The output of this command looks promising: # pvscan -u Incorrect metadata area header checksum PV /dev/md2 with UUID 0iEU34-XNSd-vNpu-G3uW-2F1v-wEy9-Bw199N VG volgrp3 lvm2 [931.51 GiB / 11.51 GiB free] PV /dev/md0 with UUID Lb3KzG-9tZM-5MbQ-1DUa-5ErW-DYf1-NqvMJW VG volgrp1 lvm2 [697.70 GiB / 5.44 GiB free] PV /dev/md1 with UUID uWDdXr-8fRw-aJDG-SzdQ- yeIl-6dsv-28vJYs lvm2 [697.70 GiB] Total: 3 [2.27 TiB] / in use: 2 [1.59 TiB] / in no VG: 1 [697.70 GiB] That last UUID is still associated with a bunch of volgrp2 objects in my current LVM configuration (the old LVM volume on /dev/md1), even though pvscan currently doesn't recognize it as such.
