The swap size at ISL time is limited to 2GB.

If you want to add more swap, you will need to edit

/etc/swaptab

and add up to 256 entries in this file.

A line in the file is defined as:

Device_name start_offset size

Device_name can be either a block device or standard file.

The Device_name must be specified by a full pathname.


size (in 512-bytes blocks) can be up to 2GB maximum.

If the Device_name is a block device, you can use a "-" meaning that
the entire size of the Device_name will be used. Note that in this
case the size of the block device cannot exceed 2GB.

If you have specified a standard file as a swap file, you will need to
create an empty file with at least the size of blocks specified in
/etc/swaptab (If size was "-", make sure that the file will be created
with less than 2GB size).

Use the following commands (as superuser) to create the empty file:

ulimit unlimited
dd if=/dev/null of=< swap -c

The modification made on /etc/swaptab will only be used after the
reboot of the system. If you want to you the new added swap, use the
following command:

swap -a <
