Hello Everyone, Right now I am finally jumping into my Proxmox Ceph Cluster Project I have been waiting to work on for months now. So far, things have been going smoothly in terms of getting the Cluster created, however I am somewhat unsure as to whether I have a proper understanding of the...

Hello guys I had a problem using proxmox in my Debian machine. my problem are in the web GUI when I want to create a VM it shows a warning that the node seems to be offline like this image. but if I navigate to the node information it says online and have uptime like this image. and this...

Hi, our new cluster is being prepaired for use and while slowly starting to use the cluster i see some messages in syslog: Dec 25 06:27:52 prxa06 pmxcfs[4868]: [dcdb] notice: data verification successful Dec 25 06:34:26 prxa06 corosync[5041]: [TOTEM ] Retransmit List: b819f Dec 25 06:35:35...

Hey all, I observed a strange reboot off all my cluster nodes as soon as on one specific host cororsync is restarted or this host rebooted. I have 7 hosts in one cluster Corosync has 2 links configured. ring0 is on a separate network on separate switch. ring1 is shared as VLAN over 10G fiber...

What’s the expected behavior here? I have a 3-node cluster with dedicated physical corosync network, and a 2nd faster network for storage and networking. The corosync network is configured to failover to the fast network if interrupted. High availability is configured on guests with shared...

Hello, after upgrading from pve6 to pve7, the syslog of both servers is spammed with: corosync[8001]: [KNET ] nsscrypto: Incorrect packet size. After some googleing I haven't found a solution yet. Hopfefully someone can help. Edit (Solution): Related corosync github issue The reason was the...

Hello all, Before I begin I want to thank you all for your great posts/replies here. We've been using Proxmox for over 1 year and have never made a post as we've always found the answers here by searching (and that could be the case here, but I'm currently on vacation and wife gonna kill me if...

We upgraded the proxmox to 7. with latest ceph. and almost everything back to normal.. Currently our main network is the same network with the corosync and consists of 11 nodes, (4 of them with ceph) We plan to double the server count in the near future and i thinking of moving the corosync...

Hello, Today our cluster lost synchronization. Most of the nodes were shown as offline or unknown. The nodes were up but every node could see only itself and few other nodes. Restarting the pve-cluster and corosync didn't help so we brought everything down and started them one by one. For most...

Hi, I tried to upgrade a 6 nodes pve7 cluster yesterday. We use Ceph and HA for all VMs. I was able to upgrade 4 nodes without issue. But on the fifth node, I lost the whole cluster. All nodes rebooted ! Syslogs for nodes 22 to 27 : update ok for nodes 22,23,24 and 27 upgrade of node 25...

Hello, what is the best choice for a 12-node cluster? 1) Upgrade nodes one by one. Initially, the newly upgraded node(s) will not have be quorate on their own. Once at least half of the nodes plus one have been upgraded, the upgraded partition will become quorate and the not-yet-upgraded...

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...

Hi All, I appreciate any feedback I get here. I have an existing 5 node cluster. It runs Ceph, but I dont believe this is applicable to the situation, but thought to mention it. I also have an existing 3 node cluster. No shared storage. I've migrated everything away from the 3 node cluster and...

Hello everyone, we're running a 48 node pve cluster with this setup: AMD EPYC 7402P, 512GB Memory, Intel X520-DA2 or Mellanox Connect X3 NIC, Ceph Pool with only NVMe, 2x 10Gbit/s interfaces (for cluster traffic) + 2x 1G (for public traffic). As a few others have recently reported in the forum...

Hi, tonight is the second time I face a huge problem when trying to add a node to my existing cluster. My cluster contains approximately 15 nodes, I use CEPH as storage and everything is working pretty good. All our nodes and "future" nodes FQDN are contained in /etc/hosts like : -...

Dear all, I am currently dealing with a problem in a hyperconverged (ceph) where the whole cluster reboots seemingly at random. Every single one (of the total of seven) node resets at the same time. I am suspecting corosync to not be able to communicate properly. This problem has only popped up...
