OK..
Here's a thread where you can post all those little dumb mistakes we make and which Ubuntu works out (or works around.)
Here's my offering......
Dumb user bit:
Decided to tidy up and wipe my free space. so do the usual 'dd' command with 'urandom' on all my free space (over 2 drives), then i decide to clean out my 2Gb swap-file partition using the same command!!
So I ran 'Swapoff' and set about running the 'dd' command again on the partition with the swap file.
So after the wipe is finished i decided to reboot.
2 weeks later i noticed that conky is showing my Swap file is running at 68%!! (it's never went above 15% in the past!). Here's me thinking i've got a rouge bug or process or worse a trogen on my system!!
Turns out i've not been using my 2Gb swapfile but a smaller 200Mb swapfile Ubuntu set up when it could not find the UUID of my old (now scrubbed!) swapfile!!
Smart Ubuntu bit:
The OS ran fine on that 200Mb Swapfile! so much that I never noticed ANY slowdown. If I remember Windows in the same situation (no pagefile) it would scream blue murder at me the second it rebooted!!
Quick edit of 'fstab' with the correct UUID then a reboot and i got my 2Gb swapfile back!
I'm thinking of changing that 2Gb swap partition down to a 500Mb one. leave more room for root :D:D
But wil lwait and see how much swap i use when i upgrade from 755Mb up to 1Gb or ram... :D:D
