Hi All, how can I determine the size of each I/O? does it depend on the cluster size? block size? will it be different for each file system if each of those have different cluster size? I am just trying to understand very high I/O wait on our oracle RAC DB, where as we dont have it on another server with similar load. if the DB need 4K will it fetch only 4K? on side note, I know in ZFS it pulls the I/O of the size equal to record size (which can be co-related to clsuter size to some extent).
Regards, Pravin
