[Gllug] still wondering about lvm

[Adrian McMenamin]

I asked this when I recounted my tail of woe/incompetence on Sunday but
nobody answered, so here I go again...

adrian at dragoneye:~$ sudo pvscan
  Incorrect metadata area header checksum
  Incorrect metadata area header checksum
  Incorrect metadata area header checksum
  Incorrect metadata area header checksum
  PV /dev/sda5   VG Ubuntu   lvm2 [186.07 GB / 0    free]
  PV /dev/hda5   VG Ubuntu   lvm2 [76.45 GB / 460.00 MB free]
  PV /dev/hda1               lvm2 [101.76 MB]
  Total: 3 [262.62 GB] / in use: 2 [262.52 GB] / in no VG: 1 [101.76 MB]


Firstly what does Incorrect metadata area header checksum mean and how
can I fix it (google gives no simple/straight answers afaics and the STN
is much better here :))

and if /dev/hda5 is in the Ubuntu VG why doesn't df report it:

adrian at dragoneye:~$ df
