140502-POA-87328-epel-repo-at-lb [WebCluster]: Some NG Load Balancers with default scripts don't have epel repo configured and ucarp rpm package installed. You should: add epel yum repo to following nodes. cluster id:60 lb ip:10.4.4.10
Precheck script tried to login to load balancer 10.4.4.10 as user root using private key on management node /root/.ssh/id_rsa_lb and verify if rpm ucarp is installed or epel yum repository is configured.
Load balancers are not registered in POA as service nodes and they are managed using ssh with private key /root/.ssh/id_rsa_lb.
- Public key from management node /root/.ssh/id_rsa_lb.pub should be added to the affected load balancer /root/.ssh/authorized_keys2 file.
- sshd should allow root login by key. In sshd configuration file /etc/ssh/sshd_config option PermitRootLogin should be yes (default) or without-password.
Access could be verified manually from management node:
ssh -i /root/.ssh/id_rsa_lb -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null email@example.com
