 Its the same on the backup machine, except for the different IPs for fxp0

 Hello Rakhesh,
 
 I never had hash errors on startup for CARP, but for demote, promote you 
 should try /usr/ports/net/ifstated. It's working fine for me.

Any news on this ? I see the same problem on our freebsd + pf + carp
installation...

Cheers,
Norman

Re: CARP and FreeBSD 6.3: is it working for someone?

2008-01-25 Thread Andrea Venturoli 

Sorry to step in this way...
I was planning to upgrade a 6.2/amd64 SMP box to 6.3, hoping I could rid 
myself of those deadlocks that are still occasionally plaguing that server.

Now I read this thread and stopped, since I'm also using CARP on that one.

Can someone confirm CARP works on 6.3 for them?



 bye  Thanks
av.

CARP and FreeBSD 6.3

2008-01-24 Thread Rakhesh Sasidharan 

Hi,

I have two machines. Each have two interfaces, xl0 and fxp0. And each 
have two carp interfaces -- carp1 (xl0 of both) and carp2 (fxp0 of both). 
One of the machines is master, the other is backup.


I also have the following sysctl set: net.inet.carp.preempt - 1

My understanding is that if I down one of the interfaces on the master 
machine (say ''ifconfig xl0 down''), then both carp interfaces on the 
master will be marked as down. And the backup will become the new master. 
Later, when the interface is marked up (''ifconfig xl0 up''), the old 
master will resume control. This is my understanding and that's how things 
were till yesterday (when I was on FreeBSD 6.2/i386 with both machines).


Today morning I upgraded both machines to FreeBSD 6.3 and that does not 
seem to be the case any more.


Now, on the master machine when I down the xl0 interface, only carp1 (the 
group containing xl0) goes into init state (and the other machine's carp1 
interface becomes the new master). Ditto for fxp0 and carp2. So in 
essence, the net.inet.carp.preempt=1 sysctl does not seem to be working as 
expected which is unlike how things were in FreeBSD 6.2.


Has something changed with regards to carp between FreeBSD 6.2 and 6.3? 
Any one else encountering a similar problem?
