[gpfsug-discuss] GPFS cpoying huge batches of files from one stgpool to another- how do you do it?

  Just wondering how other people go about copying loads of files in a many, many deep directory path from one file system to another.  Assume filenames are full UNICODE and can contain almost any character.

It has me wishing GPFS had a COPY FROM support as well as a MIGRATE FROM function for policies.
Surely that would be possible...?

Ways I can think of are:

-          Multiple 'scripted intelligent' rsync threads

-          Creating a policy to generate a file list to pass N batched files to N nodes to exec (again rsync?)

-          Barry Evans suggested via AFM.  Though out file system needs to be upgraded before we could try this.

Rsync handles UNICODE names well. tar, though faster for the first pass does not.

Any ideas?
