That would also work - having separate VGs helps ensure each swap device |
| 11 |
ends up on its own physical device. It could certainly be done using |
| 12 |
explicit device assignments when creating LVs. |

In any case, moving around swap devices is a piece of cake compared to |
| 15 |
moving around data, so it isn't a big deal either way. I wanted to |
| 16 |
separate two data LVs on separate physical devices and I did it exactly |
| 17 |
how you suggest keeping them in the same VG for future flexibility - |
| 18 |
moving LVs containing data is a real pain if they are in different VGs. |
| 19 |
With swap I just swapoff one device at a time making sure the total |
| 20 |
swap is sufficient at all times and the system moves around the data |
| 21 |
automatically... |
