[sysstat]

Which version of sysstat are you using?

[Honghe]

Name : sysstat
Arch : x86_64
Version : 10.1.5
Release : 11.el7

[sysstat]

Please try latest sysstat version (11.5.5, available from my web site http:https://sebastien.godard.pagesperso-orange.fr/download.html).
Also try sar -dp instead of iostat -d: If the problem also happens with sar, create a binary datafile (e.g., sar -dp 2 5 -o datafile) and send it to me so that I can have a look at its contents.
