Clone to LUKS encrypted partition

[Afiro Nari]

Hi!

I have two partitions

$ lsblk
NAME       MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS
sda           8:0    0 931.5G  0 disk
└─sda1        8:1    0 931.5G  0 part
nvme0n1     259:0    0 931.5G  0 disk
└─cpart     254:1    0 931.5G  0 crypt

I want to copy unencrypted sda1ext4 partition into the LUKS encrypted cpart partition.

I tried to run part_to_local_part mode but there was no cpart option but only nvme0n1 in the target list. I chose nvme0n1 option and I wasn't asked for LUKS part open or something like that so I was scared to press ENTER because I think it can overwrite the whole nvme0n1 device.

After this I tried to enter shell mode and run # cryptsetup open /dev/nvme0n1 cpart and run part_to_local_part again, but the target options were the same.

I am confused why nvme0n1 is shown in part_to_local_part mode because it is the device and not a partition.

Please, help me understand how to do it right

In that case, I suggest you after running:
cryptsetup open /dev/nvme0n1 cpart
You can use partclone to clone that.
