[SOLVED] Having Multiple LUKS container on a disk

I am interested in installing arch using the LVM on LUKS encryption method, I have read the wiki, but I have a question, I want to have a LUKS container for my install (swap,root,home), and one for my other LVMs like ones I store my files on, this way I can keep them seperated.

Does this reveal metadata because it should not since the LVMs are inside the LUKS containers?

I am asking this because I am still slightly confused about what reveals metadata and what does not, even though from what I understood having the LUKS containers inside the LVMs is how you reveal metadata and in my case it should not.

Not sure if I follow your question, but yeah you can use multiple LUKS containers, and multiple LVM PV/VG/LV inside them. You can set these up any way you want.

As for metadata, anything inside LUKS will be encrypted, and anything outside it won't.

So the metadata will be your partition table, some kind of bootloader mechanism, the boot partition (if unencrypted), and your LUKS headers.
