The above list
/dev/sda5 14765 4642 9373 34% /
tmpfs 496 1 496 1% /dev/shm
/dev/sda7 34897 4773 30125 14% /media/New Volume
Says your root file system "/" is using 4642MB out of 14765MB and is only 34% filled.
Similarly your ' /media/New\ Volume' ' file system is 14%.
So you don't have any problem with filesystem space.
You can increase the swap. If you have extra space on your disk.
First see if you need to - run the 'free' command ....(if you post the result then use "go advanced" button and put it in code '#' section.to preserve spacing)
[stevea@hypoxylon Desktop]$ free
total used free shared buffers cached
Mem: 7914076 2771232 5142844 0 3568 248724
-/+ buffers/cache: 2518940 5395136
Swap: 8925180 241120 8684060
So my system is using 241.120MB of swap out of a total of 8.925GB. No problems.
If Swap is getting towards full - that's a problem.
You can use 'gparted'
su -c " yum install gparted"
su -c gparted
to create a partition formatted as swap.
Then you can add the nrew partition (/dev/sda6 in this case) to fstab like .....
echo "/dev/sda6 swap swap defaults 0 0" >> /etc/fstab
Then you'll have the new swap (plus the old one) available after reboot.
You can also edit /etc/fstab as root, but be careful !
I suggest you load the 'htop' package and run the command of the same name to see what if anything is using your CPU time and memory space. The 'top' command is a little different version of the same idea. These are non-gui tools run in a terminal.
