LVM on RAID with preserve_reinstall

[Erik Meitner]

What is the status of using preserve_reinstall on LVM volumes that use 
md devices for their PV?

When flag_initial=1 and I am re-installing the machine(a test VM in this 
case) FAI does not activate the md devices so the LVM volumes are never 
found. FAI reports "Can't preserve /dev/vg_data/data because it does not 
exist"

For some reason FAI is not activating the raid devices

Thanks.
