Public bug reported: Binary package hint: sysstat
Upstream bug I suppose, but sysstat adds together the block I/O of a partition and the disk it is on, double-counting all the I/O to or from a disk. WIth LVM, sar counts the I/O to the PV and the I/O to the LV. This makes the figures reported by sar -b effectively useless. Sar should take the topology into account, and not double-count.
