I have two proxmox nodes in a cluster with directly attached shared storage (HP MSA 2000) where VMs are running. I also set up an NFS share on a separate OpenBSD machine as a storage for vzdump images. The backup process seems to run properly. According to backup logs it takes from 30 minutes to 2 hours for a single VM to back up depending on the VM size. And all VMs are backed up successfully. I measured the writing speed to the NFS share, it is 15-40 mbytes/s, which seems very good. But it turned out that the reading speed from the NFS share is very slow. It is 30-200kbytes/s. I connected to the NFS-share from my ubuntu-machine and tried to read some *.tgz archives from the share to my local hard disk. The reading speed was 10-30 mbytes/s.
What could be the reason for such different results? OS type or something else?
