Liron, can you take a look please? Nikolai, the issue here seems to be a failure to write to the leases file on the domain, it's under the dom_md folder (called leases). can you check it?

I think it's connected to newer version of qemu-kvm, which should be different than I used, please check if the provided one is good one. Regarding "dom_md", that's a real problem, I don't have the setup anymore, so please reproduce the bug using described scenario on your environment and get the log, I'm sorry to give you such an answer, but don't have the resources for this:(. The issue shouldn't be related to qemu-kvm, as the failure is in sanlock.init_resource. I ran similar scenario on my env and it worked fine, as i don't have access to your storage i can't know what was the underlying issue. closing this for now on INSUFFICIENT DATA.

Latest attached files connected to https://bugzilla.redhat.com/show_bug.cgi?id=1132529. Original bug environment have to be established in order to get bug reproduced, on R&D or QE side. Nikolai, From the initial testing that we have done the issue hasn't reproduced. If you manage to reproduce it please write it down here. Right now we don't have enough info to continue to that bug. leaving it open for now till it'll be reproduced. bug 1132529 has nothing to do with this bug. We've tried to reproduce THIS bug on several envs, both in dev and in storage QE, and failed. If you can reproduce it, please do so, attach updated logs, and add exact steps to reproduce. Worked for me as well on latest components: vdsm-4.16.2-1.gite8cba75.el7.x86_64 sanlock-3.1.0-2.el7.x86_64 qemu-kvm-rhev-1.5.3-60.el7_0.2.x86_64 ovirt-engine-3.5.0-0.0.master.20140821064931.gitb794d66.el6.noarch |
Created attachment 927942 [details] logs from both hosts Description of problem: Failed to create a simple snapshot including memory from guest running VM3 with RHEL7 as a guest, over RHEL7 host. Version-Release number of selected component (if applicable): vdsm-4.16.1-4.gitb2bf270.el7.x86_64 sanlock-3.1.0-2.el7.x86_64 qemu-kvm-1.5.3-60.el7_0.5.x86_64 libvirt-1.1.1-29.el7_0.1.x86_64 qemu-kvm-common-1.5.3-60.el7_0.5.x86_64 How reproducible: 100% Steps to Reproduce: 1.Create VM with 1 bootable disk from NFS SD with installed RHEL7 on it and within RHEL7 3.5 HE environment containing one host for HE, while second host should be added to HE from WEBUI not as HA, just as additional host to the host cluster (HA not running on it). 2.Run VM over host that is not running HE and not a part of HA. 3.Try creating snapshot... Actual results: Snapshot fails with error " Failed to complete snapshot 'snmpshwithmem' creation for VM 'VM3' " Expected results: Snapshot should succeed. Additional info: Logs from two hosts provided.
