if you backup storage is slow (or if you are limited with network bandwidth), it can slow down vm write during the backup, if a block is not yet saved. (it's not related to ceph, this is the same for any kind of storage) You can try to enable...
I had trid ocfs2 10year ago during 1~2 year, and I had a lot of lock problem if 1node of the cluster was going down. (like full cluster lock during 1~2min, the time that the lock was released). I have done benchmark test last year, and write...
seem than freebsd have fixed the checksum bug with virtio-net recently (september 2015 / freebsd15)

I don't known if it's already available in pfsense/opensense...
Hi dominik, I'm going to test with a H200 soon.
have asked to nvidia support for ai enterprise support (and also about MIG mode not working with windows vms)
a difference with snapshot mode is that the qemu agent is doing a fs-freeze/fs-thawt before the backup, so maybe you can try to disable this ? (they are an vm config option in vm guest agent config).
also, not sure that it could help, if you...
move the file (delete the vm config on source node) to be sure to not restart it again on old01 by mistake, when it's running on NEW01, or you'll break your vm filesystem
the vm traffic is goinf through the vxlan (vxlan_remoteip ...), so it's use peers ip address.
if you want to split management && vm traffic on 2 nic, you need to setup 2 differents ip address on each host on different subnet. (1 for management...
About pdm, Disaster recovery is on the roadmap. Evpn central configuration is already available in 1.0. If you need other vpn mesh, they need to be added in pve sdn first
maybe your hardware raid have writeback cache ?
what is your ssd model ? datacenter grade ssd with supercapacitor ? (zfs will run poorly on consumer ssd).
0% pressure is totally fine, it should be 0% to have good performance.
you shouldn't use consumer ssd like Samsung evo with zfs. zfs is doing synchronous write, and consumer ssd don't have a supercapacitor to keep sync writes in memory cache before writing the nand cell. (it's really something like 200~400iops on...
"I'm assuming defining static routes to get back to the VMs from external is perfectly okay, but we're going to see about getting bgp set up on our switches"
If you want to reach the evpn network from outside, if need indeed routes to the evpn...
