Recently, I used "vgdisplay", and noticed that it gives a "checksum error":

Should I be scared? What does it mean? What should I do about it? I
wouldn't like to loose the data.
If it helps, my setup looks like that:
HDD1-sda2-\
HDD2-sdb2-|__RAID-10--LVM-2
HDD3-sdc2-|
HDD4-sdd2-/
I'm running 2.6.17.8 kernel.
Hmmm... isn't it something that tells about the history of that system?
# lvmdiskscan | egrep '(sd|md)'
/dev/sda2: Checksum error
/dev/md0 [ 1.03 GB]
/dev/md1 [ 1.03 GB]
/dev/sda2 [ 371.58 GB] LVM physical volume
/dev/md2 [ 743.16 GB] LVM physical volume
/dev/sdb2 [ 371.58 GB]
/dev/sdc2 [ 371.58 GB]
/dev/sdd2 [ 371.58 GB]
/dev/md0 is RAID-1 -> swap
/dev/md1 is RAID-1 -> root filesystem
/dev/md2 is RAID-10 -> all LVM volumes
So this basically means, that LVM was set up on /dev/sda2 some time ago,
but it was never removed from there - instead, RAID-10 was set up on
that partition?
Should I do something to fix the things? What?
