Issue/Introduction

We tried to add a third cluster node but it failed when it was trying to create a vertica data directory. n this node. This is an error we received during the process

[changing ownership of /home/dradmin/: Operation not permitted']

Below is a process that we captured during the run, please advice:

If there is no datadir passed, it tries to mkdir ~username/ directory.

Resolution

We ran the following, which was successful

/opt/vertica/sbin/update_vertica --add-hosts <New_Host> -u dradmin -l /home/dradmin -L /opt/CA/IMDataRepository_vertica10/resources/vlicense.dat --rpm /opt/CA/IMDataRepository_vertica10/resources/vertica-10.1.1-20.x86_64.RHEL6.rpm -T -S default -d <Data_Folder_Path>
