4， 点击扩展，等到扩展完成。

5, 开启linux主机，使用fdisk和resize2fs命令

root@test:~# fdisk /dev/sda

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

GPT PMBR size mismatch (46555135 != 85983231) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
