Unable to teardown the rook

[khaninejad]

Hello,

I've followed this instruction to teardown my rook cluster but it stuck when I try to run the below command:

root@tb:/home/xxx/rook/cluster/examples/kubernetes/ceph# kubectl delete -n rook-ceph cephblockpool replicapool
cephblockpool.ceph.rook.io "replicapool" deleted

I waited like 24 hours to complete it but, no luck. Thank you

@khaninejad Was there any data in the cluster remaining? Rook will not delete the CRs if there are rbd images in the pool. The operator log should show errors about why the pool couldn't be deleted. You can also force remove the finalizers as described here

@travisn It was a fresh cluster, I followed the link and this is the result:

Where do you see those errors? In the rook operator log? This sounds similar to https://github.com/rook/rook/issues/9294. You are using K8s 1.22?

Please also open issues on the https://github.com/rook/rook repo, rather than this repo. I'll close this one here.
