increase swap partition
Hi All,
I have upgraded from 4GB RAM to 16GB. I feel like I should increase the swap partition. What do you think, shall I and how can I do this? Especially using RAID-1 I'm not sure whether I shall/can just use parted or alike.
Thanks a lot
Loco

One option might be to create a swap file, and place that on the data volume (or even a dedicated SSD volume).
Not something I've tried, but it seems to me that it should work, and is probably more sustainable than repartitioning the drives (e.g., it can easily be put back in place if you ever need to do a factory reset).

Is there some application you want to run that requires swapping?
Hi Stephen,
thanks for the quick reply. The answer is YES I'm running virtualbox on the system so it may happen that swapping is required.

Hi Stephen,
thanks again for your feedback. I will try with the swap file sounds most reasonable to me.
