Hi gmed, I probably have the same problem as you and posted this some weeks ago here in the forum. There are others which seem to have the same problem with CIFS. http://forum.proxmox.com/threads/16746-NFS-Performance-Cifs-3-1 In the thread I posted we narrowed a date when a change in proxmox...

Hi, not sure which version of pfsense you are using but I had problems with VirtIO drivers for my ethernet cards. So I changed them back to E1000 because I do not have so much throughput that it would make a difference if I use VirtIO or not. As you said you are using ADSL then you will...

Hi, the source of the VM is my local proxmox server with builtin HDD. I am backing up to a NAS which can only talk cifs... Thanky for the qemu-img command. This is what I didn't know. Unfortunately I do not have enough disk space on my HDD to store the "old" and the "new" qcow2 image. So I...

Ah ok. I now understand what you mean but how do I do that with my qcow2 VMs? Or do I have to change from qcow2 to raw? Changing to raw is not what I want. I have in mind that some things do not work with raw which do with qcow2 (snapshots, backups, live backups or something like that). I...

Sorry for that stupid question: What do you mean iwth "sparse provisioning" and "thin provisioning"? Do you mean the compression when doing backups? --- edit --- So just to make sure you did not meant the compression I tried on another PVE node with other hardware and other VM with: - no...

Hello everybody, I did some more tests on one server. I want to backup a Windows Server 2008R2 running my WSUS. I tried the backup to my NAS first in SNAPSHOT mode and it started with ~20-30% CPU usage and 2-3% IO Delay. When reching 1% backup state the IO Delay dramatically increased up to...

Hi, any news about the performance issue with CIFS? Weekend starts and I can do some more tests - if you have any suggestions ;-) --- edit --- Did another test and tried to do a backup to my windows 7 PC with cifs which has more performance than my small Buffalo NAS but the backup stop like...

Hi, I tried your suggestions but not everythings seems to work. So first I modified the /etc/fstab with Dietmars suggestions and now it looks like this: I rebooted the system. Then I tried a backup of one VM with type SNAPSHOT, GZIP and it finished. The backup has a size of 850MB. Beofore...

I did some further "tests" and tried with backup method SNAPSHOT and tried with LZO and with GZIP and without any compression. The result is the same. While PVE GUI tells me it is doing some backup and it stuck on xx% I went to SSH and checked the folder. There I could find a .dat, .log and .tmp...

Hmm, 11th october could be the point. I shedulded the backups and my last working weekly backup was on 11th october 6am. The last backup I have is from 20th september 6am. Of course I cannot say for sure when I exactly updated ProxmoxVE and what version it has but probably I updated sometime...

Hi, I could not follow you on the complete thread because I am no linux expert but it looks like I have a smiliar "problem" with newer ProxmoxVe 3.x versions. I am using the "Directory" storage model vor Backups: http://pve.proxmox.com/wiki/Storage_Model#Directory I am running a small Buffalo...

Hi, could be related to this: http://forum.proxmox.com/threads/16564-PVE3-1-FreeBSD8-3-pfsense-KVM-Hardware-Virtualization-and-VirtIO-not-possible?highlight=pfsense If FreeNAS is based on FreeBSD 8.3 this could be the reason for not working with AMD64 version but with I386 version.

Hi, I had strange performance problems of the GUI when running my pfsense as CPU type "Sandy Brider" or any other than "Host". The performance with E1000 as NIC was ok - probably this will work if you do not have such much throughput through pfsense. You should test this. If performance is ok...

http://forum.proxmox.com/threads/16564-PVE3-1-FreeBSD8-3-pfsense-KVM-Hardware-Virtualization-and-VirtIO-not-possible In short: FreeBSD 8.3 AMD64 does not run on haswell chipset, FreeBSD i386 does when CPU type is "HOST" and NICs are "VirtIO" and "KVM Harware VirtualizatioN" is enabled.
