Adding Swap Space Solaris 10

If you want to add swap space, do the following:

1. Become a superuser (root) by typing:

% su

Password: root-password

2. Create a file in a selected directory to add swap space by typing:

mkfile number[m|k|b] /directory/swap-file-name

where number is an amount of swap space, followed by either m for megabyte, k for kilobyte, or b for block. The directory is a directory in which you have permission to add swap space. The swap-file-name is the name of the swap file you are creating.

For example, to create a 16-megabyte swap file named 16mswap in the foo directory, type the following:

# mkfile 16m /foo/16mswap

See the mkfile(1M) man page for more information.

3. Verify that the file was created by typing:

# ls -l /directory/swap-file-name

The new file appears in the directory. For example:

# ls -l /foo/16mswap

-rw------T   1 root     other    16777216 Dec 12 14:24 /foo/16mswap

4. Run the swap command to specify the additional swap space by typing:

# swap -a /directory/swap-file-name

5. Verify that the extra swap space was added by typing:

#swap -s

The output shows the allocated swap space. For example:

#swap -s

total: 289336k bytes allocated + 27008k reserved = 316344k used, 298336k available
