Subject: [alpine-user] alpinelinux 3.3.1 can not boot, when root is on lvm, which is on
 raid1

Hi,

I installed alpinelinux 3.3.1 with manual disc mode.
My root is a logical volume in a volume group on a raid1 system.
During boot the raid is activated, but the logical volumes are not.
So I have to activate it manually and mount it to /sysroot.
After that I can boot into alpinelinux.

Is it a known problem, that lvm on a raid is not activated in the
initramfs during boot ?

My /boot is on a usbstick and sdc is a backup disc.

Here some data from my setup:

Can anybody see where I did a mistake ?
