I cannot help if I don't know what dstat version and what kernel. On my system I do not see that behaviour, but it is not impossible that this behaviour exists with older dstat versions and/or older or newer kernel versions. This bugreport is useless if it does not specify this minimum information, sorry. -- -- dag wieers, d...@wieers.com, http://dag.wieers.com/ -- [Any errors in spelling, tact or fact are transmission errors] -- Disk total stats are double https://bugs.launchpad.net/bugs/307961 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
