My Centos 5.3 cluster has major network stability issues
(these are the dom0's) when running xen 3.4 and 3.4.1. Things were rock solid
when running 3.3.1 and they were again when we downgraded back to it. Are there
any known network issues with the 3.4.x group? Did something change with 3.4
with how networking is done that we might have needed to change? The guest
networking worked fine afaik, but every hour or so, the dom0 would get fenced
by another cluster member and its more than likely because of some type of
networking change (maybe like the network service getting restarted or whatever).
I couldn’t get any useful info out of the logs, but only happened on
nodes that were running 3.4.x and it only happened if guests were running on
it. Everything was fine if no guests were running. BTW, we tried changing
kernels and that didn’t make a difference either. Current with centos is 2.6.18-128.7.1.el5xen,
but our cluster was the most stable with 2.6.18-92.1.22.el5xen #1 SMP Tue Dec
16 12:26:32 EST 2008 x86_64 x86_64 x86_64 GNU/Linux and xen 3.3.1. Obviously
for security and performance reasons we want to stay current
Any help is sincerelly appreciated!
