[Linux-cluster] MySQL + RH Cluster Suite + GFS

[Eloy Acosta Toscano]

Hello, I´d like to make you some questions about or new enterprise database production systems, which should be in production state in about 2 or 3 days. Yes, I´know this is not too much time to deploy a good and definitive HA solution, but I´d like to try making the best possible.

We´ve tried a MySQL with RedHat Cluster Suite H/A solution, but we have very 
bad results in the H/A tests.
We use a iSCSI LUN per node with ext3 FS and a HP iLO as fence device, and I 
think that these poor results are related with these two components: ext3 
formated HD device and a disfunction in the fenced daemon with the HP iLO 
device.

So, I´ve readed in some whitepapers about solutions based on MySQL + RedHat 
Cluster Suite + GFS.
And the question is: Do you think we sould use GFS instead Ext3 FS?
Do you have any information about this kind of solution? Is stable enougth 
solution  for production enviroments? and ¿what about the performance 
results using GFS? will we loose performance?

We have only 2 days to deploy a final H/A solution and your opinion is very 
important to us.

Than you very very much.
