I have also an Unraid server with my media, documents, photos, etc which I will have NFS mounts to proxmox for Plex using 10gbe (using mikrotik switch and DAC cables).
What is the best way to set the storage for my drives? Is there any benefit to use L2ARC/ZIL?
On Unraid I currently have some services that run (sonarr, radarr, nzbget), should I move these over to proxmox in an ubuntu LXC container (all of them in 1 LXC container)?
How do I mount the media directory from Unraid into proxmox LXC container? Do I use fstab or bind mounts?
How do I setup backups for proxmox?
Would I install Crashplan on Unraid to backup my data or proxmox? And which OS would I use to run the software?
WIll try to answer your questions, but I'm no expert, so double check !
So many way to set this up... You could use the 2 Kingston SSD for the Proxmox OS + VM OS storage , with RAID 1. Use one Intel SSD for ZIL, and the other for L2ARC. But this would mean you have actual benefit of ZIL and L2ARC, which I don't know since I don't know what you are planning to run on your Proxmox... If this is pure homelab with only a Plex and some consumer grade stuff running I understood ZIL and L2ARC are not this useful. So I would go for RAID 1 with the slowest SSD to install Proxmox, RAID 1 with the fastest SSD for VM OS storage, and RAIDZ2 for the HDD. If you need the 9To, you may consider RAIDZ1 but it's kind of outdated and risky.
I would do so yes; This way you would have your hypervisor doing all the hypervisor stuff, and unraid fully dedicated to the storage (but it makes me wonder why you do have 12TB of storage in Proxmox then). I would do one LXC container per service. Or if you need reduced footprint, one VM with Docker container.
Never done this but I would say NFS mount no ?
Depends what you want to backup. The OS itself, the VM OS, the data ? If you are running ZFS for all the file system you'll use, you can setup a cronjob for taking snapshot and zfs send | zfs receive to another ZFS filesystem. That's how I configured mine, but I don't know if it's best practice. I'm working with 3 SSD for Proxmox OS, 2 are in RAIDZ1, the 3rd one is independent but running ZFS. I snapshot the RAIDZ1 and send it to the independent 3rd one... Same for the VM-OS. But you could simply send it to your unraid, if it's a different physical server it's even better.
