Virtual machines for Linux under VMware increase disk space

Power off the virtual machine first, do the following: " virtual Machine"--"Virtual machine settings"--"disk"--"extension"

You can optionally add the size of the disk you need to increase to (such as 15Gb, the total amount of disk, including the original disk capacity); Then restart the power supply to enter the system to do the following steps set.

1. Start the virtual machine system, log in as root (all subsequent steps should be logged in as root), and be viewed at the command line with Fdisk-l. Since this is a direct modification of the original space size, you can see that the/DEV/SDA space changes to 16.1GB (the original disk space increased from 10G to 15G). If you add a virtual hard disk from the VMware menu, will there be a/dev/sd?, here? Represents the hard disk number, the first hard disk number is a, SDA, the second is SDB, the third is SDC, and so on, generally speaking, if you have not previously increased the hard disk, The original hard drive is SDA, and the virtual hard disk number added through the VMware menu is SDB. If you add a second hard disk that is an IDE hard disk, you should see the HDB, and if it is a SCSI hard disk, you should see SDB.

2. Use FDISK/DEV/SDA to enter menu items, m is List menu, p is list partition table, n is add partition, W is save and eject. Since there are only 5 g of disks added here, 5G is zoned as a single zone.

[email protected] ~]# FDISK/DEV/SDA

The number of cylinders for this disk was set to 1958.
There is nothing wrong with the, but this is larger than 1024,
And could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from the other OSs
(e.g., DOS fdisk, OS/2 fdisk)

4. Set Boot auto-load

Create mount point: After mkdir/cm mount, modify the Vi/etc/fstab partition table file,

At the end of the file add /dev/sda3/cm ext3 defaults 0 0 then save and restart.

(Note: If the partition table is incorrect, it will result in the Linux desktop system, but then the system will enter the CommandLine mode, we can fix the wrong fstab in commandline mode, However, by default this commandline mode will be the Read-only file system, which means that any modifications you make are not allowed, but you can remove this restriction by command mount/O remount,rw.
