Re: geo-replication command rsync returned with 3

[Dietmar Putz <dietmar.putz@xxxxxxxxx>]

Hi Kotresh,

thanks for your response...

i have made further tests based on ubuntu 16.04.3 (latest upgrades) and gfs 3.12.5 with following rsync version :

1. ii  rsync                              3.1.1-3ubuntu1
2. ii  rsync                              3.1.1-3ubuntu1.2
3. ii  rsync                              3.1.2-2ubuntu0.1

in each test all nodes had the same rsync version installed. all tests failed with the below shown error.
then i started a test with the same setup. this time upgrades for ubuntu 16.04.3 were disabled.
again i have tested the above shown rsync versions on all nodes. the geo replication works fine in any case.
then i have installed  3.1.1-3ubuntu1.2 on each node as it is installed with latest ubuntu upgrade.
afterwards i have just upgraded all slave nodes with the latest ubuntu upgrades, reboot...the geo-replication still works fine.
after upgrade and reboot of the master nodes with the latest ubuntu upgrades the below shown error appeared again... geo rep is broken.

i believe one of the below shown packages caused the error because directly after upgrade of these packages the error appeared
on the corresponding master node....
anyone else who has experienced this issue...?
any help would be appreciated.

best regards
Dietmar

It is clear that rsync is failing. Are the rsync versions on all masters and slave nodes same?

I have seen that has caused problems sometimes.

Hi all,

i have made some tests on the latest Ubuntu 16.04.3 server image. Upgrades were disabled...
the configuration was always the same...a distributed replicated volume on 4 VM's with geo-replication to a dist. repl .volume on 4 VM's.
i started with 3.7.20, upgrade to 3.8.15, to 3.10.9 to 3.12.5. After each upgrade i have tested the geo-replication which worked well anytime.
then i have made an update / upgrade on the first master node. directly after upgrade the below shown error appeared on that node.
after upgrade on the second master node the error appeared there also... geo replication is faulty. 

this error affects gfs 3.7.20, 3.8.15, 3.10.9 and 3.12.5 on Ubuntu 16.04.3
in one test i have updated rsync from 3.1.1 to 3.1.2 but with no effect.

does anyone else experienced this behavior...any idea ?

best regards
Dietmar
