Hello mailing list, I currently sensed that LVM2 is not load balancing reads of mirrored LV's form their corresponding PV. PV1 PV2 LV LV' IO=0 IO=90MB/s [~]# lvm version LVM version: 2.02.39 (2008-06-27) Library version: 1.02.27 (2008-06-25) Driver version: 4.14.0 Distribution is Fedora 10, updated. Is this normal behaviour, or did a make a big mistake in my configuration?
