Description

It seems the carp implementation differs from the freebsd standard one, which cannot be used under bhyve.

On a fresh freebsd 10.1 bhyve install i could make carp work:
$ uname -a
FreeBSD darkthrone 10.1-RELEASE-p9 FreeBSD 10.1-RELEASE-p9 #0: Tue Apr 7 01:09:46 UTC 2015 :/usr/obj/usr/src/sys/GENERIC amd64

$/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias
ifconfig: SIOCSVH: Invalid argument

$kldload carp

$/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias

$ ifconfig
...
media: Ethernet 10Gbase-T <full-duplex>
status: active
carp: BACKUP vhid 1 advbase 1 advskew 100

In pfsense the carp module is in the kernel, but i'll get the first error as on a fresh native fbsd install without / before loading the carp module

pfsense $/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias
ifconfig: SIOCSVH: Invalid argument

I tested from early 2.2 RC versions till latest devel version.

I also tested OPNSense la 15.1.9, which had the pfsync / unconsistent changes to carp reversed. Worked there also.

So some custom stuff keeps me away from using pfSense under bhyve with carp (currently running single node only)

Did you try from the GUI since carp should not differ from FreeBSD at least in this regard!

Yes, that's when i checked for details...

cheers,

Just checked with 2.3-alpha, it works there. I don't really know if it's because of fbsd 10.2 or some reversed custom patches?

#4 Updated by Chris Buechler about 4 years ago

  • Status changed from New to Resolved
  • Target version set to 2.3

Thanks for the feedback. Probably going to 10-STABLE fixes (or removal of patches in the process, though those removed largely got upstreamed).

#5 Updated by Matthias Breddin about 4 years ago

So any idea it'll get backported to 2.2.x "soon". Or will 2.3 be released before any new 2.2.x version?

It won't be backported, not likely there will be another 2.2.x.
