SG2100 128GB SSD and Swap

[stephenw10]

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 :)

@stephenw10 Thank you.

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

Just to confirm this is correct right I can hear the drive running seeking etc

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

Disregard I spoke to soon...

/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?

[JonathanLee]

I need to use

/dev/ada0s3b for dump

and
/dev/da0 for swapping

can I separate them?

[stephenw10]

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