我正在尝试本地部署 cockroachdb ,以便与Rancher上的Kubernetes一起使用。我创建了3个Kubernetes持久卷,并将hostPath设置为本地目录。
当我尝试通过以下方式部署cockroachdb时:
kubectl create -f https://raw.githubusercontent.com/cockroachdb/cockroach/master/cloud/kubernetes/cockroachdb-statefulset.yaml
三个创建的pod中的两个显示错误。
其中一个失败的pod的日志显示:
I180202 08:47:45.224556 39 storage/engine/rocksdb.go:411 opening rocksdb instance at "/cockroach/cockroach-data"
E180202 08:47:45.285297 1 cli/error.go:68 cockroach server exited with error: failed to create engines: could not open rocksdb instance: IO error: lock /cockroach/cockroach-data/LOCK: Resource temporarily unavailable
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"`.
作为3个持久卷的hostPath的目录显示:

我尝试为牧场主设置nfs,但目录显示rancher-nfs不兼容。
