      Well manually edit of fstab to be da0 vs da1, finally got around to a reboot of pfsense and now see swap

      I don't really like rebooting my firewall.. Waited for a time when nobody streaming off plex, and wasn't doing anything else, etc.

      I will mark as solved, thanks Jim!

      edit: just to be complete, swapinfo now shows

        @jimp In the case of Squid Proxy and content acceleration I have a 15 gb swap set up it's almost 70 percent full. Is this not the same thing, as it is considered a swap under the proxy ?

        That is unrelated. That is about squid's internal memory vs disk cache. This is about OS RAM usage.

          I'm having the same issue on my brand new 4100; swap partition exists but is not showing in the widget.

          I typed in the command: cat /etc/fstab but not sure where to go from here.

          I'm not sure why it says freebsd-ufs when the disk widget shows zfs...

            See Netgate 4100 disk : my 4100 MAX came with 22.01 pre installed and had a swap partition, but not shown in the GUI dashboard widget.
            Had to edit the /etc/fstab/ as mentioned above.

            This is mine right now :

            [23.01-RELEASE][admin@pfSense.brit-hotel-fumel.net]/root: cat /etc/fstab
            # Device                Mountpoint      FStype  Options         Dump    Pass#
            /dev/nvd0p3             none    swap    sw              0       0
            

            NOte ; back then, see other thread, I had a first line :

            /dev/msdosfs/EFISYS     /boot/efi       msdosfs rw,noatime,noauto       0       0
            

            Now, it is 't there anymore.

            freebsd-ufs when the disk widget shows zfs

            Can't tell ...
            I did do a complete re install with an fresh "22.05" image from Netgate, last September just to complete my 'crash test formation'.

            No "help me" PM's please. Use the forum, the community will thank you.
            Edit : and where are the logs ??

              The 4100 MAX I have here appears to be OK, it was freshly installed recently with 23.01, though. It's possible there was an issue in the older installer.

              I'm curious though if anyone can reproduce that with a fresh 23.01 install.

              : cat /etc/fstab

                  OK, problem solved.

                  I did a fresh install of 23.01 on my 4100-MAX and now the SWAP partition is recognized!

                    @jimp does the 2100-Max have an ability to have a swap partition on the 30GB SSD drive? This is after a fresh install of 23.01 from TAC support provided software.

                      Not by default. And it would be complex to add it.

                      The aarch64 installs are created by imaging the target device directly, there is no installer like there is for amd64. The images used there do not have swap.

                        Since you are running from an SSD you could partition the MMC and drop a swap slice on there if you really want swap but I wouldn't recommend doing that long term unless you're just wanting it for crash dumps.

                        We're considering making it an option to disable swap memory usage while keeping swap for crash dumps but we don't have an option in for that yet.

                            Swap file is ada0s3,

                            I went to cat/etc/fstab:
                            /dev/ada2p3 none swap sw 0 0

                            So is the point at which I can edit fstab and change the ada2p3 to ada0p3? Then reboot pfsense?

                              Yes you could just edit he fstab if you have only one drive now and it has a SWAP partition.

                                @stephenw10 yes that is the case. I have migrated through several computers and I am thinking the incorrect location for the swap file is a remnant of past configurations - dual boot with windows and separate storage drives pre-zfs to store partition images using third party imaging program. When I clean installed 23 pfsense+? and moved to zfs, I pulled in my confiig file off a USB drive on reboot.

                                  Worked like a charm - now the swap partition shows up in the System Information widget.

                                      @jimp Is there a way to enable swap on the 2100?

                                      Other than what's already been mentioned, if you use the new net installer to (re)install 24.03 on a 2100 you can specify the amount of swap space it will define (or disable by setting it to 0). The net installer does not use the old method of writing out disk images, it works similar to the full installation experience on amd64, even on aarch64/arm64.

                                      I would only recommend choosing to enable swap on a 2100 if you have an SSD in there, though.

                                        @The-Party-of-Hell-No said in swap not listed? [solved]:

                                        now the swap partition shows up in the System Information widget.

                                        Now swap is working, you have to observe that is never - yeap, never, gets used.
                                        Afaik, its useful to store crash dumps, so you an do some post mortem, after reboot, analyses.
                                        If pfSense start to actively use the swap, let this be a sign to you to take of load of the system immediately.

                                        This, the "Swp" line, should stay at "zero" always.

                                          Can I in theory utilize the mmc as the 2100 max has a ssd after the fact just format that mmc and configure it for use with 23.05? I only want it for this system panic with use of the compex pcie card, it crashes when it goes full tilt but I canโ€™t get the info without the swap, I donโ€™t want to reinstall I just a temp accessible swap for use with the current issue.

                                            While you could do that with the MMC, I wouldn't. If you have a cheap sacrificial USB thumb drive you could do it to that without worrying about potential harm to the MMC. I don't have the commands handy but you'd format the drive with gpart, add a freebsd-swap partition, then reference that partition in /etc/fstab as the swap parition. Then when you're done, remove the fstab entry, reboot and remove the thumb drive.
