There are better tools for investigating this type of I/O issue.

You could have a read of this article that explains how to track down disk I/O

Thanks Barry, I'll have a look at that. I have added disk I/O to the HTOP summary display at the top of its screen which has highlighted, in my view, that HTOP is doing things wrong, as the summary display says the disk I/O is 100% but the details display on what is performing I/O says that nothing is doing any I/O.

If you are interested in systems performance have a look at getting
Brendan Gregg's "Systems Performance" book.

I'll have a look at getting that too, as I had an issue this morning when I put on the available updates with DNF, in that when DNF was applying the updates it locked my system out, I couldn't even move the mouse pointer until DNF was finished.

regards,
Steve
