I am trying to create a new pv/vg/+lvs setup but am getting some weird messages
pvcreate -M2 --pvmetadatacopies 2 /dev/sda1
Failed to clear hint file.
WARNING: PV /dev/sdd1 in VG Backup is using an old PV header, modify
the VG to update.
Physical volume "/dev/sda1" successfully created.
So why am I getting a message about not clearing a hint file (running s root)
and how do I modify a VG that I don't want to make any modifications to?
>From an online man page, I should have been able to use -ff to
recreate a pv over
the top of a preexisting one, but that didn't seem to work. I got:
pvcreate -ff -M2 --pvmetadatacopies 2 /dev/sda1
Failed to clear hint file.
WARNING: PV /dev/sdd1 in VG Backup is using an old PV header, modify
the VG to update.
Cannot access VG Space with system ID Ishtar with unknown local system ID.
Device /dev/sda1 excluded by a filter.

So it seems that is broken. I was able to work around that with:
dd if=/dev/zero of=/dev/sda1 bs=4096 count=1
1+0 records in
1+0 records out
4096 bytes (4.1 kB, 4.0 KiB) copied, 0.000175409 s, 23.4 MB/s
I also ran into a problem on how to tell vgcreate to use the whole pv.
That was complicated by trying to specify my hostname as a system id:
vgcreate -A y --alloc contiguous --systemid Ishtar --dataalignment
64KiB Space /dev/sda1
Failed to clear hint file.

Didn't know where the VG group ended up, which was why I needed to
redo creating the pv (vgremove didn't work):
vgremove Space

Anyway -- why does it keep failing to clear the hint file? And how
can I modify a VG without changing it (just to remove the annoying
WARNING with every command).
Thanks!
