[Linux-cluster] two node cluster update



Hi list,

I'd like to know if there is a "best practice" for updating* a two-node (active/passive) cluster with qdisk. May I start with the passive node ? Can it become dangerous if the passive node run differents packages from the active node ?

Here are my packages to update.

from                                   |     to
------------------------------------------------------------------------------------------------------
openais-0.80.3-7.el5          |   openais 0.80.3-15.el5
cman-2.0.73-1.el5_1.1       |   cman 2.0.84-2.el5
rgmanager-2.0.31-1.el5    |   rgmanager 2.0.38-2.el5_2.1
ricci-0.10.0-6.el5                |   ricci 0.12.0-7.el5.centos.3
modcluster-0.10.0-5.el5    |   modcluster 0.12.0-7.el5.centos


Thanks.
Eric.
