That worked for about 25 minutes. Mint has been giving me trouble anyway, so I am switching back to Fedora. Not sure what the permanent solution would be, but I do not want to keep fighting with this. Thanks again.
The better solution is to manually mount the drive via /etc/fstab. I'm wondering if the drive is getting unmounted due to inactivity. That is what happened with my extra hard drives on my desktop when I allowed the OS to auto-mount them.
Jellyfin 10.10.3 (Docker)
Ubuntu 24.04 LTS
Intel i3 12100
Intel Arc A380
OS drive - SK Hynix P41 1TB
Storage
3x WD Red Pro 6TB CMR in RAIDZ1 (JF Library)
I had already added the drives to my fstab file when I installed Mint. I found several threads on the Linux Mint forum about Mint changing ownership of directories to root for "unknown reasons" according to a couple of the forum moderators, including the /home directory.
