[Linux-cluster] mysql and GFS

[Benoit de Mulder]

Hello, 

The setup is the following : 4 mysql server, today using replication,
around 600 con / per server. The issue is that the write is overloaded
and It's not possible to change the app.

I was looking at two approaches. 

1) Multiple write servers and GFS 

I would like to know if this possible to use multiple write server on
the same database, using external lock parameter on mysql to ensure
data integrity. Does someone has setup a multiple write mysql server
using GFS ?

2) MySQL clustering 

My only fear is that the solution is very young and storage engine
does not support some characteristics of the db schema (ie full text
index).


Any advice will be appreciated. 

Thks
