Hi, on cluster (drdb) with 2 node (master, slave), is possible have 2 version of proxmox? (es. 1.5 and 1.6). If I have 2 proxmox with 1.5, can I upgrade one to 1.6? Thanks, Francesco

Ok, I understand I've already done the test with a xfs partition, and the result was nearly 6000 / s fsync. My only question is why fsync varies depending on the filesystem? The test (pveperf) not based on raw partitions? Thanks Francesco

Thanks Tom, no VM is installed and system is very idle. With 2.6.35 fsync downgrade to 99 for second. With this hardware, fsync should be a lot more? (over 1000?) We need more information to resolve the problem? Bye Francesco
