sd-encrypt over ssh

I have a computer encrypted with LVM on LUKS : one HDD and one SSD in the same LVM virtual group. on the group there is /root and /home.

I wanted to be able to wake over network so I checked the wiki but this seems to only work for the encrypt hook, and I checked the encryptssh hook but I don't understand it.

My hooks are :

 HOOKS=(base systemd autodetect keyboard sd-vconsole modconf block sd-encrypt sd-lvm2 resume filesystems fsck) 

The commands for grub contain

 rd.luks.name=uuid1=cryptssd rd.luks.name=uuid2=crypthdd root=/dev/Vols/root 

Is there something to be done ?

and the Shadow shall lie across the Pattern of the Age,
and the Dark One shall once more lay his hand upon the world of man.

Re: sd-encrypt over ssh

I don't use ssh in my initramfs but the wiki page you mentioned certainly has a section for a systemd based initramfs. systemd-tools seems like the thing you are looking for.

Re: sd-encrypt over ssh

I have a similar setup: lvm on top of luks and use ssh in my initramfs to unlock it via network. I use the netconf and tinyssh hook, as described here:

Everything is explained in detail in the wiki, I never tried the systemd hooks....

Re: sd-encrypt over ssh

AFAIK has the encryptssh hook (like the encrypt hook) no way to specify multiple disks, meaning that encryptssh is unsuitable here.

Do you mean Wake on Lan?  How is being able to wake the system remotely connected to your encryption usage?

It seems you answered this in another thread some time later so I'm linking to it as this was the first thread I hit when looking this issue up.
