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.
