I don't see any duplicates there, either. Are there any other DASD volumes
on that system? The vgdisplay was definitely complaining about a PV with a
signature that duplicated another PV. That could happen a number of
different ways, including if you have PAV active.
Using "vgdisplay -v" and then, perhaps, "vgdisplay -vv" will show more of
what the system thinks is there. You could also look at the backups of the
LVM data in /etc/lvm2/archive/ to see what has happened over time. I just
did an "ls -latr" of that directory, and chose the most recent archive to do
a "grep 'id ='" command on it:
grep "id =" archive/data_00048-2101112826.vg
id = "CJRU0H-GAWq-6WZi-Y0dE-CPWf-xvXD-kIZDaq"
id = "Zr1UZh-3PBB-cr7K-yyNT-fjEh-2Qee-pxD5gK"
id = "gJyBme-yTWu-k3pp-rBQ6-tXzf-m0bT-2GJ778"
id = "SFxps5-640p-FmoW-cTqV-80xo-pedq-EsWGTi"
id = "Z6O3sk-Lt4V-dZOA-CxqO-YNIS-kF8T-cWGZ3U"
id = "6GzQvg-OVuZ-2UHH-xWzh-k8Uj-ma7x-0DEtp3"
id = "wmFKzb-RrEN-yMoY-biH0-YFnl-un2j-dWb9Ws"
id = "eFpOCh-jc6l-1kRt-eyNq-cfBT-Jtfs-bmlBJJ"
id = "o0tGck-oYRP-yeVe-CP9c-iEVh-a9Jt-nRcAeg"
id = "H1axI5-rrPz-MZaD-npNt-pqK8-D53b-kQameC"
id = "AprE7W-VoWN-W2jA-RY3j-2g35-9w3x-1pKQqT"
id = "reMJ43-wFau-VJG3-LOQv-QeQL-FWNn-1nngV2"
The first entry is for the VG. The other entries are the signatures of the
PVs that make up the VG.
