raid

Hello I know that the better way to use ZFS is with no HW RAID, but I have an C6220 with lsi 9265 raid card. It's a bit difficult to flash it to get IT-MODE so I have build and RAID10 (with 6 SSD kingston DC) and install proxmox in ZFS 0 over the virtual disk. I was creating the nagio RAID...

Hello community :) I currently plan on using proxmox to build my new virtualization environment. Before I actually rent the server for my project, I want to ask you about the storage possibilities I've got. What I'll order: 4x 480GB DC SSD So question is: What's the best way to build this...

I'm setting up a new server with proxmox 5, I ran some tests on a older machine and finally got my new one today. I'm using an IBM Thinksystem SR550 It has 2 raid controllers, 1. M.2 riser kit on motherboard (2x 32Gb Raid 1) 2. Thinksystem raid 930-8i 2Gb cache (shows up in lspci as: LSI...

I haven't yet tried a 5.0 installation, but I was wondering if the PVE installer allows creation of Linux software RAID and then installation of PVE on that RAID? On 4.x, I had to do a manual install of generic Debian first, then (hard to remember, it has been a few years ago) do something else...

Hi, most of our servers have 6-8 SSD Hard drives with RAID Controller that include 1GB-2GB Cache now, the question is what is the recommended configuration for Proxmox 5 focus on Availability and best performance: 1. Hardware RAID 10? 2. ZFS with RAID10? 3. Hardware RAID1 with ZFS Raid0? 4...

Hallo, ich werde Proxmox 5 auf einem neuen Server installieren. Die Büchse hat neben einer SSD für das OS einen LSI Megaraid Controller mit 4x4TB Platten daran. Was ist die aktuelle Empfehlung für die Konfiguration? Sollte ich ein RAID 5 oder 10 am Controller einrichten, oder die Platten als...

Hi I'm going to set up a single machine used for VM's soon. I think i have all the hardware figured out except for the hard-drives which i would like some recommendations for. As this is going to be a quite simple setup i would prefer local storage - easier and cheaper. My initial plan was...

Hello, I am currently trying to create a VM/CT in proxmox, however I get the following error during machine creation: TASK ERROR: no such volume group 'pve' Upon some checking, I noticed that the Local-lvm has no Space at all allocated to it. When I installed this instance, I setup a SW raid...

I'm going to install Proxmox as the hypervisor for my home server and I was wondering what the community would recommend as my drive configuration. I've decided to store my data on a bunch of spinning disks using BTRFS. But on what should I install Proxmox and my VMs and containers...

Hi there, We are having trouble with a 3 nodes cluster that is rebooting every node simultaneously every few days. We are using OVH servers, so only unicast is available, OVH vracks being more expensive and we dont need more than 3 nodes. We are using software RAID with SSD drives and our VMs...

Hi, It is possible to install Proxmox 4.2 on a ZFS raid 1 on a two pendrives to get some redundancy? Obviusly is only a boot disk, VM resides on a shared storage SAN. If possible, what is the procedure on a disk fail? Greetings.

I am testing a new PVE install and would like to use ZRAID-1 when installing, however this uses all available space (1TBx3 disks). I'd like to use less as PVE itself normally uses very little (I already have plenty shared network storage) and using less total space would make it faster to...
