Re: [ovirt-users] Why Node was rebooting?

[Jonathan Baecker]

I do setup power management, but because the second node if off, it's 
working not correctly. I will install now a vm on a different server, 
just for using it as a proxy.

But you think this can be the reason?

Hello community,

found out why. The engine only reports this:

[...]

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.

[ovirt-users] Why Node was rebooting?

Hello community,

While you can resize the underlying disk, but extending the root
filesystem can be a bit tricky (It can be done locally with
virt-resize, but AFAIK oVirt does not provide a UI or an API to run it
after the image had been uploaded).

We typically just add an extra disk and mount it where we need extra space.
