[SOLVED] "error: no such cryptodisk found" followed by normal boot

bestfriend · 2023-03-04 19:52:14

Issue

My system has a LUKS1 encrypted btrfs filesystem which includes /boot in the encrypted volume. GRUB is installed to /efi, which lies on its own unencrypted partition. I've had this setup for well over a year working fine. About a month or two ago, after a GRUB update, I began to get error messages at boot. My system seems to run fine, but I also don't understand what is triggering the message.

Symptoms

On boot, I am prompted for my crypt password. After unlocking, I get to GRUB. After selecting Arch Linux, I get

error: no such cryptodisk found, perhaps a needed disk or cryptodisk module is not loaded
Loading Linux linux ...
Loading initial ram-disk ...

Press any key to continue...

Continuing or simply waiting causes the initram to post normally. These are the same symptoms as described in this post, which didn't seem to provide a conclusive answer.

Any more ideas to continue the discussion? Thanks!

Did you follow the packager's advice above?

bestfriend · 2023-03-05 02:56:12

Ah, silly me... reinstalling fixed it. Thanks.

I had remade the config a couple times to no avail, but actually using grub-install fixed it.

Strike0 · 2023-03-05 10:44:59

You're welcome. The grub-install is needed again when grub modules are updated that your system uses (like the cryptomount you researched in this case). Just re-generating the grub.cfg (which describes the defined grub menu entries) does not help here, because the modules are embedded into the binary generated by grub-install to be booted to access the menu. It's important to double-check after re-running grub-install, though, as any errors are very likely result in an unbootable system. That's also a reason the package does not perform the commands automatically.
