1) Check which Volume Group have the issue , run “vgscan” command .

2) Find out the Logical Volumes attached with that Volume Group .

3) Inactive the logical volumes as :

# lvchange -an <lv-name>

4) Inactive Volume group as :

# vgchange -an <vg-name>

5) Again Scan Volume group using “vgscan” .

6) Now activate the Volume Group :

# vgchange -ay <volume-group-name>

7) Run command “lvscan” , the error should be gone now .

8) Now activate the Logical Volume Name :

# lvchange -ay <lv-name>
