Greetings, For several months, our small PVE environment was limited to 1Gbit ethernet and so that was generally our backup performance limiting factor. Then we got old used Infiniband for cheap on eBay. When it worked, you could do Iperf and see 15+ Gbit performance from memory buffer to...

Greetings, We just had a weird event happen when shutting down our third "quorum" host, which is being replaced. We use IPoIB on some old Mellanox IB cards and a Mellanox IB switch. The result was that one of the two remaining hosts went into kernel panic and had to be powercycled. In order...

Hello, I first noticed this when using VZDump to backup a VM sitting on a ZFS filesystem to an NFS share on a different host. I am at the moment trying to migrate a 1 TB virtual disk from a Zpool that I wish to destroy and rebuild. The NFS target is backed by a ZFS file system on a fast SSD...

Hello Group, I find the PVE charts to be handy, especially the Network Traffic graph on the summary page. We have an Infiniband storage network on its own subnet as well as the VMBR0 interface on its own subnet. The graph only seems to show the VMBR0, where the host's IP is bound. Is there a...
