OK, since nobody answered, let me perhaps ask a different question.
Is there any way to prevent any automatic LV activation/deactivation?
And have full manual control via lvm_lv_deactivate/lvm_lv_activate?
Setting activation = 0 in global section of lvm.conf did not do the
job, because then lvm_vg_create_lv_linear fails, so I even cannot
create a LV.
Thanks,
Alex.
