我正在努力手动配置磁盘阵列1+RAID10。我正在 OSX 11.10.3 上的 VM (VirtualBox 5.0.14 r105127) 上尝试该过程。
我采取的策略是：
我执行的完整命令集可用这里。
- 首先安装
centos在第一个磁盘上/dev/sda。 - 然后将所有文件迁移到raid阵列
cp -a mnt/old* mnt/new（甚至包括/boot/efi分区） - chroot 进入 RAID 系统
/etc/fstab使用正确的映射进行编辑- 编辑
/etc/default/grub添加rd.auto=1 rd.lvm=[...] rd.md.uuid=[...]正确的值。 - 重建
initramfsdracut --mdadmconfig --fstab --add "mdraid" --add-drivers "raid1 raid10" - 重建
grub.cfggrub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg - 将新条目添加到 EFI NVRAM 中
for i in b c d; do efibootmgr --create --disk /dev/sd$i --label "CentOS Backup - /dev/sd$i" --load "\\EFI\\centos\\grub.efi"; done - 得到启动失败对于所有条目。
我在这里缺少什么？

答案1
如果我给你我的 {Centos,alma,Rock,Oracle}linux8 实时软件突袭安装的收据会有帮助吗
步骤1）从ISO安装Almalinux
安装在磁盘 /dev/sda 上
步骤2）升级到最新的软件包
dnf upgrade
dnf install vim
（以避免 vi 出现问题）
步骤 3) 安装 Raid 软件包
dnf install mdadm
步骤 4）现在我们需要将分区表从 sda 复制到 sdb
sgdisk -R /dev/sdb /dev/sda
sgdisk -G /dev/sdb
步骤 5) 将 /dev/sdb 上的分区转换为 RAID 磁盘
sgdisk -t 1:fd00 -t 2:fd00 -t 3:fd00 /dev/sdb
步骤 6) 初始化 RAID
mdadm --create /dev/md0 --level=1 --raid-disks=2 missing /dev/sdb1 --metadata=0.90
mdadm --create /dev/md1 --level=1 --raid-disks=2 missing /dev/sdb2 --metadata=0.90
mdadm --create /dev/md2 --level=1 --raid-disks=2 missing /dev/sdb3
步骤 7) 将 /boot 复制到 /dev/md0
mkfs.vfat /dev/md0
mkfs.xfs /dev/md1
mkdir /mnt/md1
mount /dev/md1 /mnt/md1
mkdir /mnt/md1/efi
mount /dev/md0 /mnt/md1/efi
rsync -av /boot/. /mnt/md1
现在我们需要编辑 /etc/fstab 文件。在包含 UUID 的行中
前任。 UUID=c8ac59b8-ce54-4fca-8107-1b04aaa0194d /boot ext3 defaults 0 1 我们用 /dev/md1 替换 UUID 部分或设置正确的 UUID （使用 blkid）
/dev/md1 /boot xfs defaults 0 1
/dev/md0 /boot/efi vfat umask=0077,shortname=winnt 0 2
echo raid1 >> /etc/modules-load.d/raid.conf
cat /etc/modules-load.d/raid.conf
raid1
dnf reinstal kernel-<current>
dracut -f
步骤8）重新启动系统
shutdown -r now
重启后我们可以查看命令的结果：
mount | grep boot
它必须显示类似于此的一行：
/dev/md0 on /boot type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
现在我们可以告诉 GRUB 我们需要 /dev/md0 的 root 权限
echo 'GRUB_PRELOAD_MODULES="raid dmraid"' >> /etc/default/grub
现在编辑/etc/default/grub在 GRUB_CMDLINE_LINUX 中添加 rd.md.uuid= 并从“mdadm --detail /dev/md2”获取 /dev/md2 的 UUID
GRUB_CMDLINE_LINUX="resume=/dev/mapper/almalinux-swap rd.lvm.lv=almalinux/root rd.md.uuid=58fd9cb6:0904f51a:1d561e2a:47682614 rd.lvm.lv=almalinux/swap"
cd /etc;grub2-mkconfig -o $(readlink /etc/grub2-efi.cfg)
dnf reinstal kernel-<current>
dracut -f
步骤 9) 将 /dev/sdaX 添加到 raid /dev/mdY
sgdisk -t 2:fd00 /dev/sda
mdadm --add /dev/md0 /dev/sda1
mdadm --add /dev/md1 /dev/sda2
步骤 10) 将 LVM 移至 /dev/md3
安装在 /dev/sda3 上创建了一个 LVM，因此我们需要将其移动到 /dev/md2 上，然后将其从 /dev/sda3 中删除
pvcreate /dev/md2
vgextend almalinux /dev/md2
swapoff -a
lvremove /dev/almalinux/swap
pvmove /dev/sda3 /dev/md2
pvmove 步骤将需要一些时间，具体取决于 CPU 和磁盘大小，我花了几个小时
vgreduce almalinux /dev/sda3
pvremove /dev/sda3
lvcreate -l +100%VG -n swap almalinux
mkswap /dev/almalinux/swap
步骤 11) 将 /dev/sda2 添加到 raid
sgdisk -t 3:fd00 /dev/sda
mdadm --add /dev/md2 /dev/sda3
现在，执行命令
cat /proc/mdstat
我们可以看到 RAID 正在执行磁盘同步。
完成后重新启动。
