    Hi there...

    I have 2 PVE nodes and 5 servers as CEPH Storage, also building under PVE Servers.
    So I have two cluster:
    1 cluster with 2 PVE nodes, named PROXMOX01 and PROXMOX02.
    * PROXMOX01 runs proxmox-ve: 5.3-1 (running kernel: 4.15.18-11-pve) pve-manager: 5.3-11 (running version: 5.3-11/d4907f84)
    * PROXMOX02 runs proxmox-ve: 5.3-1 (running kernel: 4.15.18-11-pve) pve-manager: 5.3-11 (running version: 5.3-11/d4907f84), as well!

    1 cluster with 5 PVE nodes (previously 6 PVE nodes), which is a CEPH Storage.

    I have lost one of the nodes on Cluster CEPH Storage.
    Now, in PROXMOX01 web gui, I was able to browser ceph storage, just accessing NODE -> ceph-storage
    (ceph-storage is the ID in storage.cfg)
    But, when try do this in PROXMOX02, in web gui, I get communication failure(0).
    But, yet, inside PROXMOX02 shell, the command:
    pvesm list ceph-storage
    works, it's took a while but give the list of VM's images...
    I already try:
    - Update the PROXMOX02 node
    - Updacerts in PROXMOX02 - pvecm updatecerts -f

    That's the storage.cfg file:
    rbd: ceph-storage
    content images
    krbd 0
    monhost 10.10.10.100;10.10.10.110;10.10.10.120;10.10.10.130;10.10.10.150
    pool VMPOOL1
    username admin

    rbd: ceph-ct
    content rootdir
    krbd 1
    monhost 10.10.10.100;10.10.10.110;10.10.10.120;10.10.10.30;10.10.10.150
    pool VMPOOL1
    username admin

    The command above works fine:
    /usr/bin/rados -p VMPOOL1 -m 10.10.10.100,10.10.10.110,10.10.10.120,10.10.10.130,10.10.10.150 -n client.admin --keyring /etc/pve/priv/ceph/ceph-storage.keyring --auth_supported cephx df

    Is there something else I could try to solve this issue?

    Thanks

    Never mind! After the above actions, I forget to restart the PROXMOX02 node.
    After do it that, everything is ok!
    Thanks
