If I do pvcreate on a device that used to be part of a RAID array, the
md signature doesn't get wiped from the disk.
This is a bit less than ideal.
*** Bug 134879 has been marked as a duplicate of this bug. ***
pvcreate updated in CVS to do this.
But if --uuid or --restorefile is specified without -y, it asks the
question: these options are normally used when recovering metadata
from a backup and in cases like that you might well want the md
superblock left intact.
After running an md command, always run vgscan before running any
other LVM command.
