It can be used that way, but you have only one disk, so you would create a single physical volume from a large partition on that disk and then use LVM to create individual logical volumes within it. > What is the advantage of using LVM and several small partitions > instead of one in the size of the sum of the others and not using > LVM? Flexibility and convenience. No single filesystem is right for all of your needs, with LVM you can use XFS where it is best suited and something else elsewhere, and you can resize and reorganise your volumes without needing to repartition the drive. I have a few hundred GB unused on my volume group, so I can add volumes or resize existing ones in seconds with minimal effort and no downtime. Just one note of caution, XFS filesystems cannot be shrunk, although they are easy to grow, so make any XFS volumes no larger than your current needs. That advice applies to all your volumes, because growing is easier and faster than shrinking, but doubly so to XFS. --=20 Neil Bothwick Better to understand a little than to misunderstand a lot. --Sig_/NuFhPJkKr3JsAwbDOdBPA17 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEARECAAYFAku1ytAACgkQum4al0N1GQPU2wCfdN41j/QxnPzL6I1WF/fCAX5N Wz0AnjtBdsGCms8W05sJsHvtKgJ8iqlt =7dnA -----END PGP SIGNATURE----- --Sig_/NuFhPJkKr3JsAwbDOdBPA17--
