I would like to configure LVMs for everything including boot. I have read that others have done this but an I have not found the method.
While my desire is to boot from the LVM, I would consider an alternative, if I could find one. System description: amd64 with a HDD and 3 pairs of SSDs. The SSD are set up as RAID0 in pairs. The HDD currently hosts Debian 8. I used this to configure the SSDs to overlay the RAID0s with an LVM. The RAIDs were built on a second partition of each SSD. The first partition is 1G for potential boot use. I use a USB stick to load the second Debian. I have a lVM partition for the new installation. When I select it, the installer (in manual mode) says it is not bootable and go back to setup to correct. When I go back to setup, I don't see any way to do anything but select a VG, dm, sdx, or HDD. Worse case, I would consider reconfiguring the smallest pair of SSDs to include a RAID0 for just /boot. (I have tried to maximize for speed, but I have taken a hit for the RAID0 implementation. I tried the motherboard controller based RAID and benchmarked it with the Linux RAID. The Linux RAID was 10% slower but I selected it for reliability despite the speed loss - 10%). I would like to learn how to boot from the LVM and optionally, how to use the installer to configure the devices. Thanks in advance.
