Question

rsync on two servers Master-Master upload and delete problem

Asked by: cimmer

I have two servers clustered and synchronized with rsync, both these servers are set to be master and slave to one another i.e. Server1 is a master as well as a slave to Server2 and vice versa, now when a file is created on one server it is comfortably replicated on the other, but when i delete a file from one, the other server blindly copies that file back to the first server to synchronize it with itself, can someone help me out with this situation, or recommend me some other tool other than rsync to synchronize the servers for deletes too.

Do you have the rsync process running on both servers?

 

by: LunarNRGPosted on 2009-08-12 at 20:58:33ID: 25085353

You haven't mentioned how you are using rsync, ie. command line arguments. I assume you already know about --delete, and your problems are due to a timing issue. Nonetheless, I tend to think this use of rsync is fraught with peril.

You may want to look at unison[1] instead, which should be able to better handle the bi-directional mirroring -- or perhaps ha[2].
