Same, it sounds like Zen 2 is the oldest in your cluster. All of your VMs should be configured to expect a Zen 2 host, and the only thing they will not have enabled is AVX512. If you know for a fact you have a specific need for AVX512 (hint: you don't, your prod hosts do not have it) then you...

On each VM, set the virtual CPU type to the closest common ancestor to all the processors in the cluster. In this example I would probably choose EPYC-Rome. If you try to migrate a running VM to a host lacking any of the enabled instruction set extensions, the VM will crash. Your Ryzen cores...

https://mirror.ip-projects.de/isoinstaller/proxmox-ve_7.3-1.iso 7.4 would probably be better for you though. if you are having crashes, we should work on that here and not through the hardware vendor.

I can't speak directly for vSAN datastores but I imagine they are still symlinked on each ESXi host in /vmfs/volumes and from there the individual VM directories are organized in the same way as a local VMFS datastore. On my standalone ESXi hosts, I would mount the VMFS datastores on my PVE...

Are your VMs critical? How does your environment behave when you are down 1 node? Have you ever tested running that way for a week or two? Have you ever tested a whole node recovery?

You can add all the disks at once, but I would only create 1 new OSD at a time. Wait for the recovery to complete before creating the next.

I would not do any kind of cluster based on what you describe. Let your engineering students handle an infrastructure of disaggregate, heterogeneous, borderline junk hosts. This kind of environment will give them the best preparation for many of the situations they will encounter in the early...

There will be a little overhead but it is not game-changing. I have 54 pfSense VMs, and 30 of them are on PVE, the rest are on Hyper-V and VMware. None of them have physical interfaces that are passed through, it's fine. I imagine OPNSense is similar to pfSense, and while you will want to use...

The design is not OK, sounds like you should wait until July when you can build with all available nodes. 7 nodes is an OK number to start. 3 host is the absolute minimum for any kind of cluster. In my opinion the minimum for prod Ceph is 5 nodes. The fault tolerance offered by a system is...

If this were me, I would want a 5 node 100 GbE PVE + Ceph cluster similar to what I described previously. This is based on my suppliers and pricing in the US, which I dont want to share on the forum, so I don't know how it would work for you in your situation, or if you are a builder or more of...

ok, 30k isn't that much. what is the logic behind having 2 non-redundant servers in 2 sites? do you need 2 sites? wouldn't you rather have a redundant setup in 1 site? what is your current actual storage usage?

Yes I was speaking more of the traditional SAN black box / delivered turnkey storage solution, and you are speaking strictly about Blockbridge which is very specific and probably the best case scenario. I swore off SAN hardware 10+ years ago, it's just been a historically poor value compared...

I know BB is a very high end SAN but we don't have a real budget or spec yet. Even in a share-nothing enclosure, the metal on the outside is shared. Got to admit, I got you there.

I would post the complete specs of your current host hardware, the current resource allocations and future requirements of all of your VMs, and your budget and expectations for this expansion and any other constraints you can think of that you haven't shared. Also what country are you in...

Setups this small are not going to allow you to transparently continue operation during failure or maintenance. You will have to supervise the failover and failback of your production services between the replicated VMs. I don't know how you can get "full" DR + HA capability of a large...

NFS and SMB\CIFS both have their strengths. Before you decide on the communication protocol, you should decide how you want your infrastructure to be setup. If you want your NAS to behave like a NAS, and host multimedia files for your client(s), then you can use either NFS or SMB or both. You...

Yes I'm aware of the 4 year old thread with 50 +1's on it. In that amount of time, surely there have been multiple ideas kicked around internally, and not shared with us.

Network storage should be mounted at the layer you wish to consume it and work with it. In the PVE GUI, Datacenter -> Storage -> Add -> NFS will mount an NFS share in your Proxmox datacenter. Datacenter storage is for your virtual infrastructure. Your only interaction with NFS at this layer is...

This might be a question for reddit /r/plex. Not seeing how Proxmox is involved. Wherever Plex is running, virtual or not, you will have to mount your network storage to the local system, expressed as some local path, and configure your Plex libraries on those path(s). If its...

This is more interesting not because of OP's original question but because of how it is related to the practical max cluster size. pmxcfs works great as-is and the max cluster size, for 99% of people's use, is high enough. Far into the future, what are everyone's ideas for how this could be...
