It's quite possible that your are cpu limited, as currently vm can only use 1 core for 1 virtual disk. Multiple threading (with multiple iothread by disk), should be available soon, I have already send patch to the proxmox dev mailing list.

simply use a different subnet like for example 192.168.0.0/24 with 192.168.0.1 && 192.168.0.2 for your server 25g && backup 10gb card.

more than one OSE per nvme will not help. non PLP are really like 500iops 4k write vs 20000iops for plp drive. At minimum, use cache=writeback, it should help to avoid small write when possible (merging small adjacent writes to big write)

Hi, For people sleeping at the hotel of the conference the day before, anybody interested to drink a beer ?

no, it's local on the node.

at minimum, if you use your arista as exit-node, (advertising the default route from arista) you should remove "exitnodes proxmox1-4,proxmox1-3,proxmox1-1" and peer with your arista router "peers proxmox1ip, proxmox2ip, proxmox3ip, aristaip" snat should be done on your arista too

that's not true, CRM also open/close/update watchdog https://git.proxmox.com/?p=pve-ha-manager.git;a=blob;f=src/PVE/HA/CRM.pm;h=9b80b73f694062f4a82eed59ea601314daa5ad59;hb=HEAD both crm && lrm are connected through the watchdog-muxer

1) on each node : systemctl stop pve-ha-lrm then (when all lrm are down) 2) on each node: systemctl stop pve-ha-crm

proxmoxer is a client lib (a wrapper to proxmox rest api), why do you need to use it on pve node directly ?

don't seem to be a FS, but more an s3 like object storage, it'll not work

It's use for any qcow2 storage, including file storage. (local,nfs,...). External snapshot allow snap/delete snap without interruption. Current internal snapshot freeze the vm when deleting snapshot for example.

(I forgot to say that for snapshot, we use qcow2 sub-allocated cluster (l2_extended=on) with 128k cluster size, so metadatas are 32x smaller than base image (64k cluster without suballocated cluster). around 4MB memory for 1TB image https://www.youtube.com/watch?v=NfgLCdtkRus Also, the memory...

the cache value is a max value, it's only allocated when you need to load specific metadatas (and unused metadatas are flushed after 10min). It's not too much different than zfs btw, where you need memory to handle metadatas too. so , yes, if you read full disk with 8TB datas in less than...
