Hey evreryone! I was able to get guidance on getting my SAS disks to show up in Proxmox. I have two Dell R350s and a Dell EMC ME4012. Each R350 has two SAS cables connecting to controller A and B. When I look at the disks I see..
So the ME4 3.84 TB and 1.20TB disks show up twice. Same way...
I'm new to Proxmox and I'm setting up a demo cluster to figure everything out before building a production system. I'm trying to get iSCSI multipath working following the instructions here. Here's the contents of my storage.cfg file
We have a cluster of 7 nodes. VMs and LXCs are stored on external storage, on a shared LVM, via iSCSI.
We recently had to move from a 2 x 1Gbps iSCSI multipath connection to a 1 x 10 Gbps FO ethernet (single link iSCSI connection, no multiphating).
The iSCSI storage has 4 ethernet ports...
I have configured multipath on 4 nodes in my Intel Modular Server. The problem is that when I stress test one of the storage control module while the system is running, I get different results each time.
Some times, multipath is working and the path is switch automatically, but some times...
Since I setup some iscsi storage in Proxmox Version 6, I have a lot of error in my server logs.
In dmesg or /var/log/messages or /var/log/kern.log, I have a lot of:

We're running ProxMox 7.1-5 on Dell R7525 servers (AMD cpu) with (2) Dell Broadcom 57414 Dual Port 25GbE SFP+ nic cards attached.
We've got (2) 25GbE switches cabled correctly and connected to our ISCSI storage appliance.
One card is in Riser 1 and the other is in Riser 3; I'll...
This is the same error that I posted here. However, the resolutions in that thread are not working. I've narrowed down the problem as a multipath issue, but I'm creating a new thread because this situation seems to be unique.
Node A and B were clustered and are running v6.4-13 and are identical...
I upgraded from version 6.4 to 7.0 of one of the blades on my Intel Modular Server
After reboot multipath not show any device:

on another node with proxmox 6.4 I have:

Hi, I am trying to configure multipath with a DELL SC5020 iscsi storage. I followed the official Proxmox guide but can't get it to work. I think the problem is in the configuration of the multipath.conf file.
I am using Proxmox 6.4
I've been testing various configurations of the multipath.conf...
I'm struggling with multipath and lvm configuration. I know it is not directly related to PBS, but on this there runs PBS 1.0.11 (Enterprise subscription).
I want to use a SAN LUN (Multipath with 2 links) as a physical volume, to run LVM on that and use it as a Datastore for PBS.
I'm running a PVE 5.2 cluster with 4 nodes. The cluster is attached to a SAN, an HP P2000 G3 iSCSI. VMs are hosted on the SAN.
The first controller of the SAN failed. Everything is running on the second controller, but I can't manage PVE anymore.
Although VMs are running, it seems that...
I have install and configure 3 Nodes Cluster Proxmox Virtual Environment 6.3-3 with multipath-tools Installed: 0.7.9-3+deb10u1 and seeing following errors continuously.

I had a Promox 5 cluster with 3 SAN storage bays. When i tried an upgrade to pve 6, one of the bays was no longer visible under multipath :-(
So to take no risk on my existing infrastructure, I decided to create a new proxmox 6 cluster from scratch. (iso 6.2-1)
I installed 3...
I have exported an iSCSI LUN with multipath to a PBS server in the SAN.
How should I initialize this remote disk? It doesn't show up in drive list.
[1:0:0:0] cd/dvd QEMU QEMU DVD-ROM 2.5+ /dev/sr0
[2:0:0:0] disk QEMU QEMU HARDDISK 2.5+ /dev/sda
I "think" I have this configured correctly but wanted to see if there was others that might know better.
Step 1. in GUI add a new iscsi pointing to the iscsi portal and adding 1 target. (also uncheck Use LUNs)
Step 2. Add node-startup = automatic to /etc/iscsi/iscsid.conf (Restart iscsi...
I would like to ask for help with configuration of multipath on iSCSI disk in Proxmox 6.2.
I have configured multipath on the server:

We are trying to deploy an HA storage environment on Proxmox using multipath, a Synology NAS (RS1619xs+) and an iSCSI SAN, and we cannot get the multipath driver to manage the iSCSI LUNs. We need a little help to go further or to interpret the errors we are commiting.
This is what we are...
I've been following instructions from this wiki page: https://pve.proxmox.com/wiki/ISCSI_Multipath
I get to the point where I run apt-get install multipath-tools and I get this output:

I have 4 Proxmox servers, all connected to a Fiber Channel storage using multipath which is serving two volumes: STORAGE-DATA and STORAGE-DUMP.
Every node is showing 4 sd* devices (2 per volume) and one mapper device per volume:

Proxmox version 6.1-7. Trying to get LVM over iSCSI working. My iSCSI server is running OmniOS using NappIt. I created the iSCSI share on the NappIt server and created my host target group and iSCSI target group and view. Proxmox cluster (six nodes) can add the iSCSI volume with no issues...
