Bug#616689: Root-on-LVM setup fails often due to timing issues

[Francesc Guasch <frankie@telecos.upc.edu>]

Hi. I too stumbled with this bug. In my experience I have to
manually type vgchange -a y every time it boots. Then CTRl-D.

I tried adding the suggestions to grub, but it didn't work.
Maybe I just missed something ?

I modified:

    /etc/default/grub

and added this:

    GRUB_CMDLINE_LINUX="scsi_mod.scan=sync"

I also tried this:

    GRUB_CMDLINE_LINUX="scsi_mod.scan=sync rootdelay=20"


then I run update-grub. I checked the grub command line when
booting and the options were there.
