Hello, We have a Proxmox HA cluster with 3 nodes. Each node has vms on its local storage. We know it's not the best scenario, but we are stuck with it for now, due to our hoster's shortcomings. Anyways, when we try to live migrate a vm from a node's local storage to another node's local...

Hello, I am experimenting with a Proxmox cluster using 3 nodes, and vms on local storage. We also have a shared storage, but due to serious performance problems with this storage, we are trying to get rid of it. I know that shared storage is obviously needed for HA, but we don't have control on...

Hello, I am trying to fully understand a live migration log, and to find settings that enable it to perform better. The operation was a live migration with shared storage (iSCSI) so only the VM state was transferred. I uploaded the migration log on https://pastebin.com/VtDgQUw6 I am trying to...

Hello, We have a Proxmox 7.1 cluster, with 3 nodes. VMs are on LVM over a shared iSCSI storage. Storage access from the nodes reaches between 100 and 400 MiB/s for a sequential read. Cloning a VM is very slow, with 2h 40min spent for cloning a 50 GiB VM (that's a bit more than 5 MiB cloned /...

Hello, I am trying to join a new node to an existing cluster. The cluster has redundant links. The /etc/corosync/corosync.conf file on an existing node looks like this : logging { debug: off to_syslog: yes } nodelist { node { name: pve1 nodeid: 3 quorum_votes: 1...

Hello, I am trying to find more information about Proxmox Cluster networking, and specially the use of ports 22, 5404 and 5405 for intra cluster communication. I feel like the PVE admin guide could be updated with more accurate information (some of which I am contributing in this thread). I...

Hello, I am setting up a Proxmox cluster with 3 servers, and 1 shared iSCSI storage. It seems that I can only access this storage in iscsi mode (I asked a question about this at https://forum.proxmox.com/threads/zfs-via-iscsi.74843/post-378849) With this setup, what are my options for VM...

I setup a Proxmox cluster, 3 nodes with an iSCSI storage. The servers' syslog is spammed by this message every 20 seconds : Mar 22 00:03:34 hostame kernel: sd 8:0:0:0: [sdd] Very big device. Trying to use READ CAPACITY(16). According to some info I found about this message ...
