Hmmm very stange... I invite you to configure remote logging (for having fresher info if reboots occurs again). And maybe to subscribe official support from Proxmox. It happened only one time ?

Ok. What did you do as special parameters or installs on the servers that doesn't come from PVE ISO installer ? Did the server already worked on an other OS with any problem ? Did you look at hardware logs for over-temperature or manual hard reset ?

Ok. Can you be more specific on your problem please ?

I understand but it is very difficult to put a diagnostic on this. I saw no evidence in the logs. Maybe somebody will have an idea ? What is the hardware of your servers ?

There is no evidence of quorum loss. Corosync does not complains. This there is no a HA protection mecanism involved. Does it happens regularly ?

Oh yes, indeed. thank you for this clarification.

Hello. I think offline is not a concern. The installer uses ISO packages. Personally, I use the ability to fetch the toml configuration by an URL, very practical. Did you read all the doc ? https://pve.proxmox.com/wiki/Automated_Installation

Hello. How many disk do you have per server ? Is there only one 10Gb network for Ceph ? Did you made a comparative test with an other OS or on the host ?

Maybe you are in the case "it's not a bug, it's a feature" :-) If you use HA, be sure to understand the STONITH mecanism. A visual summary : https://www.virtualizationhowto.com/wp-content/smush-webp/2026/02/proxmox-cluster-state-quorum-and-node-majority-1.png.webp Look at Proxmox Cluster State...

Ok. I think we will try to work on it with Yann and Damien. Would you like to join us ? We could team work in a visioconference.

Hello bbgeek17 ! Indeed, that's my intention. And firstly re-test and understand the manual server shutdown on one site.

Hello Aaron. Thank you very much for this explanation. You saved us several hours of extensive tests . Now, do you think there is a workaround if this case occurs, like shutting down each server in a datacenter ? Good job for the documentation. Suggestion of amelioration : - tell that a CEPH...

Indeed, the LRM does the job normally. the problems could be for example when : - joining cluster - joining ceph cluster

Nice to know ! But I would fear to break things in Promxox (cluster fencing for exemple).

Ah do you test cluster fencing ? Personally too and without any problem. But molly-guard is only efficient and enabled in SSH interactive mode. Thus it shouldn't interfere with internal Proxmox mechanisms (non interactive mode). BUT : molly-guard is NO enabled when using WEB shell... too sad :-(
