Hello, We have a cluster in version 17.2.5 and on 2 nodes (out of 5), some metrics are at 0 on all OSD. The problem is really global to the node. I performed an upgrade to 17.2.6 on the cluster like this : * upgrade all monitors * upgrade all mgr * then reboot each node one by one (there was a pending upgrade of linux kernel image) to upgrade all OSDs This fixed for one node of the cluster but not the other so I stil don't understand. Here is an example of such OSD : { "AsyncMessenger::Worker-0": { "msgr_recv_messages": 6843132, "msgr_send_messages": 6880681, "msgr_recv_bytes": 63926805259, "msgr_send_bytes": 3298578019,
