      added the following

      Login with SSH or locally and open a shell
      Run /usr/local/sbin/ufslabels.sh
      Add ahci_load="YES" to /boot/loader.conf.local
      Reboot

      touch /root/TRIM_set; /etc/rc.reboot

      When i try to boot in single user mode i get a kernel panic.

      Hardware
      Supermicro SuperServer 5018A-FTN4 with 16GB ECC ram. 
      Samsung pro 120GB SSD.

        Did you set the SATA controller to AHCI mode in the BIOS?

          You may try this instead in single user mode:

          /sbin/tunefs -t enable /

          After that reboot and then run tunefs -p /

          The touch /root/TRIM_set; /etc/rc.reboot has been removed in the newer version.

            Hi,

            Took a look, and it does seem that this allows enabling TRIM - that's great. But I do have a couple questions,

            • is there a way to check what the current state is?
            • if TRIM hasn't been on so far, is there a way to tell the SSD / BIOS to clean up the SSD?

            Thanks!

              cfipilot - have you been able to get TRIM working? I have pretty much the same hardware except only using 8GB ECC RAM for now. I have a Samsung 840 Pro 120GB, is that what you are using?

              I wrote in another thread which was a bit newer (dealing with 2.1.1 as opposed to 2.1), but maybe the issue is hardware specific or it could just be my lack of FreeBSD knowledge…

              @3vian:

              I seem to have a problem with the TRIM enabled setting remaining after reboot.

              Once I executed /sbin/tunefs -t enable / what exactly should I do. I can't run /etc/rc.reboot because I get the following:

              lockf: cannot open /tmp/config.lock: Read-only file system
Cannot reboot at this moment, a config write operation is in progress, and 30 seconds have passed

              If I just exit single-user mode then when restart and /sbin/tunefs -t enable / it indicates it is disabled.

              FYI - already added ahci_load="YES" to /boot/load.conf.local

                cfipilot - Btw, I managed to get it enable.  See below.

                @3vian:

                Seems you have to use /sbin/reboot as mentioned below to reboot

                FYI - it should /sbin/tunefs -t enable /, not /sbin/tunefs -t / as mentioned below.

                @spid:

                @dstephens80:

                Charlie,

                I will give v2.2 a try and let you know how it goes.  As far as dmesg, I can provide nothing as the system will not boot with AHCI enabled.  it will not detect any GEOM devices, but it will boot fine if I remove the ahci_load="YES" from /boot/loader.conf.local.

                Did you convert fstab to ufslabel before adding ahci_load="YES" ?

                Run the following script to do it:
                /usr/local/sbin/ufslabels.sh

                then if it boots correctly go in single user mode and enable TRIM with:
                /sbin/tunefs -t /

                reboot with:
                /sbin/reboot

                and after a reboot check if it's enabled with:
                tunefs -p /

                  Hi,

                  Sorry, trying this on v2.2, not sure if I'm doing something wrong, but here is what I get …
                  Entered: tunefs -t enable /

                  Then the result is ...
                  tunefs: issue TRIM to the disk set
                  tunefs: /: failed to write superblock

                  And checking tunefs (tunefs -p /) ... nope, it's still off. Thoughts?

                  Thanks!

                    arrmo - It sounds like you are not in Single User Mode. Reboot and at the boot screen use option 5 and enter /sbin/tunefs -t enable / at the prompt and reboot (using /sbin/reboot).

                      Will do, thanks! Saw that part, wasn't sure if it was key … seems it is ...  ;)

                      This setting is permanent (when done this way), right?

                      Thanks again.

                        Hi Everybody,

                        I also have the 5018A-FTN4  with a SSD and would like to turn on TRIM.
                        Unfortunately I am not able to enter the Single User Mode to turn it on, as it gives me a
                        panic: AP #1 (PHY# 2) failed!

                        @3vian: You seem to have gotten it to work. How did you manage to get into the Single User Mode?

                        It would also be very handy to start a "best practices for installing pfSense on a 5018A-FTN4 thread", as they seem to become very popular, with all the relevant BIOS settings.
                        Some pfSense tweaks are already mentioned here: https://forum.pfsense.org/index.php?topic=75015.0

                        As always: thank you very much for any info!
                        Harry

                          Just imagine the day when there is a simple check box for "Enable Trim" in a system menu…

                          Alot to ask, I know but we can dream right?

                            I appreciate this post.

                            I came into all of this being a n00b w/ command line, so if I overlooked something simple, be gentle.

                            I've tried everything & can't seem to get anything working.

                            Here's what I've done after upgrading to 2.1.5 (SSD is an intel 320 160gb, has TRIM):

                            1. Logged in as single user (selected 5), but there seems to be a slight issue with the mount & asking me to specify a path while booting. I can provide that info later on. Anyways, I tell it to skip that & it loads up pfsense perfectly, everything works. Loads fine with multi-user.

                            2. Input what you said & got this:

                            [2.1.5-RELEASE][root@pfsense.router]/root(10): /sbin/tunefs -t enable /
                            tunefs: issue TRIM to the disk set
                            tunefs: /dev/ufsid/53f426d4c691b578: failed to write superblock

                            I can log in as root or admin & I get the same response. Other responses to things I've tried from this thread include "bad trim" &  one other statement I forgot to write down.

                            I'm tempted to reinstall from scratch as it doesn't take that long to do & try again. I've been down that road, but I wonder if going back to a pre "/usr/local/sbin/ufslabels.sh" point in time may help as that seems to change the characteristics of the drive.

                            Also, this line always trips me up: ahci_load="YES" to /boot/loader.conf.local

                            [2.1.5-RELEASE][root@pfsense.router]/root(33): /boot/loader.conf.local ahci_load="Yes"
                            /boot/loader.conf.local: Permission denied.

                            Thoughts?

                              That's not something you run at the command line. You have to add the line:
                              ahci_load="YES"
                              to the file  /boot/loader.conf.local
                              You can do the using the webgui in Diagnosics: Edit File: or from the command line using the built in ee editor (or vi if you're a masochist!).
