Simple question, I have some servers that were running 10.04 that I upgraded to 12.04.

So they were installed using 10.04 (kernel 2.6.32* I believe) and the version of ext4 that shipped then.

By upgrading to 12.04 and the newer kernel, does that enable TRIM automatically? (Do I need to add 'discard' to the fstab?) Or do I need to do a clean install of 12.04 to get TRIM functionality on those drives.
