Unable to add new Datastore

I’m having trouble adding a new external hard drive to amp on Linux.

OS Name/Version: Linux/Debian 14

Product Name/Version: AMP 2.7.2.8 - 20260520.1

Problem Description:

I cant get AMP to add the external hard drive we get error.

 Unable to add new datastore.

Unable to write to provided datastore directory. Check that the user AMP is running as has full read/write/execute access to that directory.

Actions taken to resolve so far:

We have use the commands

sudo chown -R amp:amp /path/to/datastore

sudo chmod -R 775 /path/to/datastore

sudo su - ampinstmgr fixperms

This is most likely a us thing but we need help at this point.

Is this a fixed drive that shows up in /etc/fstab?

We changed the format to ext4 and we can see it but im not 100% sure what you asking.

Ok I looked up what you were talking about and am going to try that as soon as my friend gets home me and him run a server together for friend and family and needed to ad some room for a game. If you have link to setup info that would be appreciated as we are some what new to Linux but we want to move over to it soon as windows is becoming a pain.
