I'm worried that using mdadm_udev is just hiding errors related to mdadm assembling the arrays. It's not even clear to me how the arrays are assembled with mdadm_udev.

I also find it odd that the ERROR line above contains an empty string made of two apostrophes, rather than the path to the root file system (i.e. the root logical volume).

The lvm2 hook does the following after printing "Activating logical volumes..."

[ -d /etc/lvm ] && /sbin/lvm vgscan
eval /sbin/lvm vgchange --sysinit -a y $LVMQUIET
