Please help me, I have a CEPH cluster with six nodes. Yesterday, one of the nodes reported insufficient disk space (image01.png), but using the command "ceph -s", it kept showing normal (image02.png). Before this, there was also a situation where the disk space of a certain node was insufficient. At that time, using the "ceph -s" command could normally display the alarm and the involved nodes. Why is this situation occurring now?
