lvm

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...

Hello friends, I am very new to proxmox so i need some help to proceed, thanks in advance. i have 1 hpe 1060 storage and 2 hpe dl380 server the storage is directly connected to the server1 through fiber channel with two paths and same way server2 is connected to the same stroage what i wish...

I have 1 R530 server with a 17TB virtual disk, plus a Dell md3200i with a single 35TB disk. Both disks are in proxmox and I can add them to the VM, however I'm trying to combine them as one big disk. I was looking into mergerfs to do this (VM is running Ubuntu), however I thought it might make...

Heya, I'm having a bit of a weird issue. After rebooting my Proxmox node today the 4TB HDD constantly seems to go into "failure" despite physically being okay, Proxmox always reports that "tmeta" and "tdata" is active so it can't activate the LV. Activation of logical volume...

Hello, I am quite new to Proxmox. But last night, due to an electric blackout, my single node proxmox, with a single ssd, shuts down. At the power on the node won't boot, after few seconds the only thing I see via console is: pnp 00:01: can't evaluate _CRS: 12311 Found volume group "pve" using...

Updated-edit on bottom Hey I'm pretty new to proxmox (and zfs) been using it for about a month or two and really like it so just wanted to say thank you right away. However there are a couple things I don't fully understand, I think it will be clear after I explain what I'm trying to do and...

Finally got all the parts for my home server and currently testing. I plan to have SR-IOV passthrough for VM networking, HBA passthrough for storage VM. This means i can't take live snapshots and because it's just one node i don't need replication. Without using 2 major benefits of ZFS, should...

Hello, Ran into a problem with my Proxmox VE. My LXC container, which is my go-to NAS, just won’t boot up after a reboot. Here’s the error it’s throwing at me: run_buffer: 322 Script exited with status 32 lxc_init: 844 Failed to run lxc.hook.pre-start for container "100" __lxc_start: 2027...

Hello all, I have a small ITX host with only one SSD in it, for proxmox installation and the VM storage. But I don't understand how my local-lvm is almost full while it should have plenty space left. Here is the physical disk : If I understand correctly, Proxmox create a "root" LV of...

I recently had an SSD fail on writes, and luckily, I could clone it using dd without much issue. Had to run fsck /dev/mapper/pve-root, and all was good. However, the new drive is 500GB; the previous was 120GB. I'm trying to claim that space and not quite following the instructions in another...

After a restart of my server I get the following error: TASK ERROR: activating LV 'pve/data' failed: Check of pool pve/data failed (status:1). Manual repair required! I tried lvconvert --repair pve/data and got this output: truncating metadata device to 4161600 4k blocks Child 3798 exited...

I wanted to show the steps that I took to accomplish this task. I am a real beginner to Proxmox, and I struggled with the idea of changing the disk partitions using a live disk and GParted, etc. So, I looked for an easier method for me to do this, and I hope this helps someone. I had...
