Is this the best way to install Jellyfin?

So, I've been trying to figure out how to install jellyfin with the best options here so i made my choice, and it's finally installed but i have some issue with refreshing the library,

Ok, I have a ProxMox server (Host) with 1T HDD installed, and i created an ubuntu server vm (Not Container) and installed jellyfin on that vm.

I attached my 1T hdd as a virtual hdd from host server to jellyfin vm using this code

/sbin/qm set 500 -virtio2 /dev/disk/by-id/UUID

And made it auto mount using fstab, and it's working great

However, if i made any changes to the original dir on host, it doesn't reflect on jellyfin until reboot

i.e, if i added new movie say it's Batman Begins to the host original dir, it doesn't show up in the mount point in jellyfin vm when i use ls -l until i reboot the vm.

This is a very painful process which i don't think that it suppose to be that way when i add every new file or even rename a folder i should reboot the whole vm

I tried using mount -a to remount the vda but it's not working

I tried using "sync"option in the fstab but it 's not working also

What could be wrong? and how do i fix this issue?
