cluster

I tested failover on a new HA ceph cluster all 3 nodes are online but the VM that migrated to the 2nd node from the 1st node will not migrate back to the first node and when I do a manual migration it will not stay in the first node. I removed and re created the HA group and it is still doing...

Hi, everyone. I have some tiny question. Could I check or find logs about connecting cluster successful? In my case, after cluster connect node1,2, I think I should refresh gui window. Is that right? or Do I miss something? Thank for all your attention

Hi All, So I've recently decided to try Proxmox. I'll be honest; it was primarily the Ceph integration that initially sold it to me for the following reasons: In production we use/pay license fees for the Hitachi VSP, and to be honest, it's been very stable over the last 2/3 years. However...

While joining the cluster with node "standby", i used ipv4 adresses only , but we ended up with this: # cat /etc/corosync/corosync.conf logging { debug: off to_syslog: yes } nodelist { node { name: m9 nodeid: 1 quorum_votes: 1 ring0_addr: 83.a.b.c } node { name...

Is it possible to create / join a cluster using an ssh key instead of a password? I would like to turn off password auth for the root user but when trying to join a cluster over the webgui it requires to fill in the root password.

Hello! So we're planning to migrate our vCenter cluster over to Proxmox, and right now we've got a test cluster setup using hardware that's pretty close to what we intend to order. We'd like to use SDN on our new Proxmox cluster, and based on everything I've read in the docs for Proxmox...

Hi all, We are currently running an outdated PVE cluster (version 6.4) consisting of 5 nodes. All VMs and containers are using an external NFS share for both disk storage and backups, mounted at /mnt/pve/NFS. We’ve recently acquired 2 new nodes, and instead of adding them to the existing...

Hello :) Since 24h I'v been banging my head on a problem that appeared by itself yesterday around 12pm according to the logs. Since yesterday, I can't get my cluster to work properly: I have 3 nodes A, B, C. If I turn on nodes A and B or B and C, everything works fine. As soon as I turn on A and...

Homelab-Umgebung. Ich habe ein Proxmox-Cluster mit 2 Proxmox-Servern aufgezogen, kein dritter Quorum-Client mit dazugehängt. Das Cluster war recht einfach einzurichten: cluster/pm1 (alle Vserver zuerst hier) cluster/pm2 (noch kein Vserver hier) Danach habe ich alle Vserver von pm1 nach pm2...

Hi. Bonehead move #126 of the week. Problem: While playing around with joining clusters (using 2 different pve nodes on different IP), I decided to just 'unjoin' the cluster. It wasn't working right, so I deleted the cluster.conf file in the /etc/pve/ folder. When I did this on node #2 (a test...

I am having an issue getting a pfsense DHCP relay to work across my proxmox cluster. My network is as follows: vmbr0 -> 192.168.12.0/24 - home internet (this is where my proxmox clusters are connected to vmbr1 -> 192.168.2.0/24 - virtual interface connected to a smart switch for VLAN 4...

I am curious about linux-kernel native TCP Multipath (not the proxmox iSCSI multipath-tools approach).Anyone here using MPTCP forcing all PVE nodes to open MPTCP sockets instead of TCP? Tentatively, my homelab with PVE cluster nodes with dual SFP+ 10gb uplinks on the same network could in...

Hi, I have a two node cluster configured, home setup. I have a primary node with all the needed services running. The secondary node is actually empty at the moment and not really needed. I plan on building it up, maybe, and have it available to migrate things as needed. For the time being...

Hi everyone, I'm pretty new to Proxmox, and so far, I really like it. Today, I attempted to connect my two OVH servers to run as a cluster over the private NIC. Everything seemed to work fine until I started experiencing timeouts on the second server through the UI. After some troubleshooting, I...

Hi All! Perhaps I am just missing something here but as a cluster do the smtp certificates not sync between nodes or should I be requesting certs for both nodes? ... or is there something else entirely? Thanks! Kris

Hello all! is it possible to create API token which can be used for access only to one/two node in PVE cluster ? thank you

Hello, I'm a bit of a noob in the proxmox world, I've dived into it quite recently, I'm trying to wrap my head (and having a hard time with everything new) about the optimal architecture for my selfhosted home setup. My (foolish?) objective would be to have a proxmox cluster that would allow me...

Hello, I have a two-node cluster and am setting up a separate PVE datacenter. Since Cluster 1 serves different groups, I want to keep the new datacenter completely separate. I need to migrate a VM from Cluster 1 to the new datacenter. Is this possible? Initially, I considered adding the new...

What are the best storage configurations in Proxmox to access a SAN with multiple nodes while ensuring high performance, redundancy, and simultaneous access? How do options like ZFS over iSCSI, ZFS over NVMe/TCP, Ceph compare in terms of latency, scalability, and complexity? The goal is to...

Hi all! I have a pve cluster and a cef storage of 3 nodes. On one node, both OSDs are in the down and out status. I need to replace this node with another node. I added a new node to the proxmox cluster, installed cef. Tell me what are my next steps? Do I need to delete the OSD on the node I...
