If not, you can try checking 'yum history' and 'yum history info $ID', or if you want to try again: yum --rpmverbosity=debug update $PACKAGE (and either also '-y' and redirect to a file, or be prepared for a very long output in your terminal to copy/paste later). If you fail to get more info, 'rpm -q --scripts $PACKAGE' should should you the scripts it runs. In the case of ovirt-node-ng-update-image, the %pre script is [1]: ================================================================= local_sds=($(find / -xdev -name "__DIRECT_IO_TEST__")) if [ "$local_sds" ]; then echo "Local storage domains were found on the same filesystem as / ! Please migrate the data to a new LV before upgrading, or you will lose the VMs" echo "See: https://bugzilla.redhat.com/show_bug.cgi?id=1550205#c3" echo "Storage domains were found in:" for sd in "${local_sds[@]}"; do echo -e "\t$(dirname $sd)" done exit 1 fi ================================================================= I can see mainly two ways in which it can fail - either the 'find' command failed for whatever reason (unintendedly), or local storage domains were found (and then the failure is intended) and you should get somewhere the output - did you?

So you can/should probably try moving your storage domain to a separate filesystem. There is lots of material on ovirt.org, including many pages and many many posts to the mailing lists. I am not aware of any book-style "advanced documentation". For this particular example, to find above bug, I did this: Found the place in the source code that includes this scriptlet: https://github.com/oVirt/ovirt-node-ng/blob/master/packaging/ovirt-node-n... Search the git log for this file. You can do this in github ("History" button), but I find it much more comfortable to use 'git log -u' and search inside. This finds: https://github.com/oVirt/ovirt-node-ng/commit/a46150de468fac72224762e67e4... And this links to the bug. Best regards, -- Didi
