Storage Analysis: pvmove Source Device

Data is being migrated off a failing disk with a live pvmove. To confirm the operation targets the right disk, identify the source physical volume. A capture of the operator's session — pvs, the pvmove command they ran, and its progress — is at /root/storage/pvmove.txt; the devices differ per session.

pvmove SOURCE [DESTINATION] moves extents off the first device named (the progress lines report the source too). Record the source PV's device path to /root/answers/pvmove_src.txt.
