[Linux-cluster] Freeze with cluster-2.03.11

[Nick Lunt]

I have to suggest purchasing solaris, hp-ux or AIX for running enterprise
clusters.

Having been using Linux for over 10 years it is still not ready for
production clustering. The lack of decent documentation and the number of
cluster software updates that shaft your production systems is a joke. I
often wish I'd never learnt Linux and stuck with solaris instead.

Just my 2 cents worth but if you need to run a production server do not use
Linux Cluster GFS unless you like your boss giving you grief.

I umounted the GFS filesystems on all nodes and ran fsck on all of them, 
just in case.

Some unused inodes, unlinked inodes and bitmap differences were fixed. 
After bringing up everything, in half an our one node get frozen again,
without starting/running mailman :-(. Sigh. The pressure is mounting to 
fix the cluster at any cost, and nothing remained but to downgrade to
cluster-2.01.00/openais-0.80.3 which would be just ridiculous.

Anything else we could do to stabilize the cluster nodes?

Best regards,
Jozsef
