Found LVM2 physical volume signature
2147479552 kB data area apparently used
2147418076 kB left usable by current configuration

Device size would be truncated, which
would corrupt data and result in
‘access beyond end of device’ errors.
You need to either
* use external meta data (recommended)
* shrink that filesystem first
* zero out the device (destroy the filesystem)
Operation refused.
