OCFS, the original filesystem, only works for datafiles, logfiles, and other database data. It's currently used in serious anger by several major customers. Oracle's websites must have a list of them somewhere. We're talking many terabytes of datafiles. > Yes, I dont dispute the usefullness of OCFS for ORA_HOME (beside I think a > replicated filesystem makes more sense), I am just nor sure if anybody sane > would use it for tablespaces. OCFS2, the new filesystem, is fully general purpose. It supports all the usual stuff, is quite fast, and is what we expect folks to use for both ORACLE_HOME and datafiles in the future. Customers can, of course, use ASM or even raw devices. OCFS2 is as fast as raw devices, and far more manageable, so raw devices are probably not a choice for the future. ASM has its own management advantages, and we certainly expect customers to like it as well. But that doesn't mean people won't use OCFS2 for datafiles depending on their environment or needs. -- "The first requisite of a good citizen in this republic of ours is that he shall be able and willing to pull his weight." - Theodore Roosevelt Joel Becker Senior Member of Technical Staff Oracle E-mail: [EMAIL PROTECTED] Phone: (650) 506-8127 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
