Hi,
carp(4) states:
"When the option is enabled and one of the carp enabled physical
interfaces goes down, advskew is changed to 240 on all carp interfaces."
in case preemption is enabled. Can anyone give me a hint why this is
limited to a failure of the physical interface?
I had some floods on my firewall which caused the external interfaces to
drop packets (including the carp packets I assume) which was leading to
a takeover of the external carp interface only.
This of course left the cluster in a non-functional state until
preemption switched back the external carp interface to the flooded host.
I wonder if this is intended?
regards
Tim
