Fabian, did this include the reverted mount_live changes? Chaofeng: I won't be able to look at this until next week. Can you attach an rdsosreport in the meantime? Yes. 0928 contains ovirt-node-3.3.0-0.10.20150928gite7ee3f1.el7ev which is everything up to the git tag ovirt-node-3.3.0-0.10 Also, is this reproducible with other upgrade methods? There were some other bugs about upgrading via the TUI, but none of those dropped to dracut, and the patch which resolves should be part of this build. If you try to upgrade via the TUI, does it also drop to dracut? Hi Ryan, Attached rdsosreport.txt. I also test TUI and cmd upgrade, both of two upgrade scenarios are successful, after upgrade the system can boot up correctly. Created attachment 1081546 [details]

This is caused by the new initramfs generation. It works as expected in TUI (and probably PXE) upgrades because it's running the new kernel. It does not work from RHEV-M, because RHEV-M generates an initrd for the kernel which is running when upgraded (7.1), and not the newly-installed kernel. multipathd doesn't start, because dm-multipath can't be loaded. Actually, no modules can be loaded, because they're all for the wrong kernel version. I'm investigating a fix, and should have one out today or tomorrow. Verified on the rhev-hypervisor7-7.2-20151104 build. Version-Release number of selected component (if applicable): ovirt-node-3.6.0-0.20.20151103git3d3779a.el7ev.noarch rhev-hypervisor7-7.2-20151104.0.iso Steps: 1. Install rhev-hypervisor7-7.1-20151015.0.iso and register to RHEV-M 3.5.6.2-0.1.el6ev. 2. On RHEV-M web portal, set rhev-hypervisor7-7.1-20151015 to maintenance, then the upgrade to rhev-hypervisor7-7.2-20151104.0.iso. Result: Upgrade successful, rhevh status is up on RHEV-M portal.
