Re: [ovirt-devel] dynamic ownership changes

Hi, I've triggered another execution [1] due to some issues I saw in the first which are not related to the patch. The success rate is 78% which is low comparing to tier1 executions with code from downstream builds (95-100% success rates) [2].

From what I could see so far, there is an issue with move and copy operations to and from Gluster domains. For example [3]. The logs are attached.
