Hello, I have a Centos 6.2 clsuter with a CLVM partition on which I have a GFS2 file system. The problem rises when I make a snapshot from my FC NetAPP FAS2020. After I make the snapshot (it is a rw snapshot) of my LUN, I am not able to mount it from any of my cluster nodes, because the Physical Volume is seen two times one time on the standard LVM partition and the other time on the snapshot partition so te PV is foudn to be duplicate and I cannot mount it.

I need a hint on how to fix this problem. I need to access the snaphot volume to backup my data but I am unable to do it...
thank you very much
