[ale] how do I increase Linux swap file size?

[Richard Faulkner]

Agreed...GParted should do the trick.  I would do some reading if it
were me to confirm that you 
can fulfill the "non-destructive" part of the requirement.  But I also
agree on the necessity of creating 
a larger swap file.  If you use hibernate you'll need to have RAM ==
Swap (correct me if I'm wrong)
otherwise it would be more to do with if you really use that much swap
and if you really need to 
increase it.

Sounds like a straight forward job for gparted.

You may need to boot from a run-live to do it, so the file systems are
not mounted.  You can do it manually with resize2fs and others but if
you don't really REALLY know what you are doing, it can be a receipe for
disaster.  Highly recommend going the gparted route.  It will be time
consuming, if you are moving the start point of an existing partition,
then it can become very time consuming, especially expanding a partition
and moving it up on the disk.  Just deal.  It will cost you some time to
let gparted redo the partitioning but it will be done correctly.  It
will also deal with resizing the file systems if you don't have anything
real bizzare.
