So. I've tried these two now and thats what i get back :

You have no encrypt hook in your initramfs. You won't be able to do much with an encrypted root if you don't have this hook. You also need to fix the cable attaching the disk to the motherboard. Either it isn't seated properly, or there's a short in the wiring (this is what causes the DRDY errors and failed reads you see).

And please use code tags instead of quote'ing the output.....

netpumber · 2013-07-14 18:20:26

I add the encrypt into HOOKS line but i m getting the same error except the DRDY cause i move the cables

HOOKS="base udev autodetect modconf block lvm2 encrypt filesystems keyboard fsck"

falconindy · 2013-07-14 18:32:07

...did you regenerate the image before you rebooted again? You should see the 'encrypt' hook in the output of 'lsinitcpio -a' and you'll see the hook running at bootup after the second udev hook

@falconindy,
Doesn't the OP need the encrypt hook before lvm2 since the volume group is only available once the encrypted container has been decrypted?

That is, shouldn't it be

HOOKS="base udev autodetect modconf block encrypt lvm2 filesystems keyboard fsck"

?

No, not these days. The lvm2 hook is no longer stateful and ordering doesn't matter.

cfr · 2013-07-14 18:55:30

Cool . Thanks. I just remembered when I set this up a while back that the wiki explained the order mattered i.e. different order for LVM-on-LUKS than for LUKS-on-LVM. But there's been at least one major upgrade to lvm2 since then and I am obviously out of date .

You are right (i forgot to recreate the image).. Now the system seems to work. Thanks to all of you.

Glad you figured it all out . Please mark the thread [solved] by editing your initial post and tagging the subject line. Thanks!
