...performance in my Linux Box, herewith is my environment details : 1. We are using RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3. Oracle RDBMS : 9.2.0.4 RAC with 5 Nodes 4. Storage = EVA 6000 with 8 TB SIZE 5. We have 1 DiskGroup and 51 LUNs configured in EVA6000. My Question is : 1. It takes arround 15 minutes to mount arround 51 ocfs file system, is this a normal situation? 2. I monitor the OS using VMSTAT without starting the RAC server, column IO (bo and bi) it's giving 3 digits value continuously, then I unmount all the OCFS filesystem, again monit...

Hello, It is not total off-topic since almost all connected servers will be RHEL and CentOS. :) We are considering to purchase new storage system. The most probably we will be choosing between HP (EVA6000), EMC (CX3-20C) and Hitachi (similar model). iSCSI connection is also required. What are your experienced with listed systems? What to avoid? What ot expect? Now I just know that sequential read/write preformance on EVA is poor. :) Thanks, Mindaugas

Hi OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

Hi All, we are using Red Hat 2.1 Kernel e38 along with MSA 1000. ocfs version being used is $ rpm -qa | grep ocfs ocfs-tools-1.0.10-1 ocfs-2.4.9-e-enterprise-1.0.12-1 ocfs-support-1.0.10-1 Database Version is 9.2.0.5 However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete. We initially assumed RAC is
