Hello Forum, we have a strange performance problem running a VM on our 3 node cluster. The vm is a a windows 2003 Standard edition with no virtio driver. Once a day there is a high perfomce database job running on this vm. If we run this vm on our different proxmox hosts we discovered that...

... and what is the correct reference to the stable repository? Do you have an example for a correct sources.list for me? Is the file content below the correct one?

Hello, I've changed our two node cluster into a licensed 3.1 three node cluster but the described behavior is still the same. Every VM for which we newly enable HA (and Autostart) will be moved to Node A on the first start, no matter on which node it was located before. If we disable...

Hello Forum, we bought the community licenses for our 3 node cluster (Proxmox 3.1) and changed the /etc/apt/sources.list. The licenses have been checked and they are valid. If I click the Update->Refresh button in the GUI I receive the following message: My sources.list looks like: What...

Hello Dietmar, thank you for your quick reply. Here are the entries from rgmanager.log Node A (where the vm was originally located when I activated HA) Node B (where the vm has been moved to after clicking HA activate)

Hello, I am running a two node cluster for testing purposes (Vers. 3.0-23 / 957f0862) Currently I am evaluating the HA feature and there I found a strange behavior: Whenever I assign HA to stopped VMs those VMs will be started on node A always even they have been located on node B before. Is...

Hello Guys, thank you very much for your absolutely great piece of software. I’am testing proxmox connected to a failover capable iSCSI SAN (as LVM storage). We are running into little problem if we test the failover feature on the san box. If we start the failover on the san it takes...

That could be a good idea. Do you have any I idea which driver I should use in NT4 vm? There are only a few drivers availabe.

... maybe I have to lock anywhere else. Can somebody explain what 'Status: io-error' in the web interface means in detail? I can't find any according messages in syslog of the vm host or in the eventviewer of the NT4 guest. Is there another place where I can find detailed log messages...

Hello Udo, even writetrough shows the same behaviour. I'am not really sure that the 'assign' trick will work in this case, because even high load the boot disk 'c:\' lets the system freeze. But I will give it a try. Hope this works cause the programmer of the software wrote a lot of hardcoded...

Hi spirit, thank you for your reply. I've tested both cache entries on all drives but with no better results.

I had the job to covert 3 old physical NT4 Servers into Proxmox VM’s cause theay are running a native production software only available under nt4. Two of them are running stable now and I am very happy with it. The third one is even running most of time, but has an issue on heavy disk I/O...

Oh my god. I couldn't find for reading. Thank you very much Dietmar. Now everything is working fine.

Hello Dietmar, I tried it with one of my biggest VMs (2 diskimages 100GB each). And even local backup is very slow. I took nearly 6hrs. My other proxmox box runs this backup in aprox 45 mins including nfs transfer. INFO: starting new backup job: vzdump 111 --remove 0 --mode snapshot...

Hello Dietmar here are my results from my 'bad' box: time dd if=/dev/zero of=/mnt/pve/ubuntu-nfs1-v4/bigfile.txt bs=16k count=2500000 conv=fdatasync 2500000+0 records in 2500000+0 records out 40960000000 bytes (41 GB) copied, 875.575 s, 46.8 MB/s real 14m35.977s user 0m0.405s sys...

Hello Dietmar, I've did it with 32k and with 8k. Here are my results: # time dd if=/dev/zero of=/mnt/pve/ubuntu-nfs1-v4/bigfile.txt bs=32k count=62500 62500+0 records in 62500+0 records out 2048000000 bytes (2.0 GB) copied, 40.9397 s, 50.0 MB/s real 0m44.140s user 0m0.003s sys...

I've made the tests with all three backup modes (suspend, stop and snapshot). All modes are showing the same slow behavior from this box. There are no err-messages in syslog and there were always no concurrent access to the nfs-server. Backups from other systems (Proxmox and not Proxmox) were...

Hello Dietmar, it's definitly a 1GB Nic. But for sure I've teste it with dd. Pls. see below: # time dd if=/dev/zero of=/mnt/pve/ubuntu-nfs1-v4/bigfile.txt bs=1M count=2000 2000+0 records in 2000+0 records out 2097152000 bytes (2.1 GB) copied, 41.8097 s, 50.2 MB/sreal 0m42.643s user...

I have the same issue. I've setup a backup for 4 VM's on a standalone proxmox host. The nfs backup target is a ubuntu 12.04 linux box. For this backup test there were no concurrent accesses to this backup box. I have running also a second proxmox test environment (2 hosts running as cluster...

First of all thank you for your quick reply guys and sorry for my late response but I've been out of office for a couple of days. Your hint about the network separation did the trick. But unfortunately I've a new issue with the online backup. I have one vm with two relative big disks (one ide...
