Hi Spirit Please, let me to do a question: As I soon i will install a PVE with card Intel X520-DA2 10 Gb/s (dual port) for a production environment, i want to get the max speed for my Windows system 2008R2 VM in the network communication, so i want to ask you what recommendations have for this...

Hi PVE team and all people Excuse me if my question is made in the incorrect forum I read in the link "http://pve.proxmox.com/wiki/Ceph_Server" that is recommended the chassis "chenbro". I see in this link a interesting chassis for my target...

You can use these directives in your cluster.conf file: two_node="1" expected_votes="1" These directives will be useful only if your PVE cluster have only two nodes, then, your two nodes never will lose quorum, and you can do anything you want ( goodbye to the command: pvecm e 1 and other...

With the name and IP address that you want It is -force , with only a symbol https://pve.proxmox.com/wiki/Manual:_pvecm Yes, the target is that a PVE node can rejoin to a cluster PVE

Hi to all I need to know about of a software utilitarian where i can run it in Windows Servers for get the info of the flags of cpu. My target is configure the VM of PVE with: - HA - Live migration - CPU type: Host But with two hosts that have different CPUs, and leveraging all flags of CPU...

Wow symmcom, i don't know it, do you have a official Web link that have this information? @Okumba Here a information that will be util for you (see cpulimit and cpuunits): https://pve.proxmox.com/wiki/Manual:_vm.conf

I will tell you about that i am sure: 1- If your processor have 8 cores, and it is distributed in 4 cores with 8 threads, then for each VM each thread will be a core (although in the physical hardware is not so, but the same occurs without virtualization, each OS see a thread of processor as a...

Okumba, LVM as block device only will be util for have a space of disk available for be used as virtual disks for your VMs (or images as it says in the GUI of PVE), Then, it will not have a file system that can be used for others purposes, as backups, templates, ISOs, etc. For get this, you...

About of the amount of RAM, i believe that 6 GB RAM for each VM will be good, but for be very sure, for each VM the best option will be: 1- Start only a VM at the same time in a same PVE host 2- Assign lots of RAM to the VM, it is only for do this test (first apply a shutdown, and after you...

My suggestions: CPU = Host, because enable all his flags cache for performace = writeback, but at risk of losing information if the physical host crashes or is breaks cache for security = writethrough, isn't fast, but is the more sure, you will not lose information, and writethroug also do cache...

Your welcome, and only for be more clear, always that the security of data is the priority, you must use only a of these two options: Directsync: never do cache, only writes in the platters of the disk, and generally used for SAN, iSCSI, etc of high speed communications. In several cases also...

Then don't use LVM. Use a file system (comment: LVM as block device is much quick that a file system): With this example, you will can not to do live-backups of CTs, only of VMs, if you want to do live-backups of CTs and VMs, you must use LVM as file system and with a good space free in the VG...

If you don't have a Hardware RAID with BBU (Backup Battery Unit), for security reasons and gain a better speed for your VMs, use writethrough (you don't lose information if the node crashes, and you will have a buffer of blocks of writes in the physical host using only his free memory) and also...

longhair, if you want a lvm local storage, then you only can have virtual disks for your VMs/CTs, and not as for storage of backups, ISOs, etc., if you are sure that this is that you want, follow these steps by CLI: 1- create a partition in the new disk, for example if is for sdb: shell> cgdisk...

dswartz, thanks for your answer, but i am agree with you, i just asked if mdadm can do multiple reads in parallel (and i expected an answer on whether or not with some fundament), take it easy, is only a forum.... :) Best regards Cesar

Spirit, thanks for the answer, but i have in my PVE nodes these programs: corosync-pve: 1.4.5-1 openais-pve: 1.1.4-3 What is the mission of each one?

Good change for RHEL, but PVE will continue using openais?

If PVE is in a workstation, will be better see the BIOS configuration. I have great satisfactions with these configurations in the BIOS (in several motherboards Asus that are workstation, but with the difference that i always use a Intel processor, i guess that it will have not difference...

Hi Molch Do you have as order of boot, first the HDD where PVE was installed?

Dietmar, correct that this is the 'expected' behavior, but i think that rgmanager need a subsystem of auto recuperation with a set of logical operations for get a successful recovery in this case (be solid as a rock). For other hand, i don't know if i will have some problems, but soon i will...
