我有 2 个硬盘，分区相同，并且它们之间有 RAID-1。我想打破镜像（这样没问题），然后从镜像的次要一侧启动无需使用 Live-CD（这很重要）。另外，我没有服务器的物理访问权限。
我尝试使用辅助分区 (/dev/sdb*) 创建新阵列并设置 grub 和 /etc/mdadm.conf，但不起作用。我想我漏掉了一些东西。
Following is my partitioning (for sda, sdb is the same):
Disk /dev/sda: 64.4 GB, 64424509440 bytes
255 heads, 63 sectors/track, 7832 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00029482
Device Boot Start End Blocks Id System
/dev/sda1 1 256 2048000 fd Linux raid autodetect
Partition 1 does not end on cylinder boundary.
/dev/sda2 * 256 287 256000 fd Linux raid autodetect
Partition 2 does not end on cylinder boundary.
