Prevent automatic volume group activatation at boot time

How to prevent automatic volume group activatation at boot time?

Platform :

Red Hat Enterprise Linux

lvm

Resolution

In /etc/lvm/lvm.conf file add

volume_list = [ "vg1" ]  

Which means only vg1 out of may vg's is activated at the time of booting. Other vg's will remain deactivated.

Root Cause

-- snip from /etc/lvm/lvm.conf --

# If volume_list is defined, each LV is only activated if there is a
# match against the list.
# "vgname" and "vgname/lvname" are matched exactly.
# "@tag" matches any tag set in the LV or VG.
# "@*" matches if any tag defined on the host is also set in the LV or VG
#
# volume_list = [ "vg1", "vg2/lvol1", "@tag1", "@*" ]
