Hi, I'm new to OCFS2 and have a question about my setup. I have two SLES 10 nodes (no patches yet) and a single OCFS2 volume. The volume receives live data via replication to keep it up to date. The goal is to have node one receive replicated date and all nodes run reports off this date. Today I am just using two nodes to get started.
The shared storage is an Openfiler 1.3 system running iscsi. Our numbers for raw read and write look good. The problem is I am having an issue with keeping both nodes fast. If node 1 is running reports quick, then node two is very bad and vise versa. I've run hdparm -t /device on both nodes at the same time to see if I get a drop off and it certainly does. Also, the bulk of the data is being written into /folder and all nodes are reading out of that same folder at the same time. The files are basically a slat file database that records are written into via one node and read from all to be more specific. So a lot of SMALL writes (one node) and many SMALL read (all nodes). I have no clue how to optimize this or if that is possible, if one version will handle this better then another. We're on base SLES 10 and I didn't want to buy patches until I had some guidance.
