[SOLVED] LUKS + LVM Fails To Mount After Switching To AHCI

jmanes · 2015-01-20 02:38:33

Hello everyone,

I set up my current arch install with LUKS on top of LVM by following the wiki article.

Everything works fine when the BIOS has the SATA controller set to Compatibility. However when I switch it to AHCI the system fails to boot. It seems /dev/mapper/lvroot is no longer found under these conditions. This is not a critical situation, but I am curious as to why this is.

Does anyone have any input? Here is my current partition layout if that helps anything.

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048            4096   1.0 MiB     EF02  BIOS boot partition
   2            6144          262144   125.0 MiB   8300  Linux filesystem
   3          264192       468862094   223.4 GiB   8300  Linux filesystem

Partition #2 is ext2.
Partition #3 is ext4 (LUKS)

Put ahci as a module in mkinitcpio.

This did in fact work! Thank you very much for the response.
