Re: [SSI-users] Node not joining cluster

[Ron C. <ro...@de...>]

What I noticed with some machines that I had to boot with etherboot is that when
it connected initially to the cluster it connected at the right speed (In my
case 100Mb/Fullduplex).

After etherboot downloaded the bootimage I saw (on the switch) that in some
cases fullduplex wasn't there anymore or that there was a speed mismatch (some
nodes fell back to 10Mb/halfduplex). What I did was make sure that all machines
had an updated bios and used a utility to set the ethernet card to
auto-negotiate (the switch is setup like that too).

I noticed that when there's a speed mismatch that it can take forever for a node
to join the cluster. I had nodes that took 45 mins to join.
I also had "the whole cluster" not respond until the node had joined. Once the
node did join it seemed ok but when an application was migrated to that node, or
when I started diskio (or tcp/ip traffic) from that node the cluster again
wouldn't respond.  (Besides that I had another bunch of weird problems too, for
example Executing "cluster -v" took up to 10mins or so, that were resolved once
I had the speed mismatch figured out)
