Linux Clusters and Patching

[Bob Moriarty]

Currently on 5.8.4 on AIX 6.1 (HA)

I am being nudged to return to Cloverleaf on Linux after a two-year run on AIX (uptime = 575 days).

1) Anyone out there running on a RedHat cluster?

2) Is cloverleaf “cluster aware” on RedHat?

3) What is your RedHat patching schedule? Does it entail downtime? Do you selectively pick patches or just apply everything that RedHat releases?

4) If on a RedHat cluster, can you patch the passive node, failover to it, and then patch the former active node?

Many thanks in advance. I searched clovertech prior to posting but couldn’t find answers.

Apologies for any ambiguities in the use of the term “cluster”. I was referring to high availability, two-node, active/passive clusters.  If anyone has implemented cloverleaf on a (to me) more complex load-balancing cluster (with high availability), I would be interested to know more about your configuration.
