[ceph-users] BlueStore and BlueFS warnings after upgrade to 19.2.1

Dear Ceph users, after upgrading from 19.2.0 to 19.2.1 (via cephadm) my cluster started showing some warnings never seen before: 29 OSD(s) experiencing slow operations in BlueStore 13 OSD(s) experiencing stalled read in db device of BlueFS I searched for these messages but didn't find much. I also noticed that when browsing the CephFS folders (using the kernel module for the client) sometimes the client gets stuck for a long time before showing the folder content; however I don't know if this can be related to the above warnings. I'd need help to understand what's going on and eventually how to troubleshoot it. Thanks, Nicola
