I think you're onto something.

25.07-RELEASE][admin@vpnspare.mgmt.blah]/root: /bin/cat /etc/fstab | /usr/bin/grep swap | /usr/bin/awk '{ printf $1 }' | /usr/bin/head -n 1
/dev/ada0p2/dev/ada1p2[25.07-RELEASE][admin@vpnspare.mgmt.blah]/root:

cat /tmp/fstab.swap
/dev/ada0p2/dev/ada1p2 none swap sw 0 0

That doesn't look like a correct device, so it's quite likely that this breaks it. We have 4 Netgate 7100's which are like this, with two SSD's built in. We got them delivered like this, no modifications done (except for a broken PSU two times).

On 24.11 it works just fine, and probably on all previous versions we used as well in the past 3 years or so.

On 24.11 it looks like this:
/root: swapinfo
Device 1K-blocks Used Avail Capacity
/dev/ada0p2 1048576 0 1048576 0%
/dev/ada1p2 1048576 0 1048576 0%
Total 2097152 0 2097152 0%

root: cat /tmp/fstab.swap

Device Mountpoint FStype Options Dump Pass#

/dev/ada0p2 none swap sw 0 0
/dev/ada1p2 none swap sw 0 0

Thanks, Jos

Aha! Ok let me do some digging here....

[stephenw10]

Ah, already reported in 2.8: https://redmine.pfsense.org/issues/16232

Looks like an easy enough fix though. Patch incoming....

[stephenw10]

Ok this works for me: 175.diff

It's a very simple (one character!) change so you might just manually edit the file. Let us know if you're able to test that.

Just tested the patched pfSense-rc on our spare unit.

/etc: diff pfSense-rc.org pfSense-rc
590c590
< SWAPDEVICE=/bin/cat /etc/fstab | /usr/bin/grep swap | /usr/bin/awk '{ printf $1 }' | /usr/bin/head -n 1

SWAPDEVICE=/bin/cat /etc/fstab | /usr/bin/grep swap | /usr/bin/awk '{ print $1 }' | /usr/bin/head -n 1

Works like a charm:
: swapinfo
Device 1K-blocks Used Avail Capacity
/dev/ada0p2 1048576 0 1048576 0%
/dev/ada1p2 1048576 0 1048576 0%
Total 2097152 0 2097152 0%

I'm planning to upgrade, but still on 24.11 and I have ZFS mirror with GEOM mirrored swap, would this problem affect my system or is it just for systems with multiple separate (non-mirrored) swap partitions on the both drives?

[stephenw10]

Try running the new command in 24.11: /bin/cat /etc/fstab | /usr/bin/grep swap | /usr/bin/awk '{ printf $1 }' | /usr/bin/head -n 1

If that returns a valid device it will be fine in 25.07.

Either way it won't prevent you upgrading. And you should just be able to apply the patch afterwards to regain SWAP. If you need it.

@stephenw10
It returns "/dev/mirror/swap" so guessing it should be ok.
Never had pfSense using any swap, but better safe than sorry... :)

[stephenw10]

Yup should be fine.

As expected, also works just fine on 25.07.1-RELEASE.
