hi - why can't i use fdisk to partition a dm-crypt |
2 |
disk? |
3 |
|
4 |
tried to `sudo fdisk /dev/mapper/ea`, which is created by: |
5 |
|
6 |
> `sudo cryptsetup open --type plain /dev/sda ea` |
7 |
|
8 |
fdisk shows my partitions: |
9 |
|
10 |
> Device Start End Sectors Size Type |
11 |
> /dev/mapper/ea-part1 2048 10487807 10485760 5G Linux filesystem |
12 |
> /dev/mapper/ea-part2 10487808 1953525134 1943037327 926.5G Linux filesystem |
13 |
|
14 |
but, as i save that partition table, i get this |
15 |
error: |
16 |
|
17 |
> Command (m for help): w |
18 |
> The partition table has been altered. |
19 |
> Failed to add partition 1 to system: Invalid argument |
20 |
> Failed to add partition 2 to system: Invalid argument |
21 |
|
22 |
if i repeat the execution of fdisk, i see that |
23 |
partition table, and if i hit `w`, it saves |
24 |
without showing that error. |
25 |
|
26 |
then, as i go to run `mkfs.ext4` on them, i can't |
27 |
see them under `/dev/mapper/`. |
