lvm

Hi! I have run dual-primary drbd successfully with two node proxmox cluster, each pve node being also drbd node (and using local storage). And /dev/drbd0 block device is used as lvm pv device, lvm needs to be initialized at one node since block device content appears or rahter is same and both...

I have some filesystem questions regarding PVE, ZFS and how they interact with VMs. The storage system I'm trying to achieve consists of 5 physical disks: Physical Disk Purpose RAID Disk 1 + Disk 2 PVE + mirror ZFS mirror Disk 3 + Disk 4 VMs and container storage a mix of striping and...

I have inherited a LSI SAS9200-8e 6Gb/s SAS PCIe x8 HBA in a Dell R710 server connected to a EMC KTN-STL3 JBOD with 15 1TB drives. I don't see the drives in Proxmox or in the Debian console. Can someone point me to a guide that explains setting up the server BIOS, the HBA's BIOS and/or...

I have built a 6.10 kernel using clang (with .config from generic ubuntu) on Ubuntu 24.04. I am able to run it on Ubuntu but not on Proxmox. On Proxmox, I get following error: Alert! /dev/mapper/pve-root does not exist. Dropping to shell Running lvm pvscan returns nothin, and adding...

I have been following some posts, but those were meant for ZFS. I already changed the configuration file of the VM and set the variable template: 0 Renamed the LVM from base-101-disk-0 to vm-101-disk-0 Now I'm trying to change the attributes from Vri-a-tz-k to Vwi-aotz-- assuming those are the...

I have a 128 GB internal SSD disk on my machine, and have installed a fresh Proxmox with the following setup: 16 GiB for the Proxmox OS root (set using the maxroot parameter during installation) 7.58 GiB allocated to SWAP 32 GiB allocated to VM-100 It seems that the proxmox installer has...

Hello! I reset my proxmox nodes hostname and then joined a cluster and now the dropdown for my node only shows local when it had previously shown several other disks/volumes. In disks/directory I see the directories of the drives and where their path is mounted and I can access all the data on...

Hi everyone, Proxmox newbie here. I got a few questions regarding vm disk management. Context: The main usage for my PVE, in a home environment, is mainly to host a file server and a multimedia server (DNLA-like), plus a few other small VMs for testing and playing around. The PVE has the...

Hello, I am fairly new to Proxmox. I've searched Reddit and this forum, and I hope I am not asking an FAQ that's already been answered. I couldn't find anything on the Web. Please bear with me. I have set up Proxmox on a NAS. Due to it only having 8Gb of memory, I chose to go with LVM+ext4 and...

Hi! I found some comments about using Snapshots (LVM or ZFS or GlusterFS ) in Storage causes disk performance degradation ( permanent slow I/O ), but if you remove all the Snapshots, the performance is returning to normal. Has anyone here had a similar experience?

First of all this thread is basically the aftermath of this one. It's not necessary to read it, but it paints a good picture of how this thing behaves. So I have 2 GPUs that I am passing through to 2 VMs (usually one windows and one linux or mac). Everything works fine when I am starting them...

Hi, Background: I ran Proxmox for years on a single node and for some reason which I can't recall, stupid me, renamed the standard logical volume from "data" to something else for the lvm thin pool. It worked all fine... Now I started to adding some more nodes and face the challenge that all...

My DEV Storage ran out of space, I've already extended it on the Storage array. But unsure on how to extend within Proxmox without lossing 6TB of VMs. lsblk on sdb, sde, sdq, sdr pvscan Any direction would be greatly recieved.

I have a Dell R530, I recently switched from using RAID5 disks with the built in raid card to HBA mode and using ZFS. Before when I was using LVM, my sabnzbd could max out my connection (between 120-150mbps), however after switching I'm only hitting between 5-30mbps consistently. sab reports...

Hi guys, since I'm still at the beginning with proxmox (coming from unrai*) I'm wondering about the right disk layout. I have quite a wild growth concerning my hard disk landscape and wanted to ask if a ZFS makes sense or rather LVM? How could a possible ZFS make sense with the disks? I also...

How to work around this error (when trying to make an LVM): > create storage failed: command '/sbin/pvs --separator : --noheadings > --units k --unbuffered --nosuffix --options pv_name,pv_size,vg_name,pv_uuid > /dev/disk/by-id/scsi-36589cfc000000f92915fcd719135fe85' failed: exit > code 5...

Hi All I have a qcow2 image of Redhat VM. My understanding from the storage guide is that only directory backend that supports qcow2 image. My question is if I have imported a qcow2 image on the directory backend, can I instantiate a VM on some other storage type, like LVM ? I want to use...

Hi, I know that there is already "LVM over iSCSI/FC" for shared block storage (SAN) which carves out LV from a shared VG/LUN for individual VM disks - but with no snapshot and thin provisioning support my question is why is there no (extended) storage plugin which provides 1.) "QCOW2 over/on...
