Subject: [linux-lvm] Unknown PV missing ?
Date: Sun, 17 Feb 2019 15:57:22 +0100	[thread overview]
Message-ID: <> (raw)


I've this computer running since a very long time on the same LVM 
configuration consisting of 2 PV  and one VG onto which the whole system 
is installed (it is bare metal running now Ubuntu 18.04.2 LTS.).

Every time I do an upgrade-grub, I get the following message :


Création du fichier de configuration GRUB…
/usr/sbin/grub-probe : attention : Impossible de trouver le volume 
physique « pv0 ». Certains modules risquent de manquer dans l'image de 
Image Linux trouvée : /boot/vmlinuz-4.18.0-15-generic


IF I do a pvscan -v I get this :


# pvscan  -v
     Wiping internal VG cache
     Wiping cache of LVM-capable devices
   PV /dev/md1         VG vg0             lvm2 [<291,91 GiB / 126,66 GiB 
   PV /dev/nvme0n1p1   VG vg0             lvm2 [<119,24 GiB / <91,80 GiB 
   Total: 2 [411,14 GiB] / in use: 2 [411,14 GiB] / in no VG: 0 [0   ]

And this is the extract of vgdisplay -v pertaining to PVs

   --- Physical volumes ---
   PV Name               /dev/md1
   PV UUID               gcjLSH-3lL5-NjBq-QdYh-vddQ-pwlg-UmEiZs
   PV Status             allocatable
   Total PE / Free PE    74728 / 32426

   PV Name               /dev/nvme0n1p1
   PV UUID               UGWM1s-GSly-Riyp-3hfE-s2nr-ng2E-wNuTVS
   PV Status             allocatable
   Total PE / Free PE    30525 / 23500



Nowhere is a "pv0" referenced. So I wonder what is this pv0 and from 
where it comes ?

Could you, please, help me get rid of this message ?

Because it puzzle me since a long time and I can't find how to suppress it.

Many thanks in advance for your help and advice.
