cluster

Hello all,

We are looking for web-sites which are running on the highly available Galera Cluster for MySQL.

We know that some installations are out there because there are some Drupal specific configuration parameters in Galera Cluster. But we do not know who it is.

So if your run Drupal on Galera or if you know who is running Drupal on Galera please let mee know.

Thanks,

Hi,

have you ever write something to find graph clusters analysing node texts?
I'd like to write something about...

I setup a MySQL 5.0 Cluster on a spare server with multiple Xen VMs and discovered that Drupal 6 (and most likely D7 as wel) as it exists today cannot function properly under the MySQL NDBCLUSTER engine. It seems that under the NDBCLUSTER engine (also known as NDB), D6 has a table called menu_router that fails to be converted.

I posted a bug report about it under the D6 platform as it is rather detailed, but I have an idea this will affect D7 as well.

I am setting up 2 load balanced servers under 1 ip to run my Drupal sites (multisite installation).
The sites will be using a separate dedicated server for the MySQL databases, on the same rack and 100Mbps network for faster access.
All 3 servers (2 app servers load balanced under one ip and the dedicated mysql server) are on the same physical rack.

Several questions come to mind, in particular...

APPROACH 1: rsync /home directories accross both servers.
