Details

Recently, running iotop displays a warn and does not behave as it did in the past. The warning is, "CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and IO %" and I am see a loss of output in the display relating to these two items. Interestingly, this option is in fact enabled in the kernel. Packaging bug? Upstream bug?

% zgrep -i task_delay /proc/config.gz
CONFIG_TASK_DELAY_ACCT=y

Additional info:
* package version(s) iotop 0.6-8
This task depends upon

Have you tried applying the commits below? ( Note ab35334d374e588bec12d201fb8869c536f0545d does not apply cleanly without manual adjustment )

https://repo.or.cz/iotop.git/commit/dd4fcc71b1184264bed25fbc0ce7e2d758d8c396

I applied both after adjusting them (see attached single) but it did not fix the bug.
   tryfix.patch (4.8 KiB)

Did you also set the sysctl kernel.task_delayacct to 1?
Comment by John (graysky) - Thursday, 07 October 2021, 08:30 GMT
I did now. Using the patch and setting the variable to 1 gives the expected behavior.

Is it possible to add the [kernel] tag to this FS? Seems like toggling the setting for basic functionality is a work-around/should be set in the kernel config unless there are downsides.

is this issue still present, or gone by now?
quick start of iotop on my machine, I don't see any warnings

I still get the CONFIG_TASK_DELAY_ACCT not enabled message.

Although I just noticed graysky's comment. Setting kernel.task_delayacct=1 makes it work.
