[gpfsug-discuss] Migrating billions of files?

[Yaron Daniel]

Hi

What permissions you have ? Do u have only Posix , or also SMB attributes 
?

If only posix attributes you can do the following:

- rsync (which will work on different filesets/directories in parallel.
- AFM (but in case you need rollback - it will be problematic) 

 
Regards

I?m looking at migration 3-4 Billion files, maybe 3PB of data between GPFS 
clusters. Most of the files are small - 60% 8K or less. Ideally I?d like 
to copy at least 15-20M files per day - ideally 50M.
 
Any thoughts on how achievable this is? Or what to use? Either with AFM, 
mpifileutils, rsync.. other? Many of these files would be in 4k inodes. 
Destination is ESS.
