Recommended options for setting up SDS in a Linux environment

Hi, IBM documentation introduces the following software and file systems as options for setting up SDS. https://www.ibm.com/support/pages/what-options-are-available-shared-disks-sds-ids * Cluster Software IBM HACMP HP ServiceGuard Sun Cluster Veritas Storage Foundation Red Hat Linux Cluster Suite * Cluster File System Global File System (GFS) General Parallel File System (GPFS) Veritas Storage Foundation Cluster File System (CFS) HP PolyServe File System (PSFS) Since Informix tends to be installed on Linux rather than Unix, the choice of Cluster Software or Cluster File System seems to be limited. What Cluster File System is recommended when setting up SDS in a Linux environment? According to the documentation it's GFS, but I'd like to know if there are other options. I would also like to know if there are any cases of SDS being set up and used in a Linux environment.
