When running copycluster from production to disaster recovery site it fails with rsync error: error in socket IO (code 10) at clientserver.c(122) [sender=3.0.7] 

Inability to write to the tmp directory

2.8 clustered environment with disaster recovery

In the ini file used as the configuration file for the copycluster script there is an entry for tempDir.  Change this parameter to a different directory and make sure that dbadmin has write access to this directory on source and target environments.  The copycluster should now work

Passwordless ssh should work between all nodes in the production and disaster recovery environments
