do you have a granular monitoring (prometheus,...) which can check bandwidth every second ? don't trust average.
do you have also checked your switch port buffer stats ?
if it was a kernel bug, you'll have too on your 10gbit nic.
I'm running...
but you have packet loss, this is even worse. (you can look at corosync stats too
yes, definitively
the recommandations is to have dedicated links for corosync

I don't think that microcode has never been in pe-firmware package. It's always the debian package. (and debian can be a little bit slow to update them)
you can try the firmware from debian testing:
http://ftp.de.debian.org/debian/pool/non-free-firmware/a/amd64-microcode/amd64-microcode_3.20251202.1_amd64.deb
(or upgrade your bios if your vendor provide it)
basically, if you have network saturation, the latency increase, and corosync remove the node from the cluster. (down/up don't mean that the physical link is flapping, it's simply that the node where you are checking the log, don't have a...
Well, you cant just pass all flags blindly. Some Windows versions can crash, some flags like tlbflush can have performance impact dépending of the workload,....
From the analysis until now, the IO pressure seems to be a cosmetic issue or rather accounting issue in the kernel. QEMU switched to using io_uring for event loops with QEMU 10.2. The issue appears in combination with IO threads, where a blocking...

the thing is that the host itself don't mount the rbd. It's done directly by each qemu process. the librbd is inside qemu, and this is the qemu process which is doing to connections to monitor && osd.
(with kbrd it's different, as it's done by...
if you have a vyos router, the best way is to peer with evpn with other proxmox nodes. (1 peer by vrf. 1 proxmox each zone is a vrf).
if your coke tenant is a layer2 behind vyos, vyos should announce their ip/mac inside the evpn zone.
It's really done when the qemu process is starting when librbd is initialized. (like other tuning that you can do in ceph.conf). It could be possible to pass params to qemu commandline, but qemu rbd driver have limitations of parameters that you...
I 'm not sure that hook can work with live migration, as the arp entry need to be set after source vm stop (the arp entry need to be flushed from source horst) and before the resume of the target vm.
This is a thing that we should implemented...
I finally solved problem thank u for help
The root was my network devices configurated as stack and corosync was connected to different units, thats caused link flapping, when i connected to 1 unit problem was gone
