前回構築したクラスタでは、オンボードのNICを指定していました。

USB NICを増設してそれをDRBD同期とします。

Proxmox上でLinux Bridgeを作成、IPアドレスのアサインまで済んだ状態とします。

コントローラを実行しているノードで以下を実行して、インタフェイスの追加と優先を変更します。

# linstor node interface create pve-alice SAN_1G 192.168.3.21
# linstor node interface create pve-belle SAN_1G 192.168.3.22
# linstor node interface create pve-clare SAN_1G 192.168.3.23

# linstor node set-property pve-alice PrefNic SAN_1G
# linstor node set-property pve-belle PrefNic SAN_1G
# linstor node set-property pve-clare PrefNic SAN_1G

追加したカードは以下で確認できます。クラスタ作成時はdefaultが勝手に作られます。

# linstor node interface list pve-alice

ついでにディスクをIntel SSDPEKKF256G8Lに変更してみます。

Wifi接続用のKEY A/EからKEY Bに変換するアダプタで増設します。これでT630にnvmeのSSDを搭載できるようになりますが、pcie gen1 x1になるので2.5Gbpsの通信速度になるので、SATAポートより遅いです。

その状態でベンチマークしてみます。シーケンシャルリードは275MiB/s、ライトは82MiB/sでなかなかです。
