[Linux-cluster] Network hiccup + power-fencing = both nodes go down (redhat cluster 4)

[Jeff Harr]

Well, thanks for your help thus far.  I'm going to keep plugging away.
I "seem to remember" that when I originally tested the config, I'd
unplug the Ethernet from 1 box and the other would take about a minute
before it determined that it had "missed too many heartbeats".

Good luck with that job man,
Jeff

'AH'.  No, if it's blade servers the only network connectivity that you
have is via the blade's management ports.  A lot of chassis give you 2
network connections tho (the egenera & IBM that I've used both do) - but
I
can understand the physical limitations. :)

Not guilty I'm afraid - I've had to stop playing with clustering at the
moment due to looking for a new job :)
