Description Mai Ling 2020-05-20 13:13:36 UTC

Description of problem:
I want to power off the host and not shut down the virtual machines, but instead save their state.

Version-Release number of selected component (if applicable):
iso installed from https://resources.ovirt.org/pub/ovirt-4.3/iso/ovirt-node-ng-installer/4.3.9-2020031917/el7/ovirt-node-ng-installer-4.3.9-2020031917.el7.iso

How reproducible:
Always

Steps to Reproduce:
1. suspend all running vms that have disks on the storage domain
2. storage - storage domains - domain name - data center - maintenance
3.

Actual results:
When I attempt to do this on oVirt, I get the following message:

"Error while executing action: Cannot deactivate Storage. VMs in a state other than "Down" were detected.
-Please ensure all VMs associated with this Storage Domain are stopped and in the Down state first."

Expected results:
Allow placing the domain into maintenance mode, and instead of forbidding the action only warn that there are suspended vm's on it.

Additional info:
I can do this on a regular enterprise linux libvirt host but not on oVirt.

Comment 1 Michal Skrivanek 2020-06-23 12:34:26 UTC

This request is not currently committed to 4.4.z, moving it to 4.5

Comment 3 RHEL Program Management 2021-05-24 07:43:22 UTC

The documentation text flag should only be set after 'doc text' field is provided. Please provide the documentation text and set the flag to '?' again.

Comment 5 Arik 2021-12-06 15:50:15 UTC

Restoring from hibernation might fail after moving the memory volume (seems to be related to the fact the image format could change but not sure - I got an error about image magic) - thus, set it to high

Comment 6 Arik 2021-12-06 15:54:30 UTC

high severity

Comment 8 sshmulev 2022-03-06 14:55:36 UTC

Verified.

Versions:
ovirt-engine-4.5.0-743c0a787472.211.el8ev
vdsm-4.50.0.7-1.el8ev

Steps to Reproduce:
1. Suspend all running vms that have disks on the storage domain
2. storage - storage domains - domain name - data center - maintenance
3. Activate the SD again and run the VMS


Results as expected:
The SD was set to maintance mode when the VMs using it are suspended.
There were no warnings or erros during the steps.
After activating the SD back, the VMs run without any errors.
