New update on the progress: Added on the kernel's grub start args max_loop=255 and started the bare metal system in the try to increase the max loop devices on the system and overcome this limitation. After, the container starting/stopping operations are taking considerable longer but what...

Thanks for the feedback. I'm pretty sure that I'm not the only one trying to run high number of CT on a prox box. Regarding the LVM, I haven't tried that but for plain and quick manipulation of image files I'd rather stay on file storage backend because on the current storage there is also...

Hello guys, I have a dell 2950 server with one 120 ssd drive and a 1Tb 8 drives array in raid50 for local storage 64GB of RAM and 2xX5460 . I have just installed the latest version of pve in the attempt to run a test environment for client api calls emulation on a software development project...

Hey guys, I am encountering the same error with a much up-2-date version of pve. Environment details: 7 prox nodes running the same version each prox node connects via dual 10 Gbit NIC with 2 switches and forms an MLAG Po each traffic type (also cluster -corosync vlan) separated/designated...

Hello Alwin, Please pay attention to my post, I use an external ceph cluster which is up 2 date, and the same ceph cluster which I used (but on different pool) on pve 4.x branch before the 5.x upgrade. The ceph version on the cluster is 10.2.10-0ubuntu0.16.04.1. Regarding the pve' the system...

Hi Guys, I just reinstalled a server after some disk changes, with proxmox, updated to latest version, rejoined the cluster and try to migrate some disk's VM from an external ceph cluster to the new server which is also configured to share a raid volume over nfs to all other servers. I have...

1. 1 socket and 10 cores - that is the correct way 2. enable numa 3. I am talking about the hypervisor settings and not VMs. 4. be sure to have latest updates of qemu-kvm versions from pve repository

Hi, I always run on virtio drivers because this is the kind of driver that delivers the max iops on the virtual system, at least if this is what you're hunting for. My guess is to go for the 4.2.6-1 kernel branch, I think I just recently upgrade to latest 33 release of the 6 minor version and...

did you try using latest 4.2.6.-1 release ? give more info about your setup.

dietmar, let me give you an example of use case for such requirements. Consider the following case - 5 proxmox nodes HA cluster setup, each with 1 x SSD Kingston V300 @ 120G for journal and 1 x Intel 750 400G NVMe drives. The cluster is still under performance benchmark and testing and testing...

Might I make a comment on the vm.dirty_background_ratio and vm.dirty_ratio ? I would see these value not being very appropriate for a hypervisor host, but more like vm.dirty_background_ratio = 10 and vm.dirty_ratio =5 as data should be flushed much faster to disk source and avoiding the...

Solution can be found at the following thread post: http://forum.proxmox.com/threads/20372-Linux-guest-problems-on-new-Haswell-EP-processors/page2? This is for anybody having the nerves to read all this.

@ e100 - tested every possible setting, even ISCSI, hot plug disabled, all same results. But while some are still frying the fish, other stubborn people prefer to have a solid solution to this bug and use virtio (the best performance) without any issue. :D As a tested solution to this issue...

@ Spirit: I can't change nor test this on to this systems because are production envs and my main concern is not to have sleepless nights due to this stupid bug, which I already had plenty. Separately, I have a different env running on Core i7 socket 2011 v1 CPUs and never had encountered...

As said, I returned with more info on the topic in order to shed some light on the gathered research I've manage to do so far. Considering my last post, I have focused on the way the internal disk scheduler is set, from default values towards changing it to deadline on all VMs. This has...

Yes, All up to date, bios, firmwares, HW raid firmwares. How can I send a PM message to you on this forum? I can't locate the PM button to contact you on a quick chat/call on private. I wouldn't post into this forum like chat message, to spam it, and return to the thread once I get some...

Thank you for sharing this very useful information ! My servers are running H730 Mini (MegaRAID SAS-3 3108 [Invader] (rev 02)), which is based, if not mistaking, on the 93xx LSI branch cards. Although, it doesn't apply. As I described I am running 2 setup, different locations, one with local...

Still, that doesn't mean the issue doesn't exist ;) There is a sure difference between my 730xd's (running also on local and remote storage) and yours r630's in terms of chipset and used CPUs, but I am having a hard time believing that the CPUs instruction set on my 2630's v3 is so new that it...

Where in the world did you find backports pve kernel ? Besides the rest, I've got these 2 in source.list: deb http://download.proxmox.com/debian wheezy pve-no-subscription deb http://http.debian.net/debian wheezy-backports main Are you running on the bare metal server directly the stock...

@ spirit - Yes, it is the default value set, hotplug enabled (Disk Network and USB), are you suggesting something ? :D @ robhost - I said I am not using OpenVZ, as pointed out in that separate link I provided, fully describing the issue. But as on the other hand I am not running only debian to...
