Description Of Issue
After several reboot I can see that the external drives are not detected by Roon, but I can see them in the screen connected to the server.
Every time I reboot the server the discs are unavailable. After several reboots the drives are seen by Roon and import / add folder sequence must be started again.

Please any help?
It is recommended to reinstall Roon Server or something is wrong?
