The PVE disks/list poll and the agent SMART report both observe a RAID
controller's exported volume, but PVE surfaces its NAA identifier as a
bare-hex serial while smartctl reports the same value as a naa.-prefixed
WWN with no serial. The linked-disk join compared serial to serial and
WWN to WWN verbatim, so the volume rendered twice (/dev/sda and sda)
with independent metric histories.
Hardware identity comparison now normalizes reporter framing (naa., eui.,
wwn-, 0x prefixes, case) and folds serial and WWN together before
comparing. Values are never truncated: sibling volumes on one controller
share their leading WWN bytes, and a truncated udev ID_WWN must stay
unequal to a full identifier. Placeholder serials no longer count as an
identity match.
