Hi, I have a couple of LUN's that are handled by the multipath driver. This works great, but now I want to use LVM so I can take snapshots of one LUN to another LUN. Can someone tell me how to do this? When I do pvcreate /dev/mapper/diskname I get an error that the disk is already part of an volume group. But I sertainly did not configure that. Can it be that the multipath driver of devmapper did that? Sander -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
