You shouldn't be getting duplicate PV messages in the first place. Trying to change the LVM filter isn't going to help. You need to figure out why you have two disks with the same UUID, but they're of different sizes. 0.0.0400 active dasdf 94:20 FBA 512 80MB 163840 0.0.0607 active dasdp 94:60 FBA 512 2048MB 4194304 Something is very wrong there. The only ways I can think of to get duplicate PVs is by not having multipathing set up right, or cloning minidisks and having them both active on the guest. I guess another possibility is that you've got a minidisk defined incorrectly in z/VM. You might have some overlapping extents. What does running diskmap against the user directory show you? Why do you have so many DASD volumes in the first place? They look like z/VM EDEVs from a storage array. Why not just make them big enough to hold what you need?
