I'd like to propose a project that will investigate support for Device Mapper facility [0], similar (or even compatible) to Linux device-mapper facility[1].
While OpenSolaris comes with state of the art native storage features and capabilities it lacks interoperability with technologies used in other systems like Linux. For example Linux LVM2 framework[2] is very popular disk management facility used by default by numerous Linux distributions. LVM2 uses device-mapper[1] as a kernel low-level engine and has a set user-land utilities to manage its entities. LVM2 interoperability can be very nice supplement to the ext[23] file system support project suggested recently to this community. Generic device mapper facility in Solaris will create a foundation for providing other layers both for interoperability purposes (LVM2, etc) and other Solaris native uses (think lofi being just a wrapper around device mapper for example).
