Powerpath and lvm.conf filter
We use powerpath on RHEL servers, with at least 2 paths to each disk,
as you know the powerpath creates a pseudo devices called emcpowerX.
I was wondering if there is any overhead if we don't use the lvm.conf to filter out all sdX disks ?
Except the "duplicate PV found" messages on LVM, does it delays the boot of the server ?
