Non riesco a fare il boot
Ciao a tutti, su un PC con 2 dischi in raid 1 (md1) software utilizzati
come pv di un lv su cui ho installato debian ho aggiunto altri 2 dischi:
ho quindi creato un nuovo raid 1 sui 2 dischi (md0) e li ho aggiunti
come PV quindi ho fatto il grow del volume logico su cui avevo
installato debian, Al boot ora non parte più, da un errore e compare il
prompt della console di grub:
error: disk
'lvmid/ROCH5Y-fqDh-ApY2-jC0e-vfr9-7Asx-ECw328/H8Osen-SR2M-52Ly-j1eR-mXDP-cFYX-YugNgi'

Da una live ho eseguito:
# mount /dev/mapper/vg--root-lv--root /mnt
# mount -t proc none /mnt/proc && mount -o bind /dev /mnt/dev && mount
-t sysfs sys /mnt/sys
# chroot /mnt/ /bin/bash
ho provato a lanciare grub-install /dev/sda ma da i seguenti warning:
# grub-install /dev/sda

Grazie!
