Here is the command I run to try to install on a 3 node cluster in the beginning:
Code: Select all
/opt/vertica/sbin/install_vertica -r /tmp/vertica-ce-6.0.1-0.x86_64.RHEL5.rpm -s ip-10-0-0-50,ip-10-0-0-60,ip-10-0-0-70 -N -T
Code: Select all
/opt/vertica/sbin/update_vertica -A ip-10-0-0-60,ip-10-0-0-70 -r /tmp/vertica-ce-6.0.1-0.x86_64.RHEL5.rpm

Getting system information for cluster (this may take a while)....
Enter password for victor@10.0.0.60 (2 attempts left):
backing up admintools.conf on 10.0.0.50
NTP service not synchronized on the hosts: ['10.0.0.60', '10.0.0.70']
Check your NTP configuration for valid NTP servers.
Vertica recommends that you keep the system clock synchronized using
NTP or some other time synchronization mechanism to keep all hosts
synchronized. Time variances can cause (inconsistent) query results
when using Date/Time Functions. For instructions, see:

Info: the package 'pstack' is useful during troubleshooting. Vertica recommends this package is installed.
