How does one copy large (20TB) amounts of data from one cluster to another?
Assuming that each node in the cluster can only do about 30MB/sec
between clusters and i want to preserve the uid/gid/timestamps, etc
If the clusters are co-lo I wouldn't copy I would use shared storage. If
they are not co-located I would use patience.
Seriously though, for a one time copy, I would consider copying to an
external system and then physically moving that system. To do this and
preserve ownerships you will need to duplicate accounts and groups.
