What could be the reason for the many pod reboots

[Dmitry Bobrovsky]

Hello!

rook-ceph 1.4. 

kubernetes 1.19.

This is development cluster deployed on one node.

I see many pod reboots. Sometimes the ceph becomes unavailable at all. But i don't understand what is the reason for this.

k -n rook-ceph get pod

NAME                                            READY   STATUS    RESTARTS   AGE

rook-ceph-tools-54c767bfbb-pdhpr                1/1     Running   39         293d

How can this be diagnosed? or

Where can I start to investigate this situation?

The liveness probes may be failing. Check with “kubectl describe <pod>” to see the liveness probe status. How much memory does the node have? It may need more.
