Hello,
we have a two node gfs cluster as dns cluster with ipv6 which needs to be
running.
Regularily we get those kernel messages without impacting availability of the
cluster. Any idea why they occure? And if they are worth investigating
further? Seems to be related to ipv6 and gfs locking. Does it?
