Created attachment 940428 [details] output of livecd-iso-to-disk Description of problem: livecd-iso-to-disk fails to write iso to disk. Firstly I clear usb (with dd) then I run: livecd-iso-to-disk --format --reset-mbr Fedora-Server-netinst-i386-21_Alpha.iso /dev/sdb this ends up with following error: basename: missing operand I add 'set -v' and 'set -x' to script and this is what happens right before it fails: + '[' -e /sys//devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3:1.0/host7/target7:0:0/7:0:0:0/block/sdb/sdb1/device ']' +++ readlink -f /sys//devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3:1.0/host7/target7:0:0/7:0:0:0/block/sdb/sdb1/../ ++ basename basename: missing operand You can find the whole output attached. Version-Release number of selected component (if applicable): livecd-tools-21.2-4.fc21.x86_64 How reproducible: always after with clean usb disk Steps to Reproduce: 1. clear usb (with gnome-disks or dd) 2. run 'livecd-iso-to-disk --format --reset-mbr SOME_ISO.iso /dev/sdb' Actual results: basename don't get operand Expected results: It should continue Additional info: When I put sleep 10 right before the line where this happens it continues (but fails sometime later)
Just a note, the same error occurs also with Workstation Live i686, not just Server netinst i386 (both Alpha RC1).
This is probably a Beta blocker for the same reason I proposed bug 1144040: https://fedoraproject.org/wiki/Fedora_21_Beta_Release_Criteria#Release-blocking_images_must_boot "Release-blocking live and dedicated installer images must boot when written to optical media of an appropriate size (if applicable) and when written to a USB stick with any of the officially supported methods." I guess it applies to F21 host (converting the image) as well. One more note, the fact that adding "sleep" to the script changes behavior, it seems that this is a race condition that became very frequent lately, probably triggered by some update. That means, unfortunately, that not everyone has to be able to observe this issue, or not that frequently.
I did a reboot without rhgb or quiet and the last entry was: reboot machine restart The other thing I saw today was a hang with a non-live reboot on the same machine. This was also F21, but with a 3.17 kernel.There was not a systemd update betwwen the boot and reboot. (Systemd updates often cause reboot hangs.) There wasn't any log of the shutdown. The mouse pointer froze imediately and I had to power off before I could reboot. That is different than what I was seeing with the live image reboot hangs. So this might be something separate.
Ignore my last comment, that was supposed to be for another livecd-tools bug.
I tried it again today on various machines and it doesn't happen now. It seems that it is related to my problems with microcod-ctl (or maybe it was hardware problem). I'm closing this bug. If I will reproduce this again I will open it again.
