When you update rsync on the head node also update it on the image.
copy the rpm into the image directory (probably something like
/var/lib/systemimager/images/oscarimage/tmp)
chroot /var/lib/systemimager/images/oscarimage
install the rpm from /tmp in the new environment
exit the chroot and try imaging the nodes
I think there are some scripts to do this as well, but I haven't gotten
around to learning how to use them yet :)

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.
Cheers,
Ivan
