Hi Neil, |
35 |
|
36 |
only to be sure to have understood everything correctly: |
37 |
Suggestion is to create for example one root partition and a swap |
38 |
partion. And I will create on big "rest of the disk"-partition. |
39 |
The last one will be subdivided with LVM into portions as needed. |
40 |
|
41 |
Since the last big partition is big due to physical reasons (not for logical one): |
42 |
What will happen, if -- for example -- one portion will be not unmounted cleanly |
43 |
and while booting/checking fails to recover? Are all others |
44 |
damaged/lost? |
45 |
|
46 |
Best regards, |
47 |
