Hi, We have an issue with OVS native VLAN tagging. For a subset of VMs - that should be natively tagged to VLAN 6 - we're unable to get the native VLAN tagging to work. When we hardset the network interface to VLAN6 for the affected VM, everything works fine, but for some reason, if we leave...

Hi All, We have occasional issues across a 20-node cluster that has an NFS share configured as part of the cluster storage (i.e. in /etc/pve/storage.cfg). Basically every so often the NFS server becomes unresponsive - we use it for backups and not for running VMs - but this causes hosts to...

Hi, We run a 20-node production cluster, with just over 1100 VMs. Hosts are typically Intel XEON Scalable processors, with between 768GB-1TB RAM, and between 1-2 RAIDZ3 SSD pools per host - with roughly 10TB usable per pool. We do not have separately installed OS pools i.e. the primary/first...

Hi, We're having a strange issue with inter-VLAN comms/networking between VMs on different VLANs on the same host. We have experienced the same issue on hosts setup with Linux OR OVS bridging - and because of the fact that we segment customer VMs into customer-specific VLANs, we manage VMs...

Hi, We (currently) have a 15-node cluster and adding a number of additional nodes migrating from SmartOS. Each host has between 768GB-1.5TB RAM and either 1or 2 RAIDZ3 pools (with about 13TB of usable storage for each pool) - hosting between 50-100 VMs each, so we have fairly dense hosts...

Hi, We are experiencing issues with IP fragmentation to and from VMs on Proxmox hosts. The issue is impacting ONLY the VMs on all our Proxmox hosts, which VMs all have network interfaces tagged to various VLANs. Note that we have NO issues when pinging from any Proxmox HOST servers to servers...

Hi, We seem to be having some regular and predictable issues with ZFS on our Proxmox hosts - especially under load. Although the following are 2 separate scenarios, we believe that in both cases, the zpool is under load and causes the same negative outcome. In summary, we run a cluster of PVE...

Hi, We have an issue with IP fragmentation not working. We're not exactly sure where the problem lies but it definitely seems to be related to Proxmox (not affecting VMs on SmartOS at all - connected to the same switches etc). Basically, our setup is as follows: 1. Running PVE 6.1 with all...

Hi all, Hope everyone is keeping safe and sane :) We run a fairly busy production Proxmox cluster environment, consisting of 12 nodes (each with between 40-70 VMs, all configured with SSD RAIDZ2 pools, and 72-80 cores - Scalable - with between 640-768GB RAM per node). We are in the process of...
