I could not startup my old Qnap, but there was a lot of data on disk(1).
My aim was to mount this in my zimaos machine. I needed lvm and this was not available
Right now I installed a temp ubuntu container and could mount it. Below there where a couple of commands.
docker run -it --privileged --net=host -v /dev:/dev -v /mnt:/mnt ubuntu /bin/bash
mdadm --assemble --run --force /dev/md127 /dev/sdc3
vgchange -ay
I managed to mount it, but it is in the container.
It looks a bit clumsy and the disk is not visable in gui (stuck in container). Is there a better way to do this?
