the diagnostics I think are relevant. I have searched and cant figure this one out.

You must not create any folders at the top level of /mnt, that is for the OS to do.

This is probably the result of specifying the path /mnt/appdata as a host path in one or more of your containers. The correct path would be /mnt/user/appdata

If you actually had a pool named cache, then /mnt/cache would be a valid path, but since you don't, it's not. Possibly another container host path wrong.

You do have a pool named cache_nvme, so /mnt/cache_nvme would be valid. But linux is case-sensitive, so /mnt/Cache_nvme is different and not valid. Possibly another container host path.

 

You seem to have a lot of non-existent user shares in the diagnostics, which makes me wonder if you don't have other incorrect paths specified causing files to be saved at the top level of /mnt/user or some disk or pool where they wouldn't actually be part of any user share. User shares are subfolders of /mnt/user, files directly in /mnt/user and not in a subfolder are not part of user shares.

 

What do you get from command line with this?

ls -lah /mnt/user

So I should start going through every docker container and if I see /mnt/appdata I should change it to /mnt/user/appdata?

Did you intentionally create these (ab_20250129_060001 for example) as user shares?

No I did not. I believe those started appearing when I setup an appdata backup app or plugin.

So for this the metadata path is just wrong?

You must have told it to write to /mnt/user (or /mnt/disk# or /mnt/poolname). Any folder at the top level of array or pools is automatically a user share named for the folder.

 

You want to specify an actual user share, which would be /mnt/user/sharename

 

Typically, when you need to specify a path, the UI will let you browse and choose from valid paths.

yes, wrong. That will create

I assume you want it as a subfolder of that path you mapped to /config

I just took a look at that container, and that is what its template specifies, so you must have changed it to that invalid path.

Thank you trurl. I have all my errors fixed at the moment. You really helped. I am going to keep learning and adding more to my server!
