I would definitely try running the samba server in OpenVZ. That should give you nearly host speed. I've been using it for almost a year - so far without problems.

Ok, and I guess 2.6.18 is not supported in 1.6? At least I see some version conflicts between DRBD kernel and user space tools?

Thanks, is there any other known openvz features missing in 2.6.32? or would you otherwise consider it stable enough for production? Is it stable to do livemigration with bind mounts on 2.6.18? The bind mounts will be placed on DRBD volume. I'm considering sticking to 2.6.18 for now, but it's...

Have you made an "apt-get update"?

Not really yet - I made after-sb-1pri and 2pri use violently-as0p. after-sb-0pri has been set to discard-zero-changes. It seems to resolve which one to drop nicely if you follow the scheme of only running active VMs on one server at normal operation - and still in case you had VMs running on...

Hi, I've upgraded two servers to PVE 1.6. I am trying to migrate an OpenVZ machine but I get this error: /usr/sbin/vzmigrate --online 192.168.31.12 121003 Starting online migration of CT 121003 to 192.168.31.12 Preparing remote node Initializing remote quota Syncing private Live migrating...

Hi, I am trying 1.6 and have upgrade 1 of 2 servers. It all seems fine and I want to move the VMs to the other server to upgrade the second server. I tried online migration, but that is not possible from a 2.6.18 to 2.6.32 kernel? Any way, the migration process seems to stall and when I pressed...

Did a small experiment to make PVE stop migration if trying to online migrate a DRBD based VM. If migration is offline moving the VM is allowed. However a warning is printed telling if DRBD is not running Primary/Primary. The code uses grep and gawk - I should probably sit down and learn a bit...

The hack I can come up with right now - not knowing DRBD very well is to do some sort of: "drbdoverview | grep <PV device>", where PV device could be using pvs-command. I don't know if that would be a safe way to do it. If DRBD disconnects while migrating you would still have a problem.

Hi, I have tested 2.6.18 and DRBD for a few weeks. It has been stable and live migration works like a charm. However today I checked drbd status by coincidence and one of my DRBD volumes apparently had a splitbrain a few days ago. I have followed the guide on pve.proxmox.com, but I see I...

It might be because your policy on the Windows 2003 server does not allow you to shutdown without being logged in. See this page: http://pve.proxmox.com/wiki/Acpi_kvm

You can use this one in stead: dd if=/dev/zero of=/home/10G bs=1M count=10240 oflag=direct Also if you have problems with caching you can limit the amount of RAM Linux has access to so you don't have to write extremely big files. You can do that by adding e.g.: mem=1G to the kernel parameters...

Just ran across a small detail with W2K3 and W2K8 - you need to enable "Allow system to be shut down without having to log on". It can be found in the policy editor here: "Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Shutdown: Allow system to be shut...

Also this one? It seems just to be a bug fix release on top of the 2.6.18-194.3.1 kernel.

DRBD latency measurement (dd if=/dev/zero of=dev/drbdvg1/drbdlvm bs=512 count=1000 oflag=direct) disconnected DRBD (adaptec 5445Z) 54us 1GbE 425us 10GbE (myricom) 120-130us Dolphin 100-110us (2.6.32 kernel) Throughput on my test system was 600MB/s when synchronizing using Myricom. Dolphin I got...

Thank you for a quick reply! I went through the list of openvz kernels. It seems there's a bug fix release for 2.6.18-194.3.1.el5: http://wiki.openvz.org/Download/kernel/rhel5/028stab069.6. Don't know if that also has issues with kvm? Any way - doesn't solve my immediate problem, but I...

I've now tested a Centos installation (2.6.18-194.11.1.el5). This does not suffer the same latency problem. What is the basis of pve-2.6.18 at the moment?

Hi, I have a problem with Dolphin DXH510 latency on the 2.6.18 kernel. DRBD write latency is around 300us. Dolphinics has identified some issues around DMA and interrupt handling - I don't know if it's particularly on my system or if it's a general issue with this kernel. Anybody else with...

Hi, I recently got hold of new hardware and want to run pve-2.6.18. I have noticed in the "/proc/interrupts" that I get a lot of NMI interrupts (below is just after a reboot): CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 CPU8 CPU9...

If the normal "Shutdown"-function in Proxmox webgui works - then it should also shutdown cleanly if the UPS triggers a shutdown of the host. Basically the guest OS need to have ACPI enabled/installed.
