@Alex: the issue is done for now, but I fear it might come back sometime. The cluster was running fine for months. I check if we can restart the switches easily. Host reboots should also be no problem. There is no "implicated OSD" message in the logs. All OSDs were recreated 3 months ago. (sync out, destroy, wipe, create, sync in). Maybe I will reinstall with ubuntu 20.04 (currently centos7) for newer kernel. Am So., 4.
