due to a failing hard disk, I would like to deactivate the volume groups living on it, to make sure that the disk is messed with as little as possible until it gets replaced.

I know that I can deactivate the logical volumes and the volume group with lvchange/vgchange --activate n, however as soon as the system is rebooted, these LVs and VGs get auto-reactivate.

I cannot understand how the auto-reactivation can be suppressed in ubuntu 20.04. The parameters that should be relevant in the lvm configuration appear to do nothing.

I suspect that in ubuntu the VG/LV auto activation logic sits in udev rules and completely ignore the lvm configuration. Is this the case? How can the desired behavior be obtained, then?

Any hint?

You can configure exactly which volume groups and logical volumes to auto-activate during boot using the activation/auto_activation_volume_list option in /etc/lvm/lvm.conf

This way you can list which vg's to activate, excluding the one you don't want to have auto-activated.
