multiple identical swap files in /etc/fstab

joseph wholey — Thu, 26 Oct 2006 11:41:31 GMT

Running RHEL AS3. When I look in the /etc/fstab file I have multipe swap definitions as follows:

/dev/sda5 swap swap defaults 0 0

Any ideas? thx.

That is not a problem, you can have multiple swap devices. You can check your active swap with swapon -s.

Multiple swap devices are used to balance the load between disks.

It also was stated that swap devices cannot be larger than 2 GB, and multiple swap devices where created to have larger swap space. This size limitation is not a restriction anymore.

Ivan, when I say multiple identical, I really meant, "multiple identical..." i.e. the same device.

It's not correct, just see the output of swapon -s to view the active swap device.

Maybe, some "yank/paste" problem. Remove the duplicate lines.
