A volume device failed. | Allow the node to continue running in a degraded state (lowered storage) | |||||
A node failed. | Repair the hardware and return it to service within 14 days if a node fails but the volume storage devices are functioning properly. All volumes are considered stale and cannot be used if a node is down for more than 14 days. Force a volume to be remounted by modifying the volume specification and adding the See Managing Volumes. | |||||

An IGMP querier must be enabled in the same network (broadcast domain) if enabled. In multicast networks, this is normally enabled on the router leading to the storage cluster, which is usually the default gateway for the nodes. See IGMP Snooping. | |||||

The network does not connect to a node configured with multiple NIC ports. | Verify the network cable is plugged into the correct NIC. Depending on the bus order and the order the kernel drivers are loaded, the network ports may not match the external labeling. | |||||
A node automatically reboots. | This issue may indicate a software problem if the node is plugged into a reliable power outlet and the hardware is functioning properly. The Swarm system includes a built-in fail safe that reboots itself if something goes wrong. Contact DataCore Support for guidance. | |||||
