I have a virtual machine with two disks,
sda2. I have a volume group (
vg_linux) with these two physical volumes and I want to remove
sda2 from this volume group. However, on this volume group, there is the root
/ logical volume, which is obviously mounted so I can't use
vgreduce vg_linux /dev/sda2.
I can't add more disks or change the storage system in any way.
Does somebody have an idea of a way to remove
