The setup is a Raid6 of 5 drives. As best I can understand, this is basically a warning caused by Raid itself duplicating the UUID on all of the drives, as it should. For some reason, though, LVM is now looking at each drive in the container instead of looking at the device the Raid is presenting to LVM.
Haven't changed anything in the conf file, but keep seeing a filter suggestion to resolve the warning. All LVM related commands show the same duplicate error. Don't know what changed that caused this to start happening, and it may have been going on for some time. I just noticed it when I needed to start investigating what might be a failing drive in the container. It only shows up when I issue an LVS type command or reboot. Being Centos, the reboot rarely happens.
Thanks for the reply. I know I'm not offer much help here, so sorry for that.

I've got a situation here where my LVM is showing the following problem:
Found duplicate PV xxxxxxxxxxxxxxxxxxxxxx: using /dev/sdb2 not /dev/sda2
Not sure what causes this and I really don't have a clue as to what the consequences are when seeing this or how to fix it. Google just confuses me with any suggestions.
Can anyone offer any help, please?

What is the setup supposed to be? Have you altered lvm.conf in any way? What does 'pvscan', 'vgscan' and 'lvscan' show? What, if anything, happened before this issue arose?
