磁盘：
/dev/sda
/dev/sdb
/dev/md127

此配置将在两个单独的磁盘之间设置RAID0 ext4卷数据。
问：如何为3个磁盘配置raid10？
{
"ignition": { "version": "2.0.0" },
"storage": {
"disks": [
{
"device": "/dev/sda",
"wipeTable": true,
"partitions": [{
"label": "raid.1.1",
"number": 1,

}]
},
{

}
],
"raid": [{

"/dev/disk/by-partlabel/raid.1.1",
"/dev/disk/by-partlabel/raid.1.2"
],
"level": "stripe",
"name": "data"
}],
"filesystems": [{
"mount": {
"device": "/dev/md/data",
"format": "ext4",
"create": { "options": [ "-L", "DATA" ] }
}
}]
},
"systemd": {
"units": [{
"name": "var-lib-data.mount",

"contents": "[Mount]\nWhat=/dev/md/data\nWhere=/var/lib/data\nType=ext4\n\n[Install]\nWantedBy=local-fs.target"
}]
}
}
我尝试使用下面的conf。操作系统已成功安装，但在首次启动时，它会在“启动作业正在运行以进行点火（磁盘）”中暂停
{
"ignition": { "version": "2.0.0" },
"storage": {
"disks": [
{
"device": "/dev/sda",
"wipeTable": true,
"partitions": [{
"label": "raid.1.1",
"number": 1,
"start": 0
}]
},
{
"device": "/dev/sdb",
"wipeTable": true,
"partitions": [{
"label": "raid.1.2",
"number": 1,
"start": 0
}]
},
{
"device": "/dev/md127",
"wipeTable": true,
"partitions": [{
"label": "raid.1.3",
"number": 1,
"start": 0
}]
}
],
"raid": [{
"devices": [
"/dev/disk/by-partlabel/raid.1.1",
"/dev/disk/by-partlabel/raid.1.2",
"/dev/disk/by-partlabel/raid.1.3"
],
"level": "raid10",
"name": "data"
}],
"filesystems": [{
"mount": {
"device": "/dev/md/data",
"format": "ext4",
"create": { "options": [ "-L", "DATA" ] }
}
}]
},
"systemd": {
"units": [{
"name": "var-lib-data.mount",
"enable": true,
"contents": "[Mount]\nWhat=/dev/md/data\nWhere=/var/lib/data\nType=ext4\n\n[Install]\nWantedBy=local-fs.target"
}]
}
}
P.S：我正在使用PXEBOOT安装coreos
coreos-install -V current -C beta -c cloud-config.yml -i ignition.yml
欢迎来到SuperUser。你向我们展示你的尝试是件好事。你有什么关于RAID的文章？ RAID 10至少需要四个磁盘，因为它的RAID 0高于RAID 1.您可能需要设置RAID 01，它是RAID 0以上的RAID 1。

谢谢。 :)维基百科， en.wikipedia.org/wiki/Non-standard_RAID_levels ，说raid10有3个磁盘是可能的。

此外，2个磁盘的raid0配置也会在同一错误上暂停。

如果一般情况下可行，这是无关紧要的。您的整个工具链必须支持您的非标准配置（为什么不使用标准配置？）。但是我可以看到我让你走上正轨，因为你试图将其排除在问题的根本原因之外。

乐施会。根据你的说法，哪种配置最适合3盘。
