Hi Danishka:

Yes. I think this is related to Heartbeat.

If Heartbeat miss count reaches threshold, node will graceful recovery , which reboot the node.

Subject: [Starlingx-discuss] host system reboots with switch reboot

Hi,

I am using StarlingX release 5, dedicated storage environment.

A couple of times we noticed all nodes except the active controller rebooted after reboot of the switch.

When we purposely reboot the switch, only one storage node rebooted.

I understand the importance of the redundant switch, but is this possible with starlingX?

(Maybe an issue related to heartbeats).

Regards,

Danishka
