I was wondering if anyone had any suggestions how to monitor upgrade progress? We have some instances with a large number of tables and it would be good if we had some idea where we are in the upgrade.
fwiw I’ve tried monitoring files with lsof but I couldn’t see it reading the .frm files etc…
Your best bet is to simply
tail -f MySQL’s error log. There will not be much output, so set your expectations low here.
Thanks @matthewb that’s what we had concluded. I was hoping someone had come up with a cunning method. Thanks again.
