当它是 md0 sw raid 1 时如何调整 /dev/sda2 的大小

  • 772

4TB我刚刚从2TBssd添加了更大的md0RAID，但大小仍然相同。我试图调整 .partition 的大小，但它说它很忙。Parted 仍在按旧尺寸调整它的大小。

大批：

Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] 
md0 : active raid1 sdb2[3] sda2[2]
      1875210240 blocks super 1.2 [2/2] [UU]
      bitmap: 3/14 pages [12KB], 65536KB chunk

知道我做错了什么吗？谢谢

    解决了这个问题，我放错了大小我没有意识到3.5TB的大小实际上是3840GB而不是3500GB。

    感谢@archemar 的评论，修复了这个问题。
