Node reboot when a disk is removed


Sep 21, 2021
Hi everyone,

I have setup a 3 nodes Proxmox 7.0-11 cluster, each node has 3 HDD drives, the first drive is used for Proxmox and the others are OSDs.
I wanted to test HA by removing the last disk of the first node (which doesn't contain Proxmox), but when I remove it the node reboot.
Is this behavior normal?
Is it related to Proxmox or Ceph, or is it related to the server itself?

Versions :
  • Ceph : 16.2.5
  • Proxmox : 7.0-11

Thanks in advance.
what does the syslog/journal/dmesg say ?
