Hello community,

yesterday evening one of our nodes was rebooted, but I have not found 
out why. The engine only reports this:

        24.11.2017 22:01:43 Storage Pool Manager runs on Host onode-1
        (Address: onode-1.worknet.lan).
        24.11.2017 21:58:50 Failed to verify Host onode-1 power management.
        24.11.2017 21:58:50 Status of host onode-1 was set to Up.
        24.11.2017 21:58:41 Successfully refreshed the capabilities of
        host onode-1.
        24.11.2017 21:58:37 VDSM onode-1 command GetCapabilitiesVDS
        failed: Client close
        24.11.2017 21:58:37 VDSM onode-1 command
        HSMGetAllTasksStatusesVDS failed: Not SPM: ()
        24.11.2017 21:58:22 Host onode-1 is rebooting.
        24.11.2017 21:58:22 Kdump flow is not in progress on host onode-1.
        24.11.2017 21:57:51 Host onode-1 is non responsive.
        24.11.2017 21:57:51 VM playout was set to the Unknown status.
        24.11.2017 21:57:51 VM gogs was set to the Unknown status.
        24.11.2017 21:57:51 VM Windows2008 was set to the Unknown status.
        [...]

There is no crash report, and no relevant errors in dmesg.

Does the engine send a reboot command to the node, when it gets no 
responds? Is there any other way to found out why the node was 
rebooting? The node hangs on a usv and all other servers was running well...

In the time, when the reboot was happen, I had a bigger video 
compression job in one of the VMs, so maybe the CPUs got a bit stressed, 
but they are not over committed.

Regards

Jonathan
