Is it possible? I tried, but with errors. # pvecm add 10.1.0.11 copy corosync auth key rsync: change_dir "/etc/corosync" failed: No such file or directory (2) rsync: link_stat "/etc/pve/corosync.conf" failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see...

Hi, I have the stable issue. Crystal Disk Mark hangs VM in 100% of cases when VM is launched on PVE 3.4 with kernel 3.10 and VM's disk is qcow2. With kernel 2.6 or any other format of disk no such problem. When I stop the hanged VM I get the next messages: root@hq-vmc1-1:~# qm stop 121 VM still...

In fact, there is a third node in this cluster. This node has only one HDD SATA 250GB. And I watch the similar result on the third node. root@hq-vmc1-3:~# pveversion pve-manager/3.4-3/2fc72fee (running kernel: 2.6.32-37-pve) root@hq-vmc1-3:~# parted /dev/sda print free Model: ServeRA System...

Hi, I have two node cluster with ZFS on each node. And I see very slow work of ZFS On the first node (pve-manager/3.4-3/2fc72fee (running kernel: 2.6.32-37-pve)): root@hq-vmc1-1:/# dd bs=10M count=200 if=/dev/sda of=/dev/null 2097152000 bytes (2.1 GB) copied, 3.55839 s, 589 MB/s...

Hello, After I have added third node to the cluster I have the same messages in syslog. Mar 26 03:24:04 hq-vmc1-3 pveproxy[6332]: problem with client 10.1.0.11; ssl3_read_bytes: ssl handshake failure Mar 26 03:24:04 hq-vmc1-3 pveproxy[6332]: Can't call method "timeout_reset" on an undefined...

Hello, Yesterday I have upgraded to PVE 3.4 from 3.2 and today I have big problems. The load of the node suddenly grew at 12:00. I can’t find the cause. Some servers hang with the next messages: # iotop -d 10 -P Total DISK READ: 21.17 K/s | Total DISK WRITE: 2.82 M/s PID PRIO...

Hi, I tried to implement a Quick Migration using ZFS snapshot/send/receive. It works, but not as fast as I would like. Migration of the server with 1 GB of RAM takes about 1 minute. Almost all of the time is spent on saving, copying and restoring the state of VM. Here is an example of commands...

Hi! It is possible to take snapshots including RAM. But is it possible to create a backup the same manner, including the RAM?

Ok Thanks I'll look for the cause

First of all I've updated all firmwares. What is 'HT'?

No. As I showed before, there are no problem in storage i/o.

You are wrong. I've tested the kernels 10 and 12 and I got exactly the same result as with kernel 14.

YES!!! With this kernel I got exactly the same result as in CentOS. The small area inside the graph is Proxmox with kernel 2.6.32-14-pve. Thanks! :D

I found free benchmark and run on VM on both OS. As you can see, only file i/o is better in Proxmox. I've tested ubuntu 12.04 http://forum.proxmox.com/threads/11248-KVM-performance-on-different-operating-systems?p=61720#post61720 It's performance is closer to CentOS. I know, that there is the...

For the tests I use VM with only one VCPU. Are there any benchmarks for various virtualization subsystems that I could run? I've already tested the storage subsystem, performance is the same in both operation systems.

apt-get upgrade didn't work. I had to run aptitude full-upgrade. Now I have the next: # kvm --version QEMU emulator version 1.1.1 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard # uname -a Linux hq-sr-v1 2.6.32-14-pve #1 SMP Tue Aug 21 08:24:37 CEST 2012 x86_64 GNU/Linux But I still...
