[Users] Install on USB stick fails

Hi, I've been using a 8GB USB stick to boot the oVirt Node but with only 8 GB i have no swap and less than 1 GB available for log. I bought a 16 GB but now I can't boot with this one. It gives 2 warnings: dracut Warning: Unable to process initqueue dracut Warning: /dev/mapper/live-rw does not exist Dropping to debug shell. dmesg gives the following info: EXT4-fs (sda2): mounted filessystem without journal. Opts: (null) then those warnings and the boot stops, going to a dracut shell. Any ideas? Alex
