+ That's not exactly what I understood :
+ - there is no comment about using mysql on krampouezh in nodes.pp
+ - it seems more logical to me to have the same server running sql and
+ apache
+ for performance related reasons. ( ie, no network roundtrip )
+ - it is also more logical to have less SPOF by having this on a single
+ system
+
+ I may have missed mails on sysadm, but the only one I found date back

+ october, saying that mysql will be used for blogs :

+ So sure, maybe you told to others people or on irc so you may see my
+ remark as unfair,
+ but I think it would be nice to warn admins on the canonical
+ communication channel, ie
+ here.
+
+&gt;&gt;<i> As krampouezh was planned to be used as a secondary mx, secondary

+</I>&gt;<i>
+</I>&gt;<i> like MySQL server.
+</I>
+ See previous answer. And I think this should be avoided if possible as
+ this mean we have 2 SPOF for the blogs, champagne and krampouezh.
+
+ Given that krampouezh already stopped without notice ( due to
+ a upgrade of a gandi related rpm, as you explained off-list ),
+ I would prefer that we first find what exactly happened before
+ deploying
+ a system where we can be hit 2 times more by the problem again. I
+ didn't
+ upgraded neither krampouezh or champagne for that very reason :
+
+ [<A HREF="https://www.mageia.org/mailman/listinfo/mageia-sysadm">root at krampouezh</A> ~]# urpmq --auto-select
+ gandi-hosting-agent
+ gandi-hosting-vm
+ libpostfix1
+ postfix
+
+ [<A HREF="https://www.mageia.org/mailman/listinfo/mageia-sysadm">root at web1</A> ~]# urpmq --auto-select
+ gandi-hosting-agent
+ gandi-hosting-vm
+ libpostfix1
+ postfix
+
+ Of course, the problem is that champagne do not have enough ram, but
+ then I think
+ we could rediscuss the usage of champagne since it doesn't fullfill
+ newer
+ requirements in term of hosting.
