    Hi, I've two W2016 VMs on a single PVE 5.1-36 node. The first, a DC, crashed since the first backup during the backup. The backup most time completes. What I see is most likely a bluescreen but 95% of the console is black only about the first 5% are blue and nothing is readable. A reset does...
  13. Cluster Status

    Hi, as the "current" check_mk plugin for PVE clusters relies on "pvecm" output of PVE v2 (!) I want to do a rewrite of the plugin. I think "pvesh get /cluster/ha/status/current" and "pvesh get /cluster/ha/status/manager_status" may be a good starting point. I found no detailed documentation...
