This morning we had a major incident, all our proxmox nodes where fenced at the same time.
In the log, this seems to be the problem:
Sep 1 10:50:14 hostname kernel: [932130.006753] show_signal_msg: 6 callbacks suppressed
Sep 1 10:50:14 hostname kernel: [932130.006757]...
We are using 2 bond interfaces for storage (2x10Gb) and a trunk for the VMs (2x10Gb).
We want to split the trunk for the VM in VLAN bridges so we can assign them to our VMs.
