1. Multipath config¶

⚠️Configuration with each node

1.0 Prepar SAN storage¶

Create VV (Virtual Volume) in SAN storage
Allocate VV (Virtual Volume) to all node

1.1 Multipath installation¶

apt install -y multipath-tools

1.2 Config multipath¶

Create multipath configuration file

mkdir /etc/multipath/conf.d

Start multipath service

systemctl enable multipathd.service --now
multipath -ll

2. Config SAN storage¶

2.1 Create VG¶

⚠️Any an node operation

Create PV

pvcreate /dev/mapper/mpatha

Create VG

vgcreate pve-san /dev/mapper/mpatha

Check VG

vgdisplay

3. Cluster storage config¶

3.1 Create storage¶

Login cluster node, and click Storage->Add->LVM

Input LVM info

If you need VM Snapshots, please checked Allow Snapshots as Volume-Chain

Confirm storage status
