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
