Proxmoxa shared raid5 plexmediaserver between omv

[uzzo]

hello I have raid5 software made on debian. i wanted to use proxmox to have 2 vm plexmediaserver on it and smb i was thinking about openmediavault. how to make the data from raid 5 visible on plex and omv. raid5 formatting is not part of the game. how to properly do it in proxmox

You can't bind-mount folder from the host into a VM. That only works with LXCs. The usual way to bring folders from the host into a VMs would be to:
1.) turn your Proxmox VE Host itself into a NAS by installing a SMB/NFS server bare metal and setting it up using the CLI
2.) Create a LXC to work as your NAS, bind-mount the folders from the Host into the LXC, install and setup NFS/SMB server inside your LXC

Or you don't create the raid on the host at all and do that inside the VM. But then your host won't be able to also use the disks (unless you mount a NFS/SMB share provided by your VM):
3.) don't use the raid5 on the host. Pseudo-passthrough the individual disks using disk-passthrough into your OMV VM and then create the raid inside that VM. Your host won't be able to use the disks, unless you also mount a SMB/NFS share there.
4.) don't use raid5 on the host and passthrough the whole disk controller into the VM with ALL DISKS attached to it using PCI passthrough. This is the only way how a VM could directly and physically access the real physical disks. Then create the raid inside the VM.

it will stay with the physical system. it seems to me that there will be a decrease in machine performance if there is, for example, smb data shared to the plex server instead of physical access to files.
