  1. [SOLVED] Server crashes since upgrade to 6.1-8

    Hi, in this case for 6GB (perhaps too much for an 16GB-server): cat /etc/modprobe.d/zfs.conf options zfs zfs_arc_min=6442450944 options zfs zfs_arc_max=6442450944 # # after changes it's important to run # update-initramfs -u # and reboot Udo
  2. [SOLVED] Server crashes since upgrade to 6.1-8

  8. Proxmox legt alle VM‘s lahm

    Hi, das lässt sich nur dadurch erklären, dass Du die Clustercommunikatin des Produktions-Cluster gestört hast (wie andere schon vermutet haben. durch gleiche IP?). Wenn eine Node kein Quorum hat, fährt sie alle VMs runter in der Annahme, dass sie auf den verbleibenen Nodes (mit Quorum) neu...

    Hi, I'm have two cluster where I upgrade the nodes step by step. If I try to open an console from an VM on another clusternode (not where I logged in), I got an Authentication failed. The console is working fine on nodes where pve5 is running. Logged in -> open console on pve5 -> pve5 =...
