http://ubuntuforums.org – Hello, I have a powermac running 12.04, and I read somewhere that there are patches for the kernal that add TRIM support. Can I get this for my machine, or is this an Intel only thing? (Hardware)

Mach ssd zif 42 weeks 15 hours ago

Hi everyone,

I just upgraded my laptop to a Mach 120Gb ZIF SSD. Unfortunatly it does not support TRIM but it does do Garbage Collection Support (?)

Having my server running of an OCZ with TRIM I know I want to make some changes for F17 to play nice with my SSD. But since it is not TRIM supported, what should I do.

Special software?

I installed a new box with F17 with all updates.

The box has an SSD drive that is part of a RAID-1 array.

/boot is also on this SSD on a regular partition.

I have configured for TRIM(discard) but no TRIM seems to be occurring.

I have done the following to support TRIM:

Code: checked that the SSD supports TRIM by running hdparm -I /dev/sda

added noatime,discard options in /etc/

If someone gets an SSD that has TRIM support in the firmware and loads Fedora 12, does the I/O layer have support for TRIM yet? Or is it something where you need to add a flag to the kernel at boot time?

TRIM support on SSDs 3 years 15 weeks ago

Does Suse have any software based TRIM support available or that is in the works?

I know there is to a degree new firmware becoming available that supports TRIM (although some are pretty rudimentary) but windows 7 does a fairly good job software side and upgrading the firmware occasionally involves the unbridled joy that is wiping the drive and starting again.

SSD, Linux kernel, and TRIM 2 years 25 weeks ago

Hello all,after a HDD failure a week ago forced me into replacing it + reinstalling my OS, I went for an SSD and also took the opportunity to migrate from Windows (Vista) to Linux (CrunchBang). Very happy with my decision so far!

All you have to do really is open up /etc/fstab and add the "discard" option to the partition you're trying to enable TRIM on.Also, here is a random question for you.I've messed up my Tint2 config file pretty bad with experimentation, how would I go about resetting it?

CompuLab unveiled two hard disk drive-equipped versions of its tiny, Linux-based, Nvidia Tegra 2 powered computer, a discounted price on its Trim-Slice Pro Dev-Kit, plus Trim-Slice support from Arch Linux and MeeGo's Smart TV group. The $319 Trim-Slice H250 includes a 250GB drive, while the $279 Trim-Slice H Diskless lets users add a disk of their own, says the company....

I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space.

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?
