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,
James
