Ahci(4) needed for TRIM
-
Fantastic tutorial!! Thanks Tikimotel and PTT ;D
Updated tutorial for the ahci_load="YES" to be edited into /boot/loader.conf.local
That way it will persist through firmware updates because the /boot/loader.conf is overwritten during updates as well.
For pfSense 2.1, Enable AHCI and TRIM for SSDs. 1\. Download the ISO of FreeBSD 8.3 and copy the "ahci.ko" into /boot/modules/ 2\. chmod 0555 ahci.ko (r-xr-xr-x) 3\. Check if loads in the console, "kldload ahci" & "kldstat" 4\. Edit /boot/loader.conf.local to add ahci_load="YES" 5\. Reboot 6\. At the loader prompt "mountroot" type "?" for list of options. 7\. At the loader prompt "mountroot" type "ufs:/dev/ada0s1a" (ada0;ada1;ada4 will depend on chipset used) 8\. Once booted edit /etc/fstab and change and save the all mountpoints accordingly, including swap. (ada0;ada1;ada4 will depend on chipset used) 9\. Reboot pfSense will now boot like before if you have edited fstab correctly. 10\. Perform the TRIM_set action at a shell. touch /root/TRIM_set; /etc/rc.reboot to remove touch /root/TRIM_unset; /etc/rc.reboot 11\. Reboot 12\. Check if TRIM is enabled with "tunefs -p /" -
Great, worked right away! I verified the module would load, then edited /etc/fstab, changing ad4 to ada0 and rebooted. I got lucky: with my intel chipset, the SSD came up as ada0
Maybe this should be in the release notes? Or at least point to this thread in http://redmine.pfsense.org/issues/2319. No use in documenting /root/TRIM_set if more work is needed to get TRIM working.
Thanks again

You can get the needed "ko" modules from here:
FreeBSD 8.1: http://files.pfsense.org/jimp/ko-8.1/
FreeBSD 8.3: http://files.pfsense.org/jimp/ko-8.3/
Thanks goes to Jimp ;)
Also say thanks to Jimp about the " xxxx.ko on the /boot/modules/" advice ;)

Thanks jimp! :D
Looks like using rc.conf.local is not really needed, because during update rc.conf is edited, not deleted, so my things added into rc.conf years ago are still working. But to be safe… yes it's not bad to use rc.conf.local instead

@w0w:
I am getting this when trying to get S.M.A.R.T., after ahci enabled, any suggestions?
The device name changed with ahci, ie from ad4 to ada0 in my case, and the extra 'a' is not being picked up by the regexp in diag_smart.php
This change to /usr/local/www/diag_smart.php will pick up the devices with the extra 'a', if it's there.

Thank you charliem!
Hmm, may be it should be submitted here - https://github.com/pfsense/pfsense/blob/master/usr/local/www/diag_smart.php ?Or somebody can do the patch that can be applied with "Patches" package. This one posted does not look compatible.
I have patched manually but…
Patch works via "System Patches" package. Sorry ;) -
Use with caution!
I've cleaned up the "patch" a bit and added one extra for the dashboard widget! ;D1st:

I think this is great, but TRIM on a SSD is so common like dirt by now and required, that it should either be:
1. Something that is just automagically detected and applied (like it does for any other common device)
or
2. Asked at initial install "would you like to enable TRIM on this device."
Maybe next decade.

AHCI is great! for TCQ & NCQ on normal HDD's not just for TRIM on SSD's.
"ada0: Command Queueing enabled"And for SATA 6Gbs support.
ada0: 600.000MB/s transfers (SATA 3.x, UDMA5, PIO 8192bytes) -
The AHCI module should be included in snapshots now (I just updated a VM and checked, it's there).
Also look at /usr/local/sbin/ufslabels.sh - that would eliminate the need to make any fstab edits.
Too late for 2.1 to grow an installer option for it, but perhaps for 2.2.
-
Thanks Jimp, just started a fresh installation on my main pf box using a new SSD and tried out the latest snap. Works perfectly.
Couldnt figure out how to run the ufslabels.sh file. Getting a permission denied at a shell, so just edited fstab the old fashioned way.
-
It's just missing exec bits
chmod a+x ufslabels.sh; ./ufslabels.shOr:
sh ufslabels.shI pushed a fix to correct the exec bits, it'll turn up in shapshots eventually
-
Does that printout look normal with the unexpected operator? End result seems to be correct.

That's not fatal (it was in code to auto-commit the changes if you passed in the right command line parameter), but it isn't relevant to using it interactively, so you can proceed from there.

Looks like SMART is also fixed
https://redmine.pfsense.org/projects/pfsense/repository/revisions/ccf479876283082b39ac9a37c1c6308f4857a6f0/diffThanks jimp!
-
For completeness the smart dashboard widget needs the same fix.

-
I just forgot about the widget entirely in the previous commit.
Done now though:
