+++ This bug is a downstream clone. The original bug is: +++ +++ bug 1488542 +++ ====================================================================== Description of problem: During live snapshot deletion on vm holding 5 disks. We see that the merge is sucessfull for 4 disks and 1 fails on engine side but completes on host side. According to vdsm.log it appears that when a Live Merge for one disk was being performed, a No such drive error was reported while checking the block job after the pivot had completed. The volume that caused this was the volume that was just pivoted from, i.e. the original active volume. However this merge completed sucessfully but caused other disk merge operation to fail on engine side but complete on host side. The images are marged illegal on rhevm database and lv's remain unremoved on Host. Issue seems similar to the bug https://bugzilla.redhat.com/show_bug.cgi?id=1447437. Opening this new bug to check further if this new bug or regression. Version-Release number of selected component (if applicable): rhevm-4.1.4.2-0.1.el7.noarch libvirt-daemon-2.0.0-10.el7_3.9.x86_64 vdsm-4.19.20-1.el7ev.x86_64 How reproducible: No Steps to Reproduce: 1. 2. 3. Actual results: "No such drive" LookupErrors occurred while checking a block job after the pivot had completed, causing the engine to "fail" merges for two other disk Expected results: Merge should complete without any errors.
