Overall it's sound and will definitely find its customers, but use cases in the proposal could be a bit more detailed so that project goals are clear right away. Few points to mention (my apologies if these have been already discussed on this thread): 1. What is the primary use case - 'single shot' file-system migration (customer is upgrading box A to Box B and wants to move data once), or recurrent (policy-based) migration typically found in multi-tier set-up (so that data migrates down on-line/near-line/off-line path as, for example, it gets colder)? 2. As described, DMM appears to assume symmetric approach with manager active at both source and target. Asymmetric one, with target mounting source over NFS/CIFS (and no DMM at source), extends the reach to frequent use case of migrating data between heterogeneous sources. 3. Do you anticipate to use NFSv4 features supporting file-system migration (client-side redirection based on server's 'file system moved' response) or target activation is expected to be achieved by other means (e.g. manually)?
