Thanks for the comment Adam, but I missed your point there, your example shows 291MB/s, I am getting ~330MB/s, but on iperf I can move 11gb in close to 10 seconds. Your higher end CPU appears to show the same encryption bottle neck as mine or worse. Anyone know why I can test out AES-128-GCM @...

ext4 on lvm is the default install from the iso.... lvm-thin adds some other handy features that are probably preferred.... if you decide on thin, look for that option in the storage gui when you add the directory.

Some more testing on this.... still not sure on if openssl is using aes-ni, but found other details: root@pve1:~# apt-get install -y gnutls-bin root@pve1:~# gnutls-cli --benchmark-ciphers Checking cipher-MAC combinations, payload size: 16384 SALSA20-256-SHA1 0.21 GB/sec...

ouch... arcfour gave ~150mb/s on a scp, so that didnt work well. The cpu is a Xeon e5-2620 v3 (6core/2.4-3.2ghz), I know its low end, but appears to support most major features, was spec'd because VM workload did not require much, its only 1 small centos, a 2k8, and an xp, but I need fast sync...

And I see pve-zsync is also encrypting... is there a way to disable encryption for zfs send? doh! - of course the send is piping through ssh, any thoughts on sending through netcat instead?.... Im not big on perl, so not sure how far I can get on zsync.

Shutdown all VMs, Run pveperf /mnt/raid6dir to check your baseline reads. Run this to check writes: dd if=/dev/zero of=/mnt/raid6/somefile bs=1024k count=8192 conv=fdatasync Run "top" on PVE as you start your VM.... watch gui for io delay graph on host machine summary. For linux VM raid6...

I have 2 Dell R730, 1cpu, 32ram, 6x ssd raid, and 3 different 10gb nics to choose from, going through a Nortel 5530 with 2x 10gb XFP, 9k frames, and switch ports VLAN'd (untagged) from all other ports. iperf tests look great: dd performance on the box locally is good: But an scp from box to...

Note for others in this situation on qcow files can convert more quickly using an nbd device. Pre-build your vm in the gui, then overwrite the zfs dev with dd- modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 /mnt/oldstorage/images/100/vm-100-disk-1.qcow2 dd if=/dev/nbd0...

I am having the same issue also, 2 VMs backup just fine 100% always, but one always fails with the same vma_queue write error at around 75%. Backing up to local 5TB sata drive. Running PVE 4.2-15/6669ad2c kernel: 4.4.13-1-pve

Just curious as a lot of the facebook servers seem to be hitting the grey market now. I know power and rack size can be an issue if you dont buy the whole rack, but these might be good lab machines for testing.

What is your storage backing? For reference: I was having a lot of trouble on a 2012 r2 with current 0.1.102 drivers, it would have really long boot times and sometimes crash before booting. I went back to virtio version 62.72.104.10200 and it has not had any trouble since. Running on qcow on...

So I got a pair of servers loaded up, the only thing I cant piece together is config sync, in the wiki it seems to imply vm confs are in /var/lib/pve-zsync/ but it appears that is not setup automatically, and I am not sure how to set that up as the config location. What are you using to keep...

Cool... Im going to try to light up a test lab on a couple optiplex with SSD, is that possible on a single drive? I just pick the ZFS option on the installer- right? Or does it need separate storage media for the zsync directory?

I figured 3 would be needed.... and I could do that using my retired R510, but I wouldnt want to rely on it for storage, and am trying to avoid some sort of expensive NAS/SAN in the mix. So it sounds like zsync is what I need to keep my data "near realtime" on both boxes, and easily spin back...

I am thinking of getting a Standard subscription package to aide in setup of some VMs that have hardware pass-thru needs, and CEPH setup. Would support cover that? Or are there disclaimers/exclusions as to what cases can be used for?

Or 3 nodes?.... background: Current setup: 2 PVE 1.7 hosts (no cluster) Dell R510 2x 80gb Windows VM + 1x 80gb CentOS VM (not ct) Supermicro server: 2x 30GB Centos CT, Installed in same rack, no HA. Will be upgrading these to a pair of Dell R730, and want to setup 1 in another building over a...

I am trying to install to a Dell R720xd, with a single SSD on the H710 controller. I have tried both pve4.0 and 4.1, with 4 different methods of writing the USB and they all fail. Depending on whether I use iso emulation, or just write the image to the usb, I get different behavior. First...

I removed the size parameter, same behavior. file -s shows NTFS, it was formatted from a windows 7 workstation.

I have done this many times, and usually I dont need to move the disk to another machine, so it just works, but in this case, I cannot go back and forth from physical to vm with my USB drive, I wonder if it is a problem with GPT.... although I can initialize it as GPT in the guest and start...

I am passing a 4TB USB drive to a Windows 2008 VM: virtio2: /dev/sdc,media=disk,cache=writeback,snapshot=off,backup=no,size=4000G This disk was preformatted NTFS on a windows workstation, but when I connect it to the VM, it sees it as an un-initialized disk, and asks if I want to use a GPT or...
