How to Increase swap space in Solaris/Linux

Linux temporarily adds swap space:

Step 1:

# Dd if =/dev/zero of =/home/swap bs = 1024 count = 500000

Note: of =/home/swap: place the swap space. The size of count is the size of the added swap space, and the size of 1024 is the block size. Here it is 1 K, so the total space is bs * count = 500 M

Step 2:

# Mkswap/home/swap

Note: format the space in the previous step into various swap types.

Step 3:

# Swapon/home/swap

Note: Make the created swap space

To close the newly opened swap space, run the following command: # swapoff

Solaris temporarily increases swap space:

Step 1:

# Mkdir/swap

Step 2:

# Mkfile 51200 k/swap/s01

Note: Create an empty file of the required size

Step 3:

# Swap-a/swap/s01

Note: parameter a indicates creating a swap partition.

Step 4:

# Swap-l

Note: Verify that the swap file is correctly added to the disk space pool.

Step 5:

# Swap-s

Note: Summary of swap space

In addition:

If you want to use the entire partition as the swap space, you can use the block device name as the parameter of the swap command:

# Swap-a/dev/dsk/c1t1d2s1

To make sure that the partition is added as swap at startup, add the following content to the/etc/vfstab file:

# Deveice device mount FS fsck mount

# To mount to fsck point type pass a tboot ops

/Dev/dsk/c1t1d2s1--swap-no-

-D option can delete a file (or device) from the swap space pool:

# Swap-d/swap/s01

# Swap-d/dev/dsk/c1t1d2s1
