Re: Way to create large block size under LINUX for ORACLE dataabase??

The matrix above is out of date. At least for Ext3Filesystem, single file can be much larger than 2gb. And solaris should only support 4k/8k blocksize?(even for vxfs).

Bigger blocksize doesnot always means better performance. And if you really want big block size, you can always go with raw device. Which does not have such a concept.
