This is a hairy issue.
Ugh. Tell me about it. :-(
We have a similar need (East coast replication of
our West coast filers) but I am waiting to see if something else comes along that will make this a simple issue...
Depending on how frequently your data changes, how closely you need the filers to be in sync, you might get away with something like rsync running once every so often (although, a 230 with 2M files and lots of deltas may make this a slower process) or you can try the ndmpcopy (using incrementals). Neither solution is optimal.
About 5k new files and 2k deleted files per day. Because of the nature of the data stored, files are never modified and filenames are unique across all time (that is, if a file is deleted there wil never be another file with that name). New files need to be mirrored in near-real-time, no more than a 5 minute delay. File deletions are not very significant, and could be much less than real time.
