I upgraded the test server from pve7 to pve8 - I found the following annoying bug:
> I issue the server shutdown - ( init 6 ), but the shutdown process is hanging and looping the following message:
"sytemd-shutdown - Failed to get MD_LEVEL property for /dev/mdX, ignoring: No such file or...
I assembled mdadm raid0 from two Samsung 970 Evo plus NVMe SSDs, created an LVM VG on it and gave the thick LV as a virtual machine disk based on Centos8.
On a hypervisor, this RAID delivers about 7GB/s read performance.
When I test inside the guest OS with:
fio --readonly --name=onessd...
Good day everybody,
we would like to subsequently set up a software raid 1 on our Proxmox system with mdadm.
Proxmox itself is currently installed on an NVMe with ext4, which is now to be mirrored on another NVMe.
However, the following error occurs.
"Floating point exception"
I have a trouble where mdadm autoactivates zfs volumes from VM's. I would not like mdadm to touch anything from zfs volumes.
I tried to search for it since it's more like debian problem, but could not filnd a solution. Probably a filter when loading mdadm module?

I have 2 NVMe M.2 drive 256 Gb in my server and would like to use them as mirror for OS with PVE.
But as I see PVE installation offers RAID on ZFS only.
What is the best way to install PVE on mdadm RAID1?
Hey guys, I just updated the BIOS and Proxmox to the latest version for each, and wanted to tackle one more issue. I've been hosting a couple network drives on my Proxmox host, basically just a network directory for music and one for torrents. I play music SOMETIMES from this directory, but...
I would like to know if it's possible to assign more than one phisycal SSD to VM (Debian in my case) with /dev/disk/by-id/ command.
I want to passthrough two SSD disk and create a mdadm Raid 1 beetween them to increase read performance and reliability of VM's data (xfs partition on SSD...
ich habe mit mdadm herumgespielt und es klappt erstmal alles. Wenn ich aber ein Reboot des kompletten Server mache kommt das Raid1 nicht wieder. Auch ein erzwungenes Reassemble löst das Problem nicht. Erst ein erneutes Erstellen des Raids stellt den gewünschten Zustand wieder her...
ich habe folgendes Problem. Wir haben ein "Budget" Node mit 3x Samsung 860 QVO 1TB. Eine Disk wird für das System an sich verwendet und ein Software RAID 1 für den VM Storage.
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
ich heiße Marcel und bin gerade dabei Proxmox auf meinem Server zu installieren. Soweit funktioniert alles. Nur ein Openmediavault will nicht so wie ich das will.
Ich habe 5 Festplatten die ein Raid 5 bilden sollen. Noch dazu ein Raid 0 mit 3 Festplatten. Wie ich schon herausgefunden...
I am setting up a RAID on a new Proxmox 6.1 server and I wanted to update the kernel in order to keep the RAID after a reboot (I had to do that with Proxmox 5.x)
To begin, I created the RAID :
mdadm --create /dev/md3 --metadata=0.90 --level=1 --assume-clean --raid-devices=2...
I have Proxmox installed on top of Debian software RAID-10.
Today it froze and I restarted manually, unfortunately it doesn't boot due to mdadm error.
A. It gives following error on boot.
B. cat /proc/mdstat
What I find weird is boot error UUID doesn't...
Hope you are fine. I am working on a research project about software RAID. I scrutiny great software, Proxmox , as a case study in this research. I just wanted to ask you which method you have used for implementing software RAID. I have acquaintance with Linux kernel md, did you use this...
After fighting with ZFS memory hunger, poor performance, and random reboots, I just have replaced it with mdraid (raid1), ext4, and simple qcow2 images for the VMs, stored in the ext4 file system. This setup should be the least efficient because of the multiple layers of abstraction (md and...
I'm struggling with choosing the best configuration for my setup.
I'm using `pve-manager/5.3-5/97ae681d (running kernel: 4.15.17-1-pve)`
I have a OpenMediaVault in a virtual machine and I want to have my 2x3TB disks in a raid1/mirror and have OMV use the whole for a CIFS share.
I've been using Linux on various PCs as a home server over the years, and now when it's time to retire the old PC and replace it with a somewhat newer, I decided to use proxmox.
The old Linux PC had two physical disks in a RAID 1 configuration (mdadm) that I've put in the new server running...
Proxmox 4.4 / prox instal on 2x32go SSD in raid 1 + 3x 4to in raid 5
After a bad crash I would like to re-construct my server data :
I have a raid 5 made with mdmda I have enabled mdmda found in the lvm.conf.
After I built my raid 5 (3x 4to) I could see it / make my pv / my vg and all...
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...
