krbd

I’m running a 5-node Proxmox cluster on version 7.4.19 with two storage pools: one on spindle drives and the other on SSDs. Both pools host live VMs, but performance is slower than expected, with high IOWait states. I’ve read that enabling KRBD can improve performance, but I haven’t found clear...

We recently enable kRBD (tick the KRBD box in storage configuration) for our running cluster. Faster IO was the main reason, We record 30% gain in reads/writes in all VM running in writeback cache mode. But then a couple of VMs disks needed to be resized. In both cases disks went to 0 bytes...

Hi all, I just upgraded my cluster to Proxmox VE 6.1 and wanted to give the updated krbd integration a spin. So, I set my rbd storage to use krbd and then tried to migrate a vm to a different node. This is what I got: 2019-12-08 11:49:22 starting migration of VM 211 to node 'srv01'...

Hi I have a 7 Node Cluster with CEPH - RBD. I have a lot of existing VM's running on the cluster and decided to try out containers. I noticed that KRBD needs to be enabled to do that. I went and tick the KRBD box and added "Container" to content together with "Disk Image" in RBD. I then...

For using proxmox 4.2 with an existing jewel cluster, from the ceph jewel release notes, you need "rbd default features = 1" in the client section of ceph.conf. but i dont see a ceph.conf anywhere. is there somewhere else this can be set? in a test cluster of virtual machines, did proxmox 4.2...
