I don't think I _ever_ said it couldn't be done. In fact, the Ext3 support is now up to 17.6TB (16TiB) now. But is there any guarantee that volume will work if moved to another set of hardware, kernels, etc...??? As I said, I _never_ create Ext3 filesystems greater than 1TB for this reason. 1TB is the "common denominator" when it comes to Ext3. > Perhaps the bugs you're hitting are in the FC driver layer? There's all sorts of "requirements" for Ext3 sizes above 1TB, and assuming it will always work is an assumption I'm not willing to make with my client's data. But that's just me. I have to see repeatable results, and I have not with Ext3 above 1TB. -- Bryan P.S. Red Hat's going to wake up sooner or later and realize it's just as Sun said, they have not addressed the enterprise filesystem issue. I'm sure SGI and the XFS team would be more than happy to see some engagement from Red Hat on this matter -- and have wished for years now -- and the said thing is that it would _help_ Red Hat's future. XFS is the only option -- ReiserFS and JFS have interface/compatibility issues that are "show stoppers" for Red Hat. XFS has not, and the only issues are newer kernel/distribution developments that just need to be addressed at a distro-level. -- Bryan J.
