Unable to Boot into ArchLinux Today (lemmy.ca)

Today, after decrypting my encrypted drive, the system failed to boot into it.

I forget what the error said. It maybe said that it could not fine new_root or something.

I tried something like the following, by I don't know what it does.

cryptsetup reencrypt --decrypt --header new_file device_path

I'm not sure what it does and what the --header part does. It was taking too long, so interrupted with a reboot. Now its saying their device is not a valid LUKS device.

I think you might have fucked your data.

  1. when you get an error like on your boot, take a screenshot, write it down, search online, ask for help with the exact error online

  2. when you don't know what a command does, don't run it

Afaik the command tried to re-encrypt your drive. If you canceled it, well now you have a drive in some undetermined state and since it was reencrypting it your data is now mumho jumbo.

The --decrypt option is used to remove LUKS encryption entirely and turn the partition into a normal storage volume.

Interrupting that process is still likely to have irreparably damaged the volume, making it impossible to recover.

Still, you've got backups, haven't you?
