但是在尝试创建应用时，却一直卡在DEPLOYING状态，点击后点开Application Events，提示waiting for a volume to be created, either by external provisioner "zfs.csi.openebs.io" or manually created by system administrator。由于没接触过k8s，只能网上搜索该错误提示。
有人说是因为权限问题，选择给ix-applications目录赋予777权限，完全没有解决。
定位问题
仔细查看出错提示，猜测问题可能出在zfs.csi.openebs.io。查询openebs的官方文档：OpenEBS Documentation | OpenEBS Docs，进入ZFS Local PV分页，在README中发现使用kubectl get pods -n kube-system -l role=openebs-zfs可以查看ZFS驱动的运行状态（注意在TrueNAS中需要使用k3s运行该命令，即k3s kubectl get ...）。输出：
NAME READY STATUS RESTARTS AGE openebs-zfs-node-wqn2v 1/2 ImagePullBackOff 0 7h43m openebs-zfs-controller-0 1/5 ImagePullBackOff 0 7h43m
很明显驱动没有正常运行，查询ImagePullBackOff错误提示，得知是镜像拉取失败。运行k3s kubectl describe pod openebs-zfs-controller-0 -n kube-system查看pod的状态，主要看Events部分的输出：
