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 base.. 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 free]   PV /dev/nvme0n1p1   VG vg0             lvm2 [<119,24 GiB / <91,80 GiB free]   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.
