Cannot format device luks encryption

[hasty sable]

Basically while configuring an encrypted volume, it shows cannot format device. Anyone could help me on this I don't think there's an error with my command tho

[gusty solar]

are you trying to set up luks on the drive you are currently running?

[hasty sable]

No

It is a new nvme

[hasty sable]

I am installing gentoo on it with luks but I couldn't find the solution of the cannot format device error

[gusty solar]

try cryptsetup luksDump /dev/nvme0n1p3

[hasty sable]

oh wait

[gusty solar]

is the /dev/nvme0n1p3 partition set up as Linux filesystem?

[hasty sable]

yes

├─nvme0n1p1 259:1    0   512M  0 part 
├─nvme0n1p2 259:2    0    32G  0 part 
└─nvme0n1p3 259:3    0   206G  0 part```

[hasty sable]

p1 will be my efi
p2 swap
p3 filesystem

[gusty solar]
