Recientemente instalé LVM en Ubuntu 18.04 ejecutándose en una estación de trabajo física y luego creé mi primer LV. Después del primer reinicio encontré un problema porque ya no puedo activarlo.
Noté este error:
root@lvrome:/var/log# pvdisplay -v

Estoy seguro de que no he cambiado el tamaño de los PV después de la instalación. Por cierto, los creé a través de pvcreate /dev/sdb /dev/sdd, vgcreate backup_vg /dev/sdb /dev/sdd, lvcreate --type striped -i 2 -l 100%FREE -n backup backup_vg.

Respuesta1
El orden en que se enumeran los discos no es persistente entre reinicios. Por lo tanto /dev/sdb, podría /dev/sddrevertirse cada vez que reinicie el sistema. O cambiado con /dev/sdao /dev/sdc. O algo mas.
Si está haciendo algo que depende de hacer referencia al mismo disco físico cada vez que arranca el sistema, es mejor usar los enlaces simbólicos ya /dev/disk/by-idque Linux se asegura de que siempre apunten a los mismos discos físicos, incluso si sus /dev/sd*especiales cambian.
Por ejemplo:
pvcreate /dev/disk/by-id/ata-SEAGATE-ST3160813AS_*whatever # you hid the serial number
Técnicamente estono deberíaser necesario con LVM ya que utiliza sus propios UUID internamente para todo, al menos después de crear los PV, pero es un buen hábito.
