Cause

The active repository do not provide NTP package which is needed to onboard a node.

Resolution

1. Follow the steps provided in the Fedora wiki to add the EPEL repository which contains the NTP package.

# yum repolist

3. After adding the EPEL repository install NTP package by running the below command.

# yum install ntp

4. Run the below command to onboard the node.

# pf9ctl cluster prep-node
