Hi all,
Finally bought a new SSD (OCZ Vertex 2 60GB) to run Arch on. I installed it all fine and its all running brilliantly after fighting with XFCE4 and then Gnome 3 for a while (now got Gnome 3 fallback running compiz WM and its much nicer).
One problem I do have is with TRIM. I have the EXACT same hard drive running Ubuntu 11.04 and TRIM is working fine. The /etc/fstab for my Ubuntu install is:
And when I run the TRIM test found here it returns the desired result (all 0's after deleting a file and re-checking the sectors).
Now when I run that test on my new SSD, it doesnt clear the sectors. I have tried everything to get it to work, moved SATA ports beetween SSD's to check BIOS issues (works fine on Ubuntu in both ports, fails in Arch in both).
I downloaded the OCZ firmware upgrader tool and upgraded them both to 1.33, again Ubuntu works and Arch doesnt.
I added "discard" to my /etc/fstab for Arch along with noatime etc as per the guide. Anyone got any idea why its not working? Here is the /etc/fstab for my Arch:
From what I can remember without booting into it, My ubuntu install is on 2.6.38.10 and my Arch shows "3.0" on uname -r.
Any ideas chaps?
