I am running Ubuntu 12.04 on a 64-bit HP laptop with a 16 GB flash drive. I do not have a working hard drive right now. When I installed Ubuntu, I created a 2 GB swap partition on sdb1. I have since learned that swap partitions are generally a bad idea on flash drives, so I would like to use my swap space for my other partitions. You can see my partition scheme in the link below.
I have read that I just have to comment
sdb1 out of the fstab file, boot from a GParted live CD, select
swapoff for sdb1, delete/merge with other partition, and everything's good.
But, I've also read that messing with sdb1 can change the UUID of sdb2 or sdb3 and cause problems. Is this true? Does initramfs use swap at all?
Also, when I get Ubuntu running on my laptop with an internal hard drive, does the swap partition help that much? I have 6 GB of DDR3. Does the rule of 1.5xActual RAM still apply? It seems like quite a bit to me.
Thanks for the help!
UPDATE: I have removed swap. The process I followed is:
- Right click swap partition in GParted and selected swapoff.
- Used # to comment the swap partition out of fstab.
- I tried to boot from a live GParted CD, but I kept getting an error, so I ran GParted in Ubuntu.
- Deleted swap partition in GParted.
- Unmounted /windows.
- Expanded /windows to take the remaining space.
- Mounted /windows.
The / and /windows partitions each kept their own names and UUIDs, and everything is running fine. I have never seen any swap space being used before, and I don't intend to use the hibernate function, so I think removing swap was a good idea.
