LVM ridimensiona il process

Da qui, come posso ridimensionare lo spazio nelle partizioni / usr, / var e / home senza dati danneggiati, se posibile e in modalità normale (nessuna modalità di ripristino) in quanto è un server remoto. Ho visto altri post ( Come ridimensionare l'arrays RAID1 con mdadm ? , Linux: crea software RAID 1 dalla partizione con i dati ) e docs ma non sono sicuro del process. Grazie.

    Se si desidera aggiungere un altro 10 GB al vostro /usr portndolo fino a un totale di 15 GB è necessario utilizzare comandi come questo (supponendo che i file system siano ext2,3 o 4) {ref} .
