That's logically because would you develop (not only maintain) a plugin for another software component which isn't from Proxmox? Shall Linbit or Ceph project provides PVE GUI pages to manage their cluster? This isn't realistic. My experience for best practice is a well documented API (for...

Hi together I think you aren't talking from same issue. Tom has right concerning the plugin for current version. It's working because Linbit took it from Proxmox's repo just as is. But for mid and long term I support Titux's statement. Linbit has no interest develop the plugin in future. We...

LnxBil Thanks for your tip. For what? For PBX (Asterisk), some phone (via PoE), Switche and router. I need to run PBX infrastructure for about 60 min. after power loss. There are two reasons: a) evacuation announcement to phones via multicast and b) emergency call from elevators to support...

For most cases / vms you are right. Orderly shutdown is necessary for all servers at the end. I only want to let run the asterisk based PBX (+switch/+router) as long UPC reaches 10% of power (ca. 1 hour). Running "half" cluster combined with manual recovery (important) isn't so risky. In my...

Thanks for your answer. I know about HA 4 functionality but I hesitate to use it caused by some disadvantages. The manual transfer from a "dead" server to a running server within a cluster is secure, because I know if a server is really down or not. So this "half" HA allows running one server...

I run a cluster with three nodes (quorum is given) normally. The VM's are synchronized with DRBD or on NAS share (uncritical VMs). HA groups aren't used at the moment (I'm still in trial and learning status with this functionality.) Yesterday I had a crash on node2 caused by a driver. I was...
