7.6. 为多磁盘集群定义根磁盘

流程

1. 验证每个节点的硬件内省的磁盘信息。以下命令显示节点的磁盘信息：

   (undercloud)$ openstack baremetal introspection data save 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0 | jq ".inventory.disks"

   例如，一个节点的数据可能会显示 3 个磁盘：

   [
     {
       "size": 299439751168,
       "rotational": true,
       "vendor": "DELL",
       "name": "/dev/sda",
       "wwn_vendor_extension": "0x1ea4dcc412a9632b",
       "wwn_with_extension": "0x61866da04f3807001ea4dcc412a9632b",
       "model": "PERC H330 Mini",
       "wwn": "0x61866da04f380700",
       "serial": "61866da04f3807001ea4dcc412a9632b"
     }
     {
       "size": 299439751168,
       "rotational": true,
       "vendor": "DELL",
       "name": "/dev/sdb",
       "wwn_vendor_extension": "0x1ea4e13c12e36ad6",
       "wwn_with_extension": "0x61866da04f380d001ea4e13c12e36ad6",
       "model": "PERC H330 Mini",
       "wwn": "0x61866da04f380d00",
       "serial": "61866da04f380d001ea4e13c12e36ad6"
     }
     {
       "size": 299439751168,
       "rotational": true,
       "vendor": "DELL",
       "name": "/dev/sdc",
       "wwn_vendor_extension": "0x1ea4e31e121cfb45",
       "wwn_with_extension": "0x61866da04f37fc001ea4e31e121cfb45",
       "model": "PERC H330 Mini",
       "wwn": "0x61866da04f37fc00",
       "serial": "61866da04f37fc001ea4e31e121cfb45"
     }
   ]

2. 在 undercloud 上，为节点设置根磁盘。包括用于定义根磁盘的最合适的硬件属性值。

   (undercloud)$ openstack baremetal node set --property root_device='{"serial":"<serial_number>"}' <node-uuid>

   例如：要将根设备设定为磁盘 2，其序列号为 61866da04f380d001ea4e13c12e36ad6，输入以下命令：

   (undercloud)$ openstack baremetal node set --property root_device='{"serial": "61866da04f380d001ea4e13c12e36ad6"}' 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0

   注意

   将每个节点的 BIOS 配置为从您选择的根磁盘引导。将引导顺序配置为首先从网络引导，然后从根磁盘引导。
