[CentOS] iSCSI / GFS shared web server file system

We currently have a MD3000i with an iSCSI LUN shared out to our apache web 
server. We are going to add another apache web server into the mix using 
LVS to load balance, however, I am curious how well iSCSI handles file 
locking and data integrity. I have the iSCSI partition formatted as ext3. 

Is my setup totally flawed and will ext3 not allow for data integrity with 
multiple apache hosts reading/writing to the shared storage? Am I required 
to also setup GFS across my apache hosts or does iSCSI somehow manage this? 

Thanks for helping clear this up,
