[lug] RedHat 7.1 Water Torture and SWAP size

[John Hernandez]

Nate, for the HD access annoyance, I would try incrementally stopping 
processes until the drive access stops.  In essence, use a process of 
elimination routine, for example.

1) Stop KDE/Gnome
2) Go down to run-level 2
3) Go down to run-level 1

You can use 'lsof' to see which files remain open, and what processes 
they are associated with.

As far as the swap issue, you should be able to create a small 
temporary swapfile on an existing partition, see mkswap(8), active it 
with 'swapon [swapfile]', next 'swapoff /dev/hd??', then resize the 
swap partition with fdisk or whatever.  If your swap partition is not 
the last on the disk (outside cylinders), then there's a good chance 
this process will leave a "gap" in your disk where another filesystem 
may be created, but it may be too small to be useful.  You may want to 
consider just using the entire partition for a new filesystem and 
sticking with the "swapfile on a filesystem" paradigm; to make it 
permanent, add it to /etc/fstab.
