As if yesterday I added 10 OSD's total 2 per node, the rebalance started and took some IO but seemed to be doing its work. This morning the cluster was still processing the rebalance and taking so much IO that nearly all OSD's where marked as "slow ops" and from there everything went wrong. As attempt to clear as much IO for de rebalance I stoped all the clients and waited for the rebalance to finish. After it finished the cluster remained extremely slow and unusable. Whilst trying to debug I restarted several services and nodes trying to find the problem. Now the cluster has entered a state where multiple OSD's remain slow, various OSD's show a "BADAUTHORIZER" message and the mgr on all nodes also has issues "verify_authorizer". > > I verified all the clocks on all servers and they are sinked to the same NTP service and seem good. > > Please please please advise as straight 13 hours of debugging got me nowhere. If you can pause all client IO, I don't think it can harm to upgrade everything to 14.2.11, just to be sure you don't hit a bug that is already fixed. But it depends on the current health of your cluster I guess. Gr.
