Yes I did, to no avail. In fact, networking works perfectly well as far as anything else but rsync is concerned. I ran rsync manually from client (slave node) side with -vvv option and specifying just one oscarimage subdirectory to simplify things a bit. It starts the protocol, successfully obtains the list of remote files, creates proper sym/hard links in the target (local) directory and then hangs on phase_1 (AFAIK that's when the actual file copying should start). It looks like a bug in rsync and searching through rsync mailing list I can see several similar bugs submitted. They are all unconfirmed because of highly random and unreproducible nature. I found that in my case the only cure is a complete fresh reinstall of the server node OS+OSCAR, including disk reformatting (!). After that, I sometimes am able to make image push work once or twice. Then it fails again and after that nothing can make it push a single byte anymore. Weird, isn't it? I'll try to upgrade rsync on the server and see if it helps.
