But there are two options depending on your partitioning scheme and/or free space on other partitions: 1) Add another swap partition if there is un-partitioned space 2) Add a swap file on an existing partition. man mkswap will give you the details. === To: redhat-list@redhat.com From: Javier Gostling <jgd@samwan.homeip.net> Subject: Re: Help --need to increase swap partition on RH9 Date: Thu, 24 Jul 2003 16:51:19 -0400 On Thu, Jul 24, 2003 at 01:32:25PM -0700, James D.

The 2:1 swap/rap ratio is just a thumb rule, and need not be followed strictly. Now if you really want to increase swap space, the easiest path is to just add a second swap partition. Linux will spread swap usage among all active swap areas. === To: redhat-list@redhat.com From: "Leonard den Ottolander" <leonardjo@hetnet.nl> Subject: Re: Help --need to increase swap partition on RH9 Date: Thu, 24 Jul 2003 23:05:27 +0200 Hi James, > How can I increase the swap size on production system?

Another option is to create a swapfile on a partition that has enough space left. In the case you use /home for this the procedure would be: # dd if=/dev/zero of=/home/swapfile bs=1k count=Xk # mkswap -f /home/swapfile # swapon /home/swapfile Dont forget to add /home/swapfile to /etc/fstab. Using /home might not be the best option from a security standpoint, but it is probably the partition with the most free space left... ===
