Thanks for your information, I tried to new some mds pods, but it seems the same issue.
[root@vm-01 examples]# cat filesystem.yaml | grep activeCount
activeCount: 3

[root@vm-01 examples]# kubectl get pod -nrook-ceph | grep mds

kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.
