Could be the same or same causes as https://bugzilla.redhat.com/show_bug.cgi?id=1410428 thought the errors are different. Severity? Regression? This bug might be the same as https://bugzilla.redhat.com/show_bug.cgi?id=1408977 (In reply to Raz Tamir from comment #3) > This bug might be the same as > https://bugzilla.redhat.com/show_bug.cgi?id=1408977 This is a different issue than BZ 1408977. BZ 1408977 happens when cloning a VM from a template and it fails at prepareMerge step. This one occurs when the distance (number of volumes) between the merged volume and the leaf is greater than one. As an example, consider this chain: base -> s1 -> s2 -> s3 -> leaf. When merging base, s1 or s2, we will hit this issue. However, merging s3 works fine. This BZ fails at finalizeMerge step. Verified on ovirt-engine-4.1.0.3-0.0.master.20170122091652.gitc6fc2c2.el7.centos Followed the steps to reproduce and the snapshot removal works |
Created attachment 1237631 [details] vdsm and engine logs Description of problem: Fails to cold merge a in-between snapshot Version-Release number of selected component (if applicable): ovirt-engine-4.1.0-0.3.beta2.el7.noarch vdsm-4.19.1-1.el7ev.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create a VM with multiple disks (1 boot + 4 disks) on an ISCSI Domain. 2. Do it 3 times: Start the vm, write a file on the boot disk, shutdown the vm and create a snapshot (snap #0, snap #1, snap #2) 3. Remove the middle snapshot (snap #1) Actual results: Operation remove snapshot fails Expected results: Operation succeeds and the snapshot is removed. Additional info: This works in last 4.0.X build. 2017-01-05 12:34:03,843+02 INFO [org.ovirt.engine.core.bll.tasks.SPMAsyncTask] (DefaultQuartz Scheduler10) [54dd3262] Task id '203b21e4-ce7e-4903-9c12-f7736c6a76f4' is in pre-polling peri od and should not be polled.
