I created a swap partition (8 gb as part of a 250 gb drive).
I formatted the partition as swap and enabled it using:
When I do 'top' or 'free' I can see that the swap is recognized.
Also when I do:
/dev/sda1: UUID="f04e6038-4412-46c4-b58d-67bfe3f8eddd" TYPE="ext4"
/dev/sdc1: UUID="88ee73e8-7556-40fa-b696-fbc15161036b" TYPE="swap"
/dev/sdc2: UUID="7cdc90eb-6a72-48bb-965d-d4423f8f2057" TYPE="ext4"
/dev/sdb1: UUID="dc25bafb-adbc-4a65-845c-02c9253a795e" TYPE="ext4"
However, I had to add swapon /dev/sdc1 as a startup service, because it didn't stick.
Also, I never see any programs use the swap memory (it always says 0 under 'used' when i do free).
I have 4 gb internal memory, that is also not fully used. Is that the reason the system doesn't use the swap memory?
