I'd like this, too. cfdisk displays them, but is not abel to edit. |

It's not that complicated. In a nutshell: |
| 14 |
|
| 15 |
Choose the partitions you want to use for LVM, and prepare them to be |
| 16 |
physical volumes: |
| 17 |
pvcreate /dev/sda[678] |
| 18 |
|
| 19 |
Create a volume group out of these partitions: |
| 20 |
vgcreate myvg /dev/sda[678] |
| 21 |
|
| 22 |
Create logical volumes in this volume group: |
| 23 |
lvcreate -L 5G -n lvm1 myvg |
| 24 |
lvcreate -L 2G -n lvm2 myvg |
| 25 |
|
| 26 |
Use these logical volumes just as disk partitions: |
| 27 |
|
| 28 |
mke2fs -j -L fs_on_lvm /dev/myvg/lvm1 |
| 29 |
mount /dev/myg/lvm1 /mnt/fs_on_lvm |
| 30 |
|
| 31 |
The file system is too small? Just extend its size by 1G, without |
| 32 |
unmouning: |
| 33 |
|
| 34 |
lvresize -L +1G /dev/myvg/lvm1 |
| 35 |
|
| 36 |
The volume groups is getting full, no space to add LVMs? Add other |
| 37 |
partitions. If you like, even from a 2nd drive: |
| 38 |
|
| 39 |
pvcreate /dev/sdb5 |
| 40 |
vgextend myvg /dev/sdb5 |
| 41 |
|
| 42 |
So, it's of course more complicated than just firing up cfdisk, create |
| 43 |
partitions and file systems on them, but you have much more flexibility. |
| 44 |
Once you have LVM, you do not have to care what the actual device names of |
| 45 |
your drives are. If sda becomes sdb and vice versa, no problem, and |
| 46 |
nothing to worry about. LVM does not use the device name, it scans each |
| 47 |
partition and uses the LVM UUIDs on them to identify what is what. |
