Hello all. I am aware the issue of configuring LVM-Thin in a clustered environment with shared storage has been extensively discussed and why it is a really bad idea. However, l would like to ask this question from a different angle. When looking into our SAN storage configuration, there is an...

Coming from the VMware world, and deploying Proxmox 9.1.1 for the first time. Looking for the correct NAS setup to support the following shared iSCSI attached storage across all nodes Deploy Thin disk VMs perform snapshots live migrations / move disk (vmotion / storage vmotion) HA In VMware I...

I have two hosts with Proxmox installed. I connected each server with two 10 Gbit iSCSI links to a Fujitsu ETERNUS storage system. On the storage, RAID 5 is configured with a single volume. I have set up a multipath connection and I am currently using LVM. Is LVM the only option? I tried...

I started a thread on the Proxmox reddit which quickly went down a rabbit hole and finally hit the bottom. https://www.reddit.com/r/Proxmox/comments/1sf3l9y/high_io_pressure_stall_during_os_install_iscsi/ TL;DR I am experiencing high IO pressure stalls peaking at 30% along with extremely long...

Environment: proxmox-ve: 9.1.5 pve-manager: 9.1.5 lxc-pve: (latest as of 2026-03-14) Storage: iSCSI LUN from NetGear NAS with LVM on top (vm-iscsi-lvm) Problem: When creating a new LXC container directly on an iSCSI-LVM storage, the container fails to start with the following error: ---------...

Hello all, Challenge is to connect PVE to a Dell Compellent and it is not presenting like any iSCSI I have seen recently. Unfortunately, all of its host ports are on the same broadcast domain, so I will also have to contend with that. Notice how all of the targets have the same IP (which is...

I thought this may useful to people that are having multipathd and udev-worker deadlocking issues. My Environment - Proxmox 9.1.1 - Purestorage ISCSI server Purestorage requires device queue limits, and scheduling attributes to be changed via udev...

Hello Everyone, i have a PBS server (version 4.1) running as a VM in a PVE (8.4) with a synology ISCSI connected (have installed open-iscisi in PBS via debian repo) as a datastore. The issue i am facing is that, after a few minutes PVE reports the following error pbs: error fetching...

BACKGROUND: I have a Windows 11 VM that runs my cameras VMS (Video Management Software). My server is in a cluster with 3 other identical machines running other production VMs and they are using their internal NVME SSDs in a CEPH cluster for High Availability. I have a separate server running...

Hello Members I'm trying to set up iSCSI with multipath in a PVE cluster to a SAN. I want to achieve redundancy and load balancing. There are four paths to the SAN. However, multipath only uses two paths and creates only one priority group root@pve2:~# multipath -ll vmstorage1...

Hello all! I'm a developer with OSNEXUS. We’re excited to announce the pre-release version of the QuantaStor Proxmox Storage Plugin, designed to simplify the management of QuantaStor storage within Proxmox VE clusters. This plugin enables seamless creation and management of ZFS-over-iSCSI...

Hello - setting up a Proxmox 9.1 cluster to connect to a Dell PowerStore SAN. I could do iSCSI or FC but would prefer to do FC. I need to maintain the ability to do VM snapshots and would prefer to be able to do Proxmox HA (though not strictly necessary). Can this be accomplished by presenting...

Hello community :) I am experiencing extremely high latency and abnormal read/write performance on my Proxmox nodes as well as on my VMs. It takes several hours to install a VM running Debian 13 (Trixie), and the same issue occurs with Windows. Environment Proxmox VE: 8.4.0 (no-subscription)...

We are conducting a proof of concept using Proxmox VE 9.1, like a lot of people here, to replace VMware ESXi + vCenter. We can't seem to find a definitive answer to our iSCSI networking questions. For our POC we will be using our Nimble Storage array that has redundant controllers connected to...

Hello, I'm a bit confused when it comes to storage options for LXC containers. I want to move all of my disks to Truenas and migrate all disks there. In VM I can easily use ISCSI as backend storage, no issues here. But documentation on LXC containers also states that remote storages like ISCSI...

Hello everyone, This is a brief public service announcement regarding an iSCSI upgrade incompatibility affecting PVE 9.x. A bug introduced in iscsiadm in 2023 prevents the tool from parsing the iSCSI database generated by earlier versions. If you encounter this issue, you will see the message...

I have an iSCSI LUN with LVM storage layered on top. I'm not sure if this is the best configuration, but I enabled fleecing to the same storage and snapshot-as-volume-chain. Fleecing used to work fine before I turned on the volume chain function and converted the .raw disks to .qcow2. Now it...

Hello! I've recently set up a new dedicated server for PBS. When I run backups now the host drops the iscsi connection to the storage. What's really puzzling is that the connection is on a different physical interface and network, and backing up to the previous server (which was a VM running on...

Hi, OK, I have two pve v9.0.11 nodes in my cluster where I'm trying to get iSCSI and multipath working. As part of the overall hardware set up, I've got the two nodes (call them node 1 and 2), a TrueNAS SAN (Enterprise, dual controller), and two Unifi fiber agg switches (not the ECS model so no...
