Trying to enlarge a LV after adding a new PV to the VG.

I get an horrible string of messages:

lvextend -L+400M /dev/vg1/lvusr
Extending logical volume lvusr to 3.09GB
Inconsistent length 66 71
PV segment pe_alloc_count mismatch: 1436 != 1520
PV segment VG free_count mismatch: 1570 != 1486
Internal error: PV segments corrupted in vg1

Am I toast ???

Here follows some additional data. Thank you
Bob Alexander
