The lvchange command is used to change the attributes of a logical volume. Issuing the lvchange command on a volume group that contains
a mirror or snapshot may result in messages similar to the following:
Unable to change mirror log LV fail_secondary_mlog directly
Unable to change mirror image LV fail_secondary_mimage_0 directly
Unable to change mirror image LV fail_secondary_mimage_1 directly
These messages can be safely ignored.
