With respect to Waltar, I would hope you would do more research then "a dude on the forum" before you make capital decisions. I dont even understand what you are trying to say. what gui? if you mean PVE, yes you can, but you probably would WANT to use the CLI because there is more control there...

I dont believe this is true. My understanding is that there isnt a LOGICAL difference to the guest at all, and the only reason the options exists at all (other than its just a part of the api) is to allow simulation of a multisocket system in a vm, which is useful in some licensed environments...

Not the relevant factor. Not the relevant factor either ;) mount the same filesystem using nfs and rerun your benchmark. Neither I nor anyone else is saying virtiofs is not fast ENOUGH for any given application, just that it's observably slower than other methods of connection.

Yes. have your servers in a cluster. If you want to have a more formalized method for a true DR, you would need to keep your servers synchronized, either synchronously or on a periodic basis (data and configuration) along with a matching internal IP structure and NAT to repoint your VMs at...

Thats an interesting way of putting it. "Professional" implies a person or company who specializes in a particular application or solution (as in, do it for a living, hence the "profession"). If that isnt you, nor someone else- it wouldnt be a professional solution to begin with. Where did you...

The link you presented offers a discussion on how a hypervisor could use the provided glue to copy a presented virtiofs resource to a destination. In order for this to be useful, a product such as proxmox would have to make provisions to check if OTHER guests are connected to it, quiesce any...

so, if I understand correctly, you're asking the forum for instruction on how to circumvent this other products protection mechanism. Maybe you can see how that's probably the wrong place to do so. In any case, when you move a raw device it remains the same on the destination. The only pointer...

at the risk of questioning your reading comprehension, I'll restate: number of nodes is irrelevant for usable capacity ratio calculation.

it is (calculation; choice is a separate matter since the number of nodes is an arbitrary number you chose.) Correct, but you're not considering the consequences in their totality. Ceph is designed to maintain its full resilience even in the event of a failure. if an OSD fails, it will...

start reading :) https://docs.ceph.com/en/latest/start/beginners-guide/ when you read the above it will start making sense. No. storage utilization follows your deployed crush rules, which will dictate HOW data is written to disks, no matter how many disks or nodes you deploy. whats cool is...

why are you surprised? you are asking about matters specific to a different product. why not ask their customer support?

naturally. its a separate filesystem. PBS doesnt use snapshots. You cant "configure" that which is not possible to do. virtiofs is like any other external mounts- nfs, iscsi, whatever- its outside the scope of the parent hypervisor.

I have no idea what is meant by this. you need a MINIMUM of 3 osd nodes. the USABLE CAPACITY will be 1/3 of the deployed disk capacity. The reason 3 nodes can be insufficient for optimal operation is because there is no target for rebalance/self heal in case of a node failure, so you really...

I doubt that. Truenas enterprise isnt "cheap." Fair. I hope you understand that not many share your opinion. dual controllers with a single disk set is the gold standard for HA precisely BECAUSE it avoids the potential for split brains- there is only one set of disks. YOU might not consider it...

Please provide a link. Truenas Enterprise has touted true HA since 2022; As I am not affiliated with them I cant speak for the technicals and would be glad for the education. Async replication has been and is available for the free product. its also available in pve directly or any CoW...

the more you feel certain of something, the more likely you are to fall victim to the dunning-kreuger effect. This isnt the Truenas forum so I wont go into detail, but suffice to say your conclusions arent... supported by data.

I think you might want to read this: https://www.truenas.com/truenas-enterprise/

boot on a mirror and payload on striped mirrors is best practice. You dont need (or benefit) from a slog or l2arc for your usecase. No change. The integration into pve has some issues, but that aside there are many reports of issues that suggest that there are still maturity issues. I...

I replicated thes OPs test ("Allow Direct IO" enabled.) tldr: can confirm. On this test, virtiofs delivers 38.7% iops vs NFS. Pretty substantial difference. to the filesystem mounted via virtiofs: fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=./test...
