Did you multiply the number of extents reported by pvdisplay with the |
| 31 |
extent size? lvextend's -L uses megabytes, if no unit is given. To |
| 32 |
specify extents, you should use "-l". You should also prefix the number |
| 33 |
with a "+" so that the number is relative to the current size, not the |
| 34 |
absolute size of the logical volume. |
