corosync

Hi, The title says it all, I've mistakenly rm -R /etc/pve/nodes on a quorated PVE 5.4 2-node cluster. The cluster still runs happily, and pvecm status looks fine and all. But corosync did its job thoroughly removing this directory from the two nodes. I guess the configuration is still in RAM...

Hi, with pve 6 the new corosync version is used. Are there any changes for the amount of cluster nodes in one cluster? If I remember right, for now is the limit 32 nodes, but less are recommendet (amount?). Udo

Hello All, Sorry I know this has been asked before on multiple threads, but I have a slightly different setup then normal and was wondering where to start looking. I have only two nodes currently. Third one is in the works. But for now I have two nodes. PVE01 and PVE02. I had to switch out the...

Hi, I wanted to share my bits with you concerning my home lab cluster made of: - Permanent on-state machines - Ad-hoc machines (in order to reduce power consumption) Of course, besides the "usual" problems of voting (solved by assigning a much higher number of votes to the permanently-on...

Hi, We're having some problems replacing a PVE node in a cluster. These are the steps we've taken so far: Turn off pve03 (out of 3). From pve01, remove pve03 from the cluster with: pvecm delnode pve03 Unrack the hardware. Mount a new server to become the new pve03. Perform clean install of...

I noticed that there's a new feature under the pvecm command to add a qdevice. I have been using Proxmox at home and for clients in a single node local storage configuration for almost a year now, and have been dying to mess with a proper shared storage/two node HA setup. My dream setup would be...

Hi, I use corosync rrp_mode in my cluster, 6 nodes in total. RRP_mode is passive (used this https://pve.proxmox.com/wiki/Separate_Cluster_Network manual while setting it up). When the ring0 interface is disabled on any cluster node it becomes impossible to migrate the VM using ring1 to another...

What method is used to share storage once a host is joined to a new cluster? I've been looking for some sort of config file but haven't been able to find any information about it. Does it use the Corosync network?
