Seems a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1334726 I'm going to test the scenario with labels and update in case this still happens. *** This bug has been marked as a duplicate of bug 1334726 *** |
Created attachment 1269362 [details] engine.log, vdsm.log, journalctl output guest vm. Description of problem: This probably has to be moved to the RHEL PPC but I was wondering if you guys can take a look in case I'm missing something. So I have a clone VM with a boot OS and 6 other virtio disks (3 thin, 3 prealloc 1G) with a FS each. I create a file on each, add a snapshot and that 3 times. After I remove middle snapshot, preview the last snapshot, and the vm fails to start. Version-Release number of selected component (if applicable): rhevm-4.1.1.8-0.1.el7.noarch guest agent: Linux localhost.localdomain 3.10.0-514.el7.ppc64le #1 SMP Wed Oct 19 11:27:06 EDT 2016 ppc64le ppc64le ppc64le GNU/Linux How reproducible: 100% Steps to Reproduce: 1. Clone a vm from a template. 2. Attach, activate, and create an ext4 fs for 6 virtio disks (3 thin, 3 prealloc) 3. Mount the fs. 4. Create a file in all the disks and take a snapshot of all disks (x 3) 5. Remove the middle snapshot. 6. Preview last snapshot. Actual results: VM fails to start Expected results: VM starts, all files are there.
