Turn off VMware's Linux system, set the original hard drive capacity, and boot.

#添加新分区, load new capacity on the raw capacity basis

[Email protected] ~]# fdisk/dev/sdawarning:dos-compatible mode is deprecated. It ' s strongly recommended to switch off the mode (command ' C ') and change display units to sectors (Comman d ' u '). Command (M for help):

Enter N, carriage return. Add a partition

Command (M for help): Ncommand action E Extended P primary partition (1-4)

Enter P, enter select Primary partition

Input 4, enter select Partition 4, because the above query to Sda1,sda2,sda3 has been used

Enter 8e, enter change to LVM

Enter W, return to save settings, and restart your computer

Format the new partition just after booting
