Looking for an easy way to link one account to servers on multiple "machines"

Server Version#: 4.147.1

Hi. I’m wondering if there’s any way I can make it so my one server can stretch across multiple “machines”. Reason for the quotes is I’m triple booting my laptop (Windows, Ubuntu, and Debian). All three operating systems have Plex installed and give remote access to the same files on the same external hard drive. I’ve logged into my account on each OS, but any time I log in and update the library, when I look on my firestick, or any of my friend’s firesticks, an entire new server is created per each OS.

So I’m wondering if there’s a way Plex can recognize that regardless of which OS (“machine”) I log into, it can come up as the same server. Having three servers for the same files seems silly to me. Especially now considering my main server is on the Ubuntu OS and I intend on upgrading the OS with a clean install. Which means I’ll have to reinstall and re-log into Plex and then I’ll have three servers and a fourth that I won’t be able to have access too?

Sorry, I’m relatively new to Plex and this forum. I had no idea how to type this issue into the search to see if anyone else had this problem, so I’m very sorry if it’s a repeat issue. But is there any way, no matter which system/device/machine I log into, it can all be “TheHighestFive” ?

Not possible, each of your OSes are unique. Not something any real app is designed for. I would suggest a NAS or stand alone device.

Actually, this should be possible. As long as all 3 instances of pms are using the same database and same machine identifier, they should appear as the same server.

It is still impractical. Because even then all three instances won’t use the same database and settings storage. All media analysis and metadata edits would need to be performed in all three instances separately.
And no, the plex data folder cannot be shared among the three instances. Particularly not between Windows and UNIX-based OS’.
