I've been bitten too. I have a software RAID 10, /dev/md0, which is made
up of /dev/sd[a-d]2. /dev/md0 is the only physical volume in a volume
group. Looking at the first two sectors of /dev/sd[a-d]2, there are
indeed volume group manager labels, but this is as I would expect:
they're holding data
pvremove could not find the device in my case. It said Couldn't find
device. Check your filters? with -ff and Physical Volume /dev/sda5
note found without -ff. pvck and pvscan were of no use identifying
the label, however I knew that I had moved LVM from /dev/sda5 to
/dev/sda6 using the
Hello I known why this error appears (in my case at least), if you just
delete partition information and then recreate new ones for lvm2, it
might happen that the metadata of the deleted lvm2 partitions is still
present. The easiest way to correct this errors is to wipe out the old
metadata
OK found how to correct it :) first you need dd and hexedit.
Important you must understand this.
LVM2 stores vg metadata informations in the first 4MB of all its pvs.
After every update on a vg a new Metadata Sequence No is created.
Every pv has its own metadata Metadata Areas
So do pvscan,
I just did a fresh install (not upgrade) of Precise Server 64-bit on a
six 1.5TB RAID5 setup and I'm getting the same errors again.

I got the problem when I upgraded from Lucid to Precise (beta, a few
days before release).
When I start the computer Grub seems to run but do not show up. If I

I just did a clean install on my laptop with a simple setup of 1 VG and
2 LVs and I'm already getting the same output.

I saw this as well on a server where a forgotten PV label caused the
error message.
In my case, I sequentially checked all the partitions and raid volumes
with 'pvck' until I found the incorrectly marked one, in my case
/dev/sdh1. This partition was part of an MD array, so I failed it from

I'm seeing the same problem in 11.10 server - and none of the
suggestions around pvcreate/pv -anything seem to work.
I'm a bit reluctant to brute force things w/o a bunch more confirmation.
Help???

I don’t believe there’s any bug with GRUB here. In my case, I found
“leftover” PV headers on /dev/sda1 and /dev/sdb1 at offset 0x200 (sector

I have a fresh installation of Lucid with manually modified lvm2
partitions. I have /dev/sda1 as ext2 /boot partition, while /dev/sda5 is
a PV for the LVM2. I got the same header checksum error from all lvm2
tools and update-grub.
Doing a pvscan revealed that /dev/sda1 is an available PV member
I had this same problem. Leftover LVM metadata from some failed
installs (due to bad RAM) caused pvscan to see my /boot partition as an
extra erroneously-sized pv (~950GB instead of ~250MB). Unmounting

I discovered that the source of my problem was the way I had been
messing around with partitions during install. I had initially let it

the disk, so I

Sorry, the update-grub2 output above is not complete. Here's the
complete output:

Never mind. This appears to be a bug with LVM during install. pvscan
returns metadata errors as well. I'll create a new bug for the LVM
package.
