You are correct, this wasn't the case in older kernels because /sys/block did not include certain types of block devices. Unfortunately this is no longer the case :-/

Hi Dag
(Dstat 0.7.0 on RH6)
The same issue is with virtual Veritas (VxVM) devices:
Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util
sdh 0,00 1,00 1,00 1800,00 0,01 108,95 123,90 2,04 1,14 0,11 19,40

dstat doubles the disk throughput:

Can someone verify if this problem still affects master ? Since I cannot reproduce it, someone may already have fixed it.
I'd like to release 0.7.3 sooner rather than later...

@franklimstrand I cannot reproduce it on a RHEL6.5 system:

As you can tell, the total value does not include the logical volumes (dm) devices.

Dstat is including the VxVM (meta) device which it should not? The VxVM device is the sum of sdan and sdct.
HTH.

@franklimstrand Oh I am sorry. I thought this was still related to LVM devices (from the topic) and misread your comments. VxVM devices are new to me, but I included it now to the diskfilter so these devices are excluded from the total value. (See commit 5f5481b)
Please test and reopen if it doesn't do what is expected. Thanks !
