    [SOLVED] Proxmox VE + Ceph cluster and two datacenters. Too many objects are misplaced; try again later.

    Please help me with your advice. I need to implement fault tolerance at the datacenter level in the Proxmox VE hyperconverged cluster (pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.13-1-pve)) and Ceph Reef 18.2.1. To test future changes, I created a virtual test bench in VirtualBox...

    [SOLVED] Difference in CPU consumption

    Please help me and explain the observed CPU consumption. The ProxmoxVE + Ceph (Hyper-converged Infrastructure) cluster is built on five physical servers. For the test, one virtual machine is running on the server, which shows ~10% CPU load on the Proxmox VE host. Inside the virtual machine, the...
