Filesystems that have zero awareness of the storage geometry have poor performance on striped RAID devices. XFS has excellent performance on striped RAID specifically due to this awareness. Now you describe this strength as a weakness due to a volume portability corner case no SA in his right mind would attempt. The proper way to do this is to perform an xfsdump of the filesystem to a file, create a new XFS with the proper stripe geometry in the new storage location (which takes all of 1 second BTW), then xfsrestore the dump file. And now you will say "Yes, but..." -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
