We are in the process of setting up Oracle RAC on Redhat Linux. I need RAC expert's comments for the following questions. 1) What type of filesystem are you using for Oracle datafiles? 2) Are your implementation(s) using raw partitions or a cluster file system for the OCR and voting disks? 3) If using raw partitions with Linux can you describe any challenges you had with device discovery?
