If a PV was removed +from a VG while it was missing, and the PV reappears, using +this option will clear the outdated metadata from the previously +missing PV. If metadata text is damaged on one PV, using this +option will replace the damaged metadata text. For more severe +damage, e.g. with headers, see \fBpvck\fP(8). +. +.HP +\fB-v\fP|\fB--verbose\fP ... +.br +Set verbose level.
