Thread: LVM drive not showing up in clean 11.4 install

    Question LVM drive not showing up in clean 11.4 install

    Hi everyone. First off, I'm new to LVM so excuse me if I don't use the correct terminology, but what I have are two USB external hard drives joined into one drive using LVM.

    I originally set this up using 11.2 and then used it for months on a system with 11.1. The LVM drive would show up in the file system as /dev/mapper/Media-Media.

    I then upgraded that system from 11.1 to 11.4 using a clean install and a "minimal server" selection. Now, the LVM doesn't show up anywhere. In the YaST disk partitioner, it shows a "/dev/Media" as being of the type LVM2 Media with no logical volumes.

    What can I do to fix this?

    Hmm don't think I ever saw USB set up with LVM. Maybe the order that the devices are discovered may have some effect. How are you mounting them. Let's see the /etc/fstab.

    Back when it was working, I had the same concern regarding the order and I tried powering them on in the two different orders to see what would happen - it worked both ways.

    They aren't in /etc/fstab, but the drives are showing up as /dev/sdb1 and /dev/sdc1. Here is the output of "vgdisplay -v":

    Default SOLVED

    I found the solution. In "yast runlevel", in expert mode, there is a service, "boot.lvm" that must be enabled at boot time.
