Thanks for the tip. I will then upgrade to 4.4. By the way, how about the progress of the support of Ceph storage for Ovirt? Proxmox has a very good successful story of integrating Ceph, and we hope Ovirt would soon catch up. best regards, samuel Do Right Thing (做正确的事) / Pursue Excellence (追求卓越) / Help Others Succeed (成就他人) From: Sandro Bonazzola Date: 2021-10-20 09:16 To: Xiaoyu Hu CC: oVirt Users Subject: [ovirt-users] Re: Ovirt VM started with the most recent snapshot with the current disk missing Il giorno dom 17 ott 2021 alle ore 13:57 Xiaoyu Hu <samuel.xhu(a)gmail.com&gt; ha scritto: Dear Ovirt folks, I am faced with a very strange situation with Ovirt 4.3. A virtual machine has two snapshots and a working disk, with the former two snapshots being read only and the working one read-write. After an unplanned power outage, a virtual machine can only be started with the recent snapshot, and the actual working disk is missing in the Ovirt UI. I can see the disk still exists in the backend storage, but it seems not Ovirt does not know it. Thus the VM lose the recent data on the missing disk. Does any one know whether this is a known bug in Ovirt 4.3, or is there a method to resotre the missing working disk back to the virtuanl machine? Otherwise i am faced with a terrible data loss issue on Ovirt Hi, oVirt 4.3 reached the end of life a long time ago. I would recommend upgrading to oVirt 4.4 as soon as practical. best regards, Samuel _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/N7JVXAU5MLA... -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA sbonazzo(a)redhat.com Red Hat respects your work life balance.
