Hello,
I have a strange issue. When I log to node A via HTTP, B shows in red (but I can browse summary, storage and so on).
If I log to B via HTTP, a shows as red. Output from A:
And B:
So as you can see on node A, there B seems to be down. I can ping them both ways
and ssh from A to B and B to A. But still it shows as offline. It happend after some reboots
(I was testing failover). Any idea why? Those are test boxes but I would like to know
how to fix that beforge going into production.
