Yup. I believe it's something we're actively working with Sun on, because other clustered fil systems (like Compaq's) perform fine. Sun's is just too slow for some reason.

Bruce Pihlamae, long-term Oracle DBA -----Original Message----- [EMAIL PROTECTED] Sent: Friday, March 14, 2003 8:39 PM To: Multiple recipients of list ORACLE-L Attached in a quote from an Oracle Rep, asking us to avoid Global file systems on Sun Cluster nodes for 9i RAC. It is very clear that binaries and/or datafiles on GFS are not supported today. The reason for this is the proxy I/O that GFS is based on can be a real performance and scalability bottleneck. However, The use of GFS for archive logs is the one circumstance where GFS may work for you. The caveat here is that this has not been well tested. Noone internally at Oracle is actively testing with GFS in any capacity today, and I'm not personally aware of any customers who have done this. As a best practice recommendation, we suggest it be avoided altogether. However, if you have the luxury of time to be able to test performance both in standard operational peak loads, and the various backup and media recovery scenarios where you would need to access the archive logs, then you will not get any push back from Oracle Support saying "you are running an un-supported configuration, we can't help you." Is this true?
