raid 1

Hello everyone! I'm experiencing high IO delays (18% - 30% and sometimes higher) when I start a Windows 11 Pro VM on Proxmox VE 7.4-13. I suspect it might be caused by running everything on a ZFS RAID 1 storage but then again I do not experience high IO delays when I run a Linux VM...it's only...

I have a small test system that was using cheap SSDs (just 2 disks mirror, ZRAID-1), and both disks failed in a short time period. I had access to it after the event I am describing below, someone else proceeded to replace disks, etc. as follows : When the first disk failed it was replaced and...

Hello team! I have an HP server, we installed proxmox on 2 1tb disks that have a RAID1 created in the server bios. Eventually, we put in one more disk to have more virtual machines. But this disk was connected without doing Raid or anything and everything worked. But yesterday, they added 2 new...

Hello everyone, I'm fairly new to this server, virtualization and backup stuff. I have a 2 TB hard drive with very important information for me. I am planning to buy two 8TB disks and put them in RAID1. My question is if I can use the Proxmox interface to put them in RAID1 with ZFS and then...

I'm using Proxmox on a Intel Nuc using ZFS. It has a single disk (a fast NVME) and an external disk attached (a slow HDD which I could replace with a fastest NVME). I'm using Proxmox Backup Server virtualized on a VM which backups some local and remote VMs and CTs. Other than that, on the same...

hi everyone, I'm new here. I have proxmox installed on a fujitsu i5, 8Gb RAM, 257Gb SSD. And I have a zyxel NAS with two HDDs each of them has 3Tb (configured as RAID1). I want to move my two HDDs to my fujitsu and configure them over ZFS. Today I tried to copy (backup) all my data from my...

I just set up a new Proxmox server, which will be more of a remote backup server. It has 4x 1TB drives in a ZFS raid 1 array. I expected around 2TB of storage from this, not 1TB. Do I have a misconfiguration, or am I wrong? zpool status: pool: rpool state: ONLINE config: NAME...

Guten Tag, Ich habe, nachdem ich ein Backup wiederhergestellt hatte. Das Problem, dass mein CT Volumen nicht erkannt wurde. Da es auf der HDD war, aber er die als SSD angezeigt hatte. Somit habe ich vermeidliche SSD Volumen ausgehängt und gelöscht und dann die HDD Volumen angehängt. Nur bemerkte...

Hello, I have 1 SSD 256GB, 2 HDDs each with 1TB. I did a software RAID 1 using only the HDD through proxmox environment. It is ZFS filesystem. Imported a vm (4GB RAM). It uses 12GB of RAM. I wanted to host three websites and considering each has 4GB RAM it looks like the RAM will be used...

Hello forum, I have this situation. I have 1 nvme where proxmox is installed, 2 HDD each 1TB. I have already configured two HDD as RAID 1 from the BIOS. PC is model dell 3660 Tower. My question is, how do I make proxmox to recognize those two HDD? And second, can I install VM strictly on the...

Dear, Currently we have some troubles with High IO delay on almost any 'heavy' write on the VM. Our Proxmox is currently installed on Crucial MX500 with ZFS RAID 1. I was searching on the web and I saw that this could happen because of these disks can't handle much IOPS for VM Hosting. I was...

Hi there. I got a problem with a node on my cluster. Here is the conf: Proxmox 7.1 . I tries to remove a lvm-thin provisionning via Datacenter Webui interface. I rebooted one of the nodes where the lvm thin is and i got a read-only filesystem. the system is installed like this ...

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" root@pr-001:~#...

Hi All, 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? Thanks)

TL;DR ZFS RAID1 vs RAIDZ-1? Hello comrades, After a long trip with Proxmox 6 its time to move on to 7 now. Trying a new clean install i found the BTRFS implementation (not interested for now) and an old intrigue that I could never answer. -Why on the Filesystem options i get options like ZFS...

Hi I am running into a weird issue while trying to install PVE 7. I have a Dell R520 with and HBA (H330, IT Mode) and 2 Samsung SSD (consumer grade) connected to it. The system was set to BIOS boot mode and I was able to install Proxmox with ZFS RaidZ1 on those two SSDs, everything worked so...

Introduction The operating system of our servers is always running on a RAID-1 (either hardware or software RAID) for redundancy reasons. Since Proxmox VE 7 does not offer out-of-the-box support for mdraid (there is support for ZFS RAID-1, though), I had to come up with a solution to migrate...

I have a server I've installed Proxmox onto that has one SSD for the main system installation. I'd like to add an identical drive in a month to mirror my base install as a software RAID-1 (raidz maybe?) so I don't have any down time for when the primary SSD fails. Can this be done, and if so, how?

Hi, I'm trying to understand the following situation: We created this setup of disks in our Dell R710 Server: VD 0 = only one SSD 1TB VD 1 = RAID 10 (4 x SAS 600GB) VD 2 = RAID 1 (2 x SAS 600GB) # When I check proxmox about Disk details it shows me 7 disks instead of 3 virtual disks made...

Everything is working fine on 6.3.3 version, I hit upgrade, and reboot. I have two raid arrays: 500 + 500 NVME = raid 1 software 4tb + 4tb = raid 1 software md5 which held 2 x 4tb in it has completely vainshed and the seperate disks are ready to initialize! my md5 array was mounted on...
