有人可以提供有关如何将RAID 1与2 HD 1TB同步的完整指南。
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.

非常感谢。
