Description haiyang,dong 2014-10-23 09:03:53 UTC
Created attachment 949755 [details] attached Screenshot for console screen.jpg Description of problem: Use dd to create the image dd if=rhevh-7.0-20141006.0.el7ev.iso of=/dev/sdb But using this USB media to install rhev-h 7.0 into hosts failed.(Seen console screen.jpg) Version-Release number of selected component (if applicable): rhev-hypervisor7-7.0-20141006.0.el7ev ovirt-node-3.1.0-0.20.20141006gitc421e04.el7.noarch.rpm How reproducible: 100% Steps to Reproduce: 1. Use DD to build Flash Driver 2. Boot from usb media and select install or Re-install hypervisor Actual results: Machine is left in an unbootable state Expected results: We should get the rhevh installer console. Additional info:
Comment 1 Fabian Deutsch 2014-11-17 19:18:45 UTC
Bumping the priority, because this is one of the recommended ways (and easiest way) to create the USB boot media.
Comment 2 Ryan Barry 2014-11-17 22:51:43 UTC
Harald - This appears to be a regression of bz#1034327 on EL7. Multipath is grabbing some USB drives, and they can't be mounted. We're passing rd_NO_MULTIPATH (which looks odd on EL7 anyway), 90multipath/multipathd.sh doesn't appear to have a way to disable it on EL7. Can we get something similar to rd_NO_MULTIPATH (rd.multipath=<bool> ?) added to dracut on EL7, or is there a more canonical way to do this?
Comment 3 Ryan Barry 2014-11-18 17:48:39 UTC
Just as an aside, I also tested this against an image with the udev patch applied to EL7. Same result.
Comment 6 Fabian Deutsch 2014-11-26 10:57:19 UTC
The real problem here is multipath. We can not solve this in the scope of RHEV-H, but rely on fixes in device-mapper-multipath, see bug 1155957

Due to ycui has given test result for scratch build rhev-hypervisor7-7.0-20141201.0.iso in Comment 9, so i clean needinfo requests in here.

Test version: rhev-hypervisor7-7.0-20150112.0.el7ev ovirt-node-3.1.0-0.42.20150109gitd06b7c5.el7.noarch rhev-hypervisor6-6.6-20150112.0 ovirt-node-3.1.0-0.42.20150109gitd06b7c5.el6.noarch Test steps: 1. Use DD to build Flash Driver 2. Boot from usb media and select install or Re-install hypervisor After step2, Could get the rhevh installer console, and also reinstall the above two rhevh iso success.so changed the status into "VERIFIED".
