        Yeah it's safe to leave enabled on an SSD. But, as you say, it should never get used anyway.

        We have recommended using a USB drive for SWAP because it's easy to add. In your case it was trivial because the SWAP partition already existed. But on a system with emmc only where there is no SWAP then re-partitioning it to add swap is complex. Easier to reinstall. Or just use a USB drive temporarily.

          Okay Stephen riddle me this... yesterday I was able to get the swap file to show in the gui under system information by editing the fstab to correct the location of the swap file partition. Today I see my amount of swap is 1024 and "gpart show" says I have 1.06 or "freebsd-swap (1.0G)." What kind of trickery is this!

              Unclear what your question is? You appear to have a 1GB SWAP partition and it's configured correctly if it appears in the gui.

                Sorry, I was not clear... the gui, system Information says the swap file is 1024mb but the swap file according to gpart is 1.0g. My thinking is these two should match? Am I wrong about that?

                  Your in luck that is 1GB

                  64MB X 2 = 128MB a fourth of a 1GB

                  128MB X 2 = 512MB or half a 1GB

                  512 X 2 = 1024MB or Also known as 1GB :)

                          Quick Question @stephenw10 @jimp

                          I am testing SWAP on a USB drive and I used gpart to create a swap partition on the drive, I have it referenced and it is working...

                          But it doesn't show usage here...

                          But it does here

                          This all seemed to math up with the SSD use

                          I checked the ada0 made sure it would work unplugged it to make use it was the right drive name also

                              /dev/ada0s3b

                              With use of the drive "da0" in place of "/dev/ada0s3b how can I still use the SWAP and have coredumps generate?

                              How can I still use the external drive for swap and access core dumps in /var/crashes?

                                I need to use

                                /dev/ada0s3b for dump

                                and
                                /dev/da0 for swapping

                                can I separate them?

                                  Not easily. Not as far as I know at least.
