[ovirt-users] 回复：Re: Hosted-engine can not_switch

Fri Apr 20 10:28:49 UTC 2018

Hi,

No, this is not an error. You killed the host without moving it to
maintenance first. The engine has no way to distinguish this from
temporary network failure for example. Give it some time and the host
will move its status to one of the error states and handle the highly
available VMs on it (if fencing is properly configured).

Best regards

Martin Sivak
