GFS2 for SAP HANA

I am trying to find out about alternatives to using NFS for shared storage for SAP HANA. I am working on building a SAP HANA scale-out cluster using GFS2 for the /hana/shared file system, but am interested in knowing if would be possible to use GFS2 for the entire /hana file system across all HANA nodes and effectively be sharing the /hana/data, /hana/logs and /hana/shared all on the same GFS2 mount. Has anyone tried this or considered this and have any insight to if this is possible or not?
