有人可以提供关于如何同步 RAID 1 与 2 HD 1TB 的完整指南。
情况如下：
# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
md2 : active raid1 sdb2[1]
20478912 blocks [2/1] [_U]
md3 : active raid1 sdb3[1]
1932506048 blocks [2/1] [_U]
bitmap: 15/15 pages [60KB], 65536KB chunk
unused devices: <none>
# fdisk -l
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

我不想单独进行，因为我确定不会删除数据。
非常感谢。
