# lab-iscsi-target.yaml - iSCSI target reference for shared storage
|
|
#
|
|
# Reference configuration for an iSCSI target serving the IncusOS cluster's
|
|
# lvmcluster shared storage pool. All 3 IncusOS cluster nodes connect as
|
|
# iSCSI initiators via their built-in iSCSI service.
|
|
#
|
|
# Two deployment options (see notes/shared-storage-guide.md):
|
|
#
|
|
# Option A (tested, recommended for lab):
|
|
# Deploy as an Incus container with `tgt` on the existing cluster.
|
|
# No extra VM needed. See shared-storage-guide.md Section 2 for the
|
|
# full tested walkthrough.
|
|
#
|
|
# Option B (this file):
|
|
# Deploy as a standalone Proxmox VM with targetcli-fb. Better for
|
|
# production-like setups or when you want the target independent of
|
|
# the Incus cluster. Manual Proxmox deployment required.
|
|
#
|
|
# Architecture:
|
|
# iscsi-target (410) - Debian 12 + targetcli-fb, 200G LUN
|
|
# oc-node-01 (400) - iSCSI initiator + lvmcluster
|
|
# oc-node-02 (401) - iSCSI initiator + lvmcluster
|
|
# oc-node-03 (402) - iSCSI initiator + lvmcluster
|
|
#
|
|
# Option B deployment steps:
|
|
# 1. Download Debian 12 cloud image or install from ISO
|
|
# 2. Create VM: VMID 410, 1 core, 1 GiB RAM, 200 GiB disk
|
|
# 3. Network: vmbr0, VLAN tag 69
|
|
# 4. Static IP: 192.168.102.150/22, gateway 192.168.100.1
|
|
# 5. After boot: run post-install commands below
|
|
# 6. Enable iSCSI on IncusOS nodes (shared-storage-guide.md Section 4)
|
|
#
|
|
# RAM budget: 1 GiB (adds minimal overhead to the 28 GiB cluster)
|
|
#
|
|
# See notes/shared-storage-guide.md for the full shared storage guide.
|

# Reference configuration (for documentation — not used by incusos-proxmox)
