the swap space for the newer kernels (if you have it configured to use swap space correctly) will need to be double the ram

I know that, but how do I actually set the size of the swapspace, without having to repartition and thus lose all the data on the disk?

Also, how do I configure the swapspace? I hven't done anything to it since I installed RH7.3, I just let the setup (anaconda) do it for me?

Well, you do need to make space to get space, but with an EXT2 parttion both Parted and Partition Magic can shrink one part to allow the increase in a swap.

With two HDs, this is is loads easier, you can move all the things from the one part you want to shrink off of one HD entirely, wipe old part, then expand the one you want expanded, then make new smaller part, then move the stuff back into the new part.

I have been known to temporarily install a smaller HD just to hold stuff if absolutely must-- this is usually faster than a backup.

Try going to http://www.gnu.org/ and looking in the manual for parted, especially chapters 5,6 and 9 (this is online stuff in HTML if you want it that way).

That's cool. I will later tell you how fast an 800JB Western Digital is-- would you belive there is a dealer in Georgia selling them for $107.00 plus shipping???

I'm sure you meant 80.0 GB's. Which model?

800JB is model number, it is the "special edition" 80 GB with 8 MB Buffer-- 7200 RPM, ATA\100, Caviar(Western Digital). My 40's are 400BB, 2 MB buffer, ATA\100. With HDs, buffer size increase can help with a fast box if the O/S can use that right-- I understand Linux can, will see how hard it is to do.

Series with WD go like this:

Size is GB plus one zero, 100 would be 1000 in WD model number.

AB is always a 2 MB buffer 5400 RPM series.
BB is a 2 MB Buffer 7200 RPM series.
EB is a very TINY buffer(about 1\2 MB last I looked) 5400 RPM series.
JB is a "special edition" series, 8 MB buffer and 7200 RPM.

All these are currently ATA\100 except you might check the specs on the new 1200JB if you NEED an ATA\133 with a 3 Year warranty(the throughput on that might make you think twice).

This dealer got a hold of a bunch when they bought a bunch of 1000JBs and 1200JBs-- they are selling at reasonable prices, buying in posibly pallet lots. So, given that myparts cost limit was $110.00 for the HD (I needed some other stuff for other folks)I got an 80 GB one.

Google Monarch Computers if you are interested. For soemthings they are VERY good (Western Digital HDs especially, if you buy a few and spread the shipping costs, as they ship FedEx.). $70.00 each for a 400BB is not bad either.

I've been along to buy 2 whole machines (all parted out) from Monarch before, except to avoid shipping I just drove out to Tucker to pick the stuff up. Its a good little business.

Yes, but from 2\3 down the panhandle of Florida, it is a wee trip for me. They are quite good at doing Linux boxes, though. And Tyan mobo based boxes-- which was how I found them in the first place.
