I am trying to locally deploy cockroachdb for use with Kubernetes on Rancher. I have created 3 Kubernetes persistent volumes with hostPath set as a local directory.
When I try to deploy cockroachdb through:
kubectl create -f https://raw.githubusercontent.com/cockroachdb/cockroach/master/cloud/kubernetes/cockroachdb-statefulset.yamltwo of the three created pods show error.
The logs of one of the failed pods show this:
I180202 08:47:45.224556 39 storage/engine/rocksdb.go:411 opening rocksdb instance at "/cockroach/cockroach-data"

Error: cockroach server exited with error: failed to create engines: could not open rocksdb instance: IO error: lock /cockroach/cockroach-data/LOCK: Resource temporarily unavailable
Failed running "start"`.The directory which is the hostPath of the 3 persistent volumes show this:
