On Monday 20 March 2006 20:53, Jean-David Beyer stood up and spoke the
following words to the masses in /comp.os.linux.misc...:/
The amount of usable swap space in the Linux kernel for IA32 systems is
limited to around 2 GB, give and take a few bytes. In other words,
unless your machine is an IA32-64 - e.g. AMD64 - you're wasting about 6
GB of diskspace... ;-)
I have got a RedHat Linux IA32 but the cpus are 2 dual core Intel Xeon
3.4 Ghz. I agree that a real Linux 64 OS would better fit with my Xeons
but I have to deal with...
In my case, Linux 32 bits (RedHat AS 3.0 32 bits with a
2.4.21-20.0.1.ELsmp kernel _ this kernel from RedHat has some back
ports from kernel 2.6), am I wasting 6 Gb of diskspace on my swap
partition of 8 Gb? How can I confirm it? man on mkswap gives me "The
maximum useful size of a swap area now depends on the architecture. It
is roughly 2GiB on i386, PPC, m68k, ARM, 1GiB on sparc, 512MiB on
mips, 128GiB on alpha and 3TiB on sparc64."
