LVM is a powerful, enterprise tool that uses Linux's Devicemapper subsystem to provide a wealth of possibilities for organizing and optimizing attached block storage. But, with power comes complexity. Dealing with errors, or even just making changes may cause infrequent users of the LVM tools to feel uneasy. Froyo provides a more managed storage solution -- feed it disks, and it gives you "a filesystem where your data is safe forever that never runs out of space".
Of course, under the covers are familiar technologies -- devicemapper and XFS, with Froyo pulling the strings. Andy Grover will talk about the development and implementation of Froyo, how it manages seamless online reconfiguration and monitoring of its member disks, and look forward to possible future improvements that leverage existing DM capabilities in new ways.
