This is indeed what EVMS's new design does. It has user-space plugins that understand a variety of on-disk-metadata formats. There are plugins for LVM volumes, for MD RAID devices, for partitions, as well as others. The plugins communicate with the MD driver to activate MD devices, and with the device-mapper driver to activate other devices. As for whether DM and MD kernel drivers should be merged: I imagine it could be done, since DM already has support for easily adding new modules, but I don't see any overwhelming reason to merge them right now. I'm sure it will be discussed more when 2.7 comes out. For now they seem to work fine as separate drivers doing what each specializes in. All the integration issues that have been brought up can usually be dealt with in user-space. -- Kevin Corry corryk@us.ibm.com http://evms.sourceforge.net/ - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
