if i read description of CDMS it is used to migrate data from external NFS and CIFS servers, not to perform internal migration. Look at server_archive, it's actually pretty fast.
Dear All,  I have seen discussions here how to move filesystems back and forth from console changing mounts and using emcopy etc..  What I am after is to use the built in UI data migration interface to migrate data from FS to FS within the same pool/data_mover. Basically I'm trying to move data off of 2TB thin luns onto many 512GB thick ones to improve overall performance. I could use an external NFS box by mounting the shares and rsync them but I've noticed I can mount the share on the data_mover itself and create a migration filesystem.   Would this scenario be a lot faster (internally) than mounting the shares remotely and rsync? I have about 3TB worth of data to move.  Any advice appreciated!  Regards
