Why is my rsync command not working between Openshift gears?

Question

I'm trying - like many other people - to rsync data between gears of a scalable app.

I have created a minutely cron file that gets executed and can get and parse a list of gears. It can then determine which ones are NOT the local gear and then tries to rsync the app-root/data folder of each gear to the $OPENSHIFT_DATA_DIR (should be on local gear)...

The first part works, but the rsync command fails with:

rsync: connection unexpectedly closed (0 bytes received so far) [receiver]

I have tried about a dozen variants of

rsync -avz -e "ssh -i ${OPENSHIFT_DATA_DIR}.ssh/id_rsa" [email protected]:app-root/data/test/ ${OPENSHIFT_DATA_DIR}test

$targetgear is a variable from parsing the list of gears - it's the long string of "stuff" in the gear name... the script loops through the csv list provided by haproxy and correctly writes what it finds to a log file, so I know it's getting at least that far...

The id_rsa file exists and has been added to the account in the web control panel.

Any help or pointers would be greatly appreciated. I have combed pages and pages of forum posts and documentation on rsync and ssh, but can't seem to get around it...

Thanks in advance.

THANK YOU RAUL!!! Ok... The problem was the url for the target gear - I needed the long string of gunk TWICE:

$targetgear@$targetgear-user.rhcloud.com ...

and not

The app name prefix in the url is replaced by the gear ID.
