Description of problem: The direct LUN is extended on a storage device. Since the Bug 1155275 "[RFE][Cinder] - Online update LUN size to the Guest after LUN resize" (https://bugzilla.redhat.com/show_bug.cgi?id=1155275) is not implemented yet, there is a recommendation to put the VM down and start again to have a new size: https://access.redhat.com/solutions/1230283 The new size is ok for VM and is seen on the hypervisor, multipathd shows the proper size as well, but still in the Admin Portal the LUN size is not updated. Version-Release number of selected component (if applicable): 4.x How reproducible: always Steps to Reproduce: 1. expand LUN on a storage device 2. put the Vm down and start again 3. check and confirm the size inside the VM, even some VG increase can be performed, check on hypervisor the LUN size in multipathd 4. check GUI and confirm it is not updated. Actual results: not updated in Admin Portal only Expected results: it is updated everywhere Additional info: The problems seems to be lack of action "refreshlun" I fixed the problem running REST API request: curl --request POST --header "Accept: application/xml" --header "Host: ${FQDN}" --header "Authorization: Bearer ${TOKEN}" --cacert /etc/pki/ovirt-engine/apache-ca.pem https://${FQDN}:443/ovirt-engine/api/disks/${LUNID}/refreshlun --header "Content-Type: application/xml" --data "<action><host id='${HOSTID}'/></action>"
Hi Olimp, In that case I think the right way is to update the docs with the last step you mentioned, isn't it?
This bug has not been marked as blocker for oVirt 4.3.0. Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.
How about adding a button to UI "refresh lun" that will run this API command per user request?
Adding an easy way to refresh LUN size sounds like a good idea, something like "Refresh Host Capabilities".

Verified via web admin and logs on version 4.4.0-0.24.master.el8ev. Refresh LUN button works and refresh the LUN disk as expected. Current bug is closed as verified - button works as it should and really refresh LUN disk and the size changed as it should. At the end of the refresh process, an UI error raised both on web admin and logs. Thus, a bug with the complete details and scenario will be open.
