我有一个 1TB 的硬盘/dev/sda
,我买了一个 2TB 的新磁盘/dev/sdb
。里面已经有一些分区了sda
。
我运行dd if=/dev/sda of=/dev/sdb
,然后把我的旧 1TB 磁盘扔进/dev/sda
了垃圾箱。然后我在新磁盘上启动操作系统,一切正常。
然后我想添加一个新的分区到/dev/sdb
。我运行gdisk
但它不允许我这样做。
gdisk 显示的内容如下:(共有 3907029168 个扇区(2TB),但最后一个可用扇区是 1953525134(1TB))

我的磁盘现在是 2TB,但 GPT 分区表仍然认为有 1TB。使用它v
来验证磁盘,它说
Problem: The secondary header's self-pointer indicates that it doesn't reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.

运行x
