The gpssh process is hanging and not providing an interactive shell. You will still can run commands like gpssh -f host_file uname, but you will not get a shell. In this case the .bashrc file on the segment node is configured with some variables that interfere with this operation: export PS1="[`whoami`@mdwt:$PGPORT:$PGDATABASE]$ " export PROMPT_COMMAND='export PS1="[`whoami`@mdwt:$PGPORT:$PGDATABASE]$ "' Remove the above variables and things should work properly. |
