rsync - Feb 2013 - rsync 3.0.9 compile --copy-devices --write-devices not working

Hi Folks,

i recently try to use rsync on devices. The goal is to sync two logical
volumes without copy the whole.

According to

http://gitweb.samba.org/?p=rsync-patches.git;a=tree

write-devices.diff
copy-devices.diff

should do the job.

I downloaded

https://rsync.samba.org/ftp/rsync/rsync-3.0.9.tar.gz

and tried to apply the two .diff from your gitweb

resulting in:

write-devices.diff:

Ok, not working, while i wonder why there are in the git patches to
download which can not be applied to the source code ?!


Anyway, i tried not to give up.

And found

https://rsync.samba.org/ftp/rsync/rsync-patches-3.0.9.tar.gz

In there, i found copy-devices.diff, which could be applied successfully :-)
A write-devices.diff is missing :(

I compilied it, and run it. The result:

root at source:/usr/src/rsync# rsync -e ssh --copy-devices
/dev/storage1/snap-cdimages root at destination:/dev/storage1/cdimages
root at destination's password:
skipping non-regular file "snap-cdimages"


##########

So in the very end, one modul not being able to compile at all.

The other modul just seems not to work.

Does anyone have some hint how to make it working ? Also running an
older version of rsync would be ok.

Or also advices about other solutions on how to sync two devices without
need to copy the entire data again if just a part was changed.

Thank you very much

Greetings
Oliver

Mh, apparently rsync-patches-$release.tar.gz and rsync-patches.git are not in
sync for some reason.

I found that there are patches in git which are missing in tar and vice versa. 

I would have thought that patches.tar.gz is a copy of the .git contents at
relase date (For example, drop-cache.diff is in the tar, but not in current git)
