[ovirt-users] Leaving maintenace mode

[Stefano Danzi]

Hi!

I have a testing oVirt installation with only one host and running self 
hosted engine.

If I put host in global maintenance mode:

  hosted-engine  --set-maintenance --mode=global

then ssh into self hosted engine VM, shoutdown VM using 'init 0', when
I run on the host:

hosted-engine  --set-maintenance --mode=none

I have:

Traceback (most recent call last):

This because the host has the iso domain nfs export mounted but the self 
hosted engine VM is not running, I think...
So I have to reboot the host before change the maintenance mode.
