Hello,
I followed the user's guide recommendation of 4K block size and 128K
cluster size. I have 8 32GB OCFS2 filesystems mounted on two nodes.
The DBA has created a large tablespace with 4GB data files on each
filesystem.
The performance is only getting 3,400 IO/sec read/write combined. If I
re-use the LUNs and give the DBA 4GB raw partitions, he can get over
7,000 IO/sec read/write combined (single-node) and over 11,000 IO/sec on
two nodes.
What's my next step to improve performance of OCFS2? Since the DBA is
using 4GB datafiles, should I increase the cluster size to the max 1MB?
Thanks for any hints.
/Brian/
