Re: [ovirt-users] adding iSCSI storage to storagedomain not possible: checkbox disabled

There are 3 iSCSI for the setup available. When I repeat this setup with iSCSI disks, I have at least a running hosted_engine on the iSCSI lun. But I cannot add this iSCSI Lun to my initial storagedomain. In the dialog box for adding luns to Storage-domains, the check box for the lun with the hosted-engine is disabled ( shown geayed out) . How can i used this lun too? thanks for answers. Hello, I believe that the Hosted Engine requires its own dedicated LUN to function correctly, this LUN will not be part of the storage domains.

The engine is reporting trying to fence the down host, and while the host is marked non-responsive. In my scenario I am testing by yanking the power on one of the hosts, and the idrac5 that is used to fence becomes unresponsive as well as a result, which might be a contributing factor. In any case, VMs remain in a (?) state and so long as I don't click "host has been manually rebooted") they don't come online elsewhere even after a few hours.

[ovirt-users] oVirt 3.5.2 Hypervisor crash, guest VMs not migrating
Hello, I am testing guest VM migration in the event of a host crash, and I am surprised to see that guests that are selected to be highly available do not migrate when a host is forcibly turned off. I have a 2 host cluster using iSCSI for storage, and when one of the hosts, either the SPM or normal, is forcibly turned off, although the engine sees the host as non-responsive, the VMs that were running on it remain on that crashed host, and a question mark (?) appears next to them. Other than checking "highly available", is there another step that needs to be made for a VM to be restarted on a working host should the host it is running on fail?

I have set aside ambitions to use the hosted engine, I was able to restore a working engine on a seperate host, however now the engine has the former iteration of itself listed in the VMs, and I can't delete it as it is "not managed by the engine". How can I delete the former hosted-engine from the list of VMs? Thanks in advance, Ron ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] self hosted storage engine disaster recovery procedure
Hello, I am getting familiar with oVirt and using the self-hosted engine on an iSCSI SAN and so far everything seems quite impressive. I am trying to document a disaster recovery mecanism using a full OS backup as well as a engine backup as described at http://www.ovirt.org/Ovirt-engine-backup I am unclear however how to prepare the existing iSCSI LUN to receive the data restore. I am able to destroy the engine and the VMs continue to run, however I am unclear how I can free the host lock on that LUN, format it and re-install on it. Is there a howto/document I can refer to in order to do this? I am looking for info as to how I can re-install a functional engine from a backup in the case of data-corruption or any other disaster that could happen on the iSCSI LUN set aside for the engine, and a means to re-install on that LUN should the need be, without having to power down the VMs or worse, power everything down and re-install everything from scratch. How can I boot a CentOS install disk and have the previous's engine LUN as a install target, and then boot that installed OS to restore the engine backup data?
