Subject: [ovirt-users] Recovering hosted-engine

Hi

A couple of questions about hosted-engin= =3D e recovery.
Part way through this URL, in the section "Workflow f= =3D or Restoring the Self-Hosted Engine Environment"=3DC2=3DA0
http://www.ovirt.org/documentation= =3D /self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environm= =3D ent/
it looks like once the hosted-engine is recovered on Hos= =3D t 1, the VMs on Host 2 and 3 will be running, but not accessible to the rec= =3D overed Hosted Engine.=3DC2=3DA0
Is that correct?
If so,= how =3D to you remove host 2 and host 3 from the environment, then add back in aga= =3D in while keeping the VMs running?

Host 2=3DC2= =3DA0a=3D nd=3DC2=3DA0Host 3= =3D=3DC2=3DA0are not recoverable in their current state. These hosts ne= ed=3D to be removed from the environment, and then added again to the environmen= t =3D using the hosted-engine deployment script. For more information on these a= =3D ctions, see the Removing Non-Operational Hosts from a Restored Self-Hosted= =3D Engine Environment section below and=3DC2=3DA0Chapter 7: Installing = =3D Additional Hosts to a Self-Hosted Environment.

BTW: The link referring to chapter 7 is broken.=3DC2=3DA0=

VMs? I'd like to clarify that "recovery" can span a large spectrum of flows, from a trivial "I did some change to the engine database that broke stuff and I want to restore a backup I took prior to this change" to a full system restoration including purchasing and deploying new (perhaps different) hosts/network/storage hardware, including many other flows in between. So when you plan for recovery, you should define very well what flows you plan to handle, and how you handle each. The linked procedure correctly says it's "providing an example". > > Kind regards > > > Andrew > > > > ------ Original Message ------ > From: "Andrew Dent" > To: "users" > Sent: 2/07/2017 2:22:16 PM > Subject: [ovirt-users] Recovering hosted-engine > > Hi > > A couple of questions about hosted-engine recovery. > Part way through this URL, in the section "Workflow for Restoring the > Self-Hosted Engine Environment" > http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restor= ing_an_EL-Based_Self-Hosted_Environment/ > it looks like once the hosted-engine is recovered on Host 1, the VMs on H= ost > 2 and 3 will be running, but not accessible to the recovered Hosted Engin= e. > Is that correct? I am pretty certain that the procedure assumed that all hosts need restorat= ion, not that some are still up-and-running. > If so, how to you remove host 2 and host 3 from the environment, then add > back in again while keeping the VMs running? That's a good question. Please try to describe the exact flow you have in mind.

You are right. The link in the bottom of the page seems working. Now pushed [1] to fix. Thanks for the report!
