Hi, I was reading a lot of data from one LVM logical volume and wanted to watch the disk statistics with iostat today. To my surprise, I was seeing the same activity on two logical volumes (LV) and the physical disk containing the two. A little investigation showed that one LV was a snapshot of the other, and I was reading from one of the snapshots. While I understand that the two LVs share some common Logical Extents (LE), I believe it is a bug that the disk statistics show the activity on both logical volumes. Should I report this in the centos bugzilla or upstream's bts? Thanks, Mike Fedyk
