Secondary Pfsense Crash after CARP Configuration
-
I am stuck in an issues since last two weeks because my pfsense crashes and went into to endless loop of reboot whenever i configure CARP on seconday pfsense . Even i have tested on different hardwares and different versions old and latest of pfsense . Please if someone can guide
-
You must provide more detail about the crashes. Can you see any part of the error/backtrace/etc that happens? If you disconnect the sync cable does the reboot loop stop?
Are you using any limiters? (Limiters + pfsync is a known panic trigger for HA)
-
Hi
I have the same issue i am using 2.4.2 i followed the following video. https://www.youtube.com/watch?v=gxIPHR-eX_U it works up until enabling carp then send my pfsense in a massive boot loops.
I do have limiters so maybe that could be the issue im facing.

Did you fix this?
-
No it is still an open bug.
Delete the limiters or disable pfsync.

Can you not uncheck the toggle for Traffic Shaper Limiters configuration & Traffic Shaper configuration?

-
If whatever you try works, yes.
It is a problem specific to limiters. The shaper itself (altq) works fine.
-
Thanks. I did try without it checked but still crashed. I’ll delete the limiters and try that instead.

Hi,
I solved mine with this … https://redmine.pfsense.org/issues/4310#note-44

Also been reading that the WAN has to be on the same NIC interface on backup cluster?
Im using vmware on both boxes so does that mean same vswitch?
-
Also be sure you remove all the calls to the limiters in the rules.
Disable state syncing on both nodes and try again. Does it still crash? If so you might be looking at a different problem.
Also been reading that the WAN has to be on the same NIC interface on backup cluster?
ALL NICs have to be the same on both nodes in the same order. If WAN is igb0 on the primary, WAN has to be igb0 on the secondary, and so on. Generally not the source of a panic however, just "unexpected" behavior.
You might want to start again - small, and get WAN+LAN working in a very basic HA pair before moving on to more advanced configurations. They're VMs. It don't cost nothin'.
Both nodes have to be able to pass multicast between each other.
Inability to do so will not result in a crash, however, but a MASTER/MASTER split brain issue.
-
Thanks
I think the problem i have is the interfaces arent the same so ill have to try and move stuff around to get same interface names.
so it has to be the same physical nic its not based on virtual nic?
Mat

An interface has a physical name (em0, re0, igb0, xn0, igb0.1000, lagg2.1001) and an internal name (wan, lan, opt1, opt2, opt3, optX).
They all have to match exactly on both nodes.
Use Status > Interfaces to verify.
This is all covered in detail here: https://portal.pfsense.org/docs/book/highavailability/index.html

Painful lol.
Internally they are all named the same but physical there not so ill have to change some bits around.
few more days of playing then.
-
Ok set up quick test boxes on same host for now. all HA works however cant ping the LAN Virtual IP until i set the MAC as static on the hosts.
Now i can ping but its up and down like a yoyo.
Any ideas?

I have done the
Enable promiscuous mode on the vSwitch
Enable "MAC Address changes"
Enable "Forged transmits"I have VM_Prod for VMS
I now have another port group of VM_Prod-PF and changed pfsense LAN to this port group.
Same problem though.

Sorry. Runs great under XenServer. Someone else will have to help with VMware. It's certainly something in your virtual environment.
Moving to Virtualization.

Thanks for your help up to now anyway.
Anyone had this issue?
Cant ping virtual ip until the following is enabled
Enable promiscuous mode on the vSwitch
Enable "MAC Address changes"
Enable "Forged transmits"Once enabled i start to get ping return but it times out.
