NAS Cluster Tips and FAQs
The following issues could cause the
nascluster join command to fail.
You could be experiencing issues with the server timing out and not being able to process the command. If you receive the following error, rerun the command:
ERROR:: controller_commands.py:1225 Controller command 'nascluster_join' encountered error: NAS cluster operation failed: Node <ip_addr> was unable to process the nascluster_join command within 60 seconds (E-7014)
If you receive an
[Errno 1] Unknown host (E-7014) error, your NAS cluster may not be performing IP address-to-hostname resolution.
You must configure the Appliance Controller to resolve all IP addresses to hostnames, including the NAS cluster's VIP. Otherwise, the NAS nodes will not be able to recognize other nodes nor the VIP, and the NAS cluster cannot join.
You can configure IP address resolution for the NAS nodes and VIP by doing one of the following:
- Add the IP addresses for each of the NAS cluster nodes and the VIP to each NAS cluster node's /etc/hosts file.
- og in to the controller console. See Access the Appliance Controller Console.
- At the prompt, enter the following command for each node within the NAS cluster and for the NAS cluster's VIP:
net hosts add <ip_addr> <host> [<host> ...]
> net hosts add 10.10.10.8 xcellis1.example.com xcellis1
> net hosts add 10.10.10.9 xcellis2.example.com xcellis2
> net hosts add 10.10.10.10 nas-vip
- Add the IP addresses for each of the NAS cluster nodes and the VIP to DNS
