Issue:

Data Repository backup failed.  The error seen is vbr client subproc on xxx.xx.x.xx terminates with returncode 1. Details in vbr_v_drdata_node000x_client.log on that host.  In checking the vbr_v_drdata_node000x_client.log the following errors were seen: 

OSError: [Errno 17] File exists and Error msg: rsync: failed to connect to 172.28.129.4: Connection refused (111)

rsync error: error in socket IO (code 10) at clientserver.c(122) [sender=3.0.7]

rsync failed!

Environment:
2.x
Cause:

When checking the vbr_rsyncd.log the following error was seen

rsync: failed to create pid file <path to file>/vbr_rsyncd.pid: File exists (17)

As a result the rsync process could not grab a new pid for the backup

Resolution:

Simply remove or rename the vbr_rsyncd.pid file and rerun the backup,  It should now run to completion
