Is there a real problem? There doesn't seem to be any memory pressure as no swap space is used.What's the beef? Are you worried about the RAM you paid for being actually used? [by rgorn]
i'm newbie in linux.gnome warns me that i don't have enough hard space.and when i look i see that i have a 5G swap memory.
and when i look at system monitor i see that linux almost never uses swap memory because i have 4g ram.and swap will be usefull while ram is full.
i want to decrease my swap memory and make it 3g.is it possible to decrease it and add the extra 1g to the root???
Every Saturday, for reasons unknown to me, one of my servers experiences a spike in swap utilisation. It's not necessarily a problem as there is plenty of free memory available, but I'd still like to understand what's going on.
In particular, I'm perplexed by a situation where swap goes from 2% used to 100% used over a period of around 20 minutes.
Today I discovered that my Ubuntu 12.04LTS doesn't have any swap-space.
I installed this system from scratch only some weeks ago. I encrypted all the partitions to me needs. I didn't install any swap space in the first place, cause the installation dialog misbehaved when I tried to set up the encrypted swap.
