Proxmox iSCSI target with Synology NAS shared storage and troubleshooting

Overview

In this video, we will explore how to attach a Proxmox server to an iSCSI LUN (Logical Unit Number) provisioned on a Synology NAS, enabling shared storage and redundancy benefits. The author, Brandon Lee, will walk us through the step-by-step process of setting up the iSCSI target on the Synology NAS and configuring the iSCSI storage on the Proxmox node. Additionally, he shares troubleshooting tips and methods to overcome common errors encountered during the process.

Section 1: Setting up the iSCSI Target on Synology NAS

To begin, Brandon sets up the iSCSI target on the Synology NAS by:

• Opening the Synology NAS application and navigating to the iSCSI menu option
• Creating a new iSCSI target and specifying the target name and security settings
• Creating a LUN (Logical Unit Number) and assigning it to the iSCSI target
• Configuring advanced settings, including allowing multiple sessions from one or more iSCSI initiators and selecting the network interface for iSCSI traffic

Section 2: Configuring iSCSI Storage on Proxmox Node

Next, Brandon configures the iSCSI storage on the Proxmox node by:

• Adding an additional network adapter to the Proxmox host, ensuring it is on the same layer 2 segment as the Synology NAS
• Verifying network connectivity using the traceroute command
• Configuring the iSCSI connection on the Proxmox node, specifying the target name, portal, and LUN
• Creating an LVM (Logical Volume Manager) on top of the iSCSI connection

Section 3: Troubleshooting iSCSI Connections

Brandon shares common troubleshooting tips and methods to overcome errors, including:

• Verifying networking configuration and connectivity using ping and traceroute commands
• Resolving issues with disk association and volume groups using command-line commands and reboots

Takeaways

• Setting up an iSCSI target on a Synology NAS and configuring iSCSI storage on a Proxmox node can be achieved through a series of steps
• Common troubleshooting tips and methods can help overcome errors and issues encountered during the process
• Using iSCSI shared storage can provide benefits such as redundancy and improved performance in Proxmox environments
