hi - why can't i use fdisk to partition a dm-crypt disk? tried to `sudo fdisk /dev/mapper/ea`, which is created by:
> `sudo cryptsetup open --type plain /dev/sda ea` fdisk shows my partitions: > Device Start End Sectors Size Type > /dev/mapper/ea-part1 2048 10487807 10485760 5G Linux filesystem > /dev/mapper/ea-part2 10487808 1953525134 1943037327 926.5G Linux filesystem but, as i save that partition table, i get this error: > Command (m for help): w > The partition table has been altered. > Failed to add partition 1 to system: Invalid argument > Failed to add partition 2 to system: Invalid argument if i repeat the execution of fdisk, i see that partition table, and if i hit `w`, it saves without showing that error. then, as i go to run `mkfs.ext4` on them, i can't see them under `/dev/mapper/`. rgrds, cm.
