I am using a raid5 array as a pv and it has a 1.5 MB stripe width, so logical volumes should be aligned to that, but it appears lvm is not doing this. It looks like you can specify this alignment at pvcreate time, but I don't think I did and it doesn't seem to have been picked up automatically. Is there a way to change this without rebuilding the vg? -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJRGliwAAoJEJrBOlT6nu75u38IANP/fcPpeXdzymKzDBmKFjJ/ hVSR0Ig8lcym3nbL9wCz/PIGRrta5j9M2lVrIoMP68iTcywqsyON7f+iPN3f20MO v3Vjm0kRET4rw8inJE2g+6o5RlOAn+45vN6G6LtkncPFEo8MhxwHO2EMno3nql7Y Ds5eFd9OjK8BkpUaMjzUJR61of5SL32HXTAm7mVMXSzV1IIzFvSMq8P5bzI6GGnx mtoMqcND64+5AvU/FBnmB12k0MVNbnpLRvj1CZnhM8rrHu5cN921O1zK3M8rZ7sb vk9GalquS+AuELBwLOiY2t6a5ebW2aWB4Yi2docdOjudeN1y7LrvgmNmhIbxE+k= =C45A -----END PGP SIGNATURE-----
