Shared storage using HW RAID-backed virtual disk

[louistully]

I've recently migrated from ESXi to Proxmox and am looking to configure some shared storage for the guest VMs.

I have 8 x 1.8 TB disks in a RAID6 array on a PERC H730 mini controller.

What's the simplest way to configure this 10 TB virtual disk so that I can map it into the guests? The guests include media (Plex, Jellyfin, Immich) and file sync (Nexcloud) servers. I would prefer not having to deploy a VM to manage the disk, if possible.

Thanks, all.

I'm guessing you run a single node setup then, with the RAID6 on it ?
Just make the RAID6 a LVM pv, to host a lvmthin volume for your VMs if so, I guess you could even do it fully in the UI

Yes you can do it all in the UI using this methodology. I prefer having a separate storage server, but that is just me. How are you going to back up the data?

Yes, it's a single node setup on a Dell R630. OS and VMs are on a separate set of disks that are backed up. These are the 8 SAS drives that I want to use purely for file storage.

So, easiest is indeed set up a LVM PV/VG on that raid6 device (it should appear in the Disks section of the Host settings), and create a Thin LV on top of it, and enjoy thin provisioning, snapshots, and all.

You can also set it up as ZFS if you plan on using replication at some point, but if you plan on staying on a single node.. Thin LVM is the way to go!
