Workaround:

Creates a new temporary swapfile or an idle partition with a size of 2790-1498=1292m, which is set to swap space when needed.

Steps:

1. View the current disk size

[Email protected] ~]# DF-LH

Filesystem Size used Avail use% mounted on

/dev/sda2 14G 11G 2.4G 81%/

Tmpfs 932M 300K 932M 1%/DEV/SHM

/DEV/SDA1 190M 39M 142M 22%/boot

/dev/sda3 4.7G 25M 4.5G 1%/Home

If the home/home space is found to be sufficient, the directory To build a swap partition folder

2. Create a Swap partition folder

[Email protected] ~]# MKDIR/HOME/SWAPSPC

3. Create temporary files

Create a temporary file of at least 1292M under the Swap partition folder, which is 1292*1024=1323008k.

Create File command: DD command. copies the specified input file into the specified output file, and can be formatted for conversion during the copy process.

If: Read the source free space (why zero, can see http://blog.csdn.net/wangliang888888/article/details/53170731)

Of: The path and name of the output interchange file

BS: block size, unit byte, typically 1kb

Count: Total space Size (total number of blocks), in kilobytes

[[email protected] ~]# dd If=/dev/zero of=/home/swapspc/swapfile bs=1024 count=1350000

4. Set the file to swap space

[Email protected] ~]# Mkswap/home/swapspc/swapfile

Mkswap:/home/swapspc/swapfile:warning:don ' t erase bootbits sectors

On whole disk. Use-f to force.

Setting up Swapspace version 1, size = 1349996 KiB

No label, uuid=0012d538-c2ca-4b58-9442-2dc8cf3e852a

5. Enable Swap space

[Email protected] ~]# Swapon/home/swapspc/swapfile

6. View disk space and swap space again

[Email protected] ~]# DF-LH

You can turn off swap space with the Swapoff command if you do not use swap space

Summary of the commands involved:

Free: View memory status

DF: View disk space usage

DD: Read output data

Mkswap: Setting Swap space

Swapon: Enable swap space

Swapoff: Turn off swap space
