KV节点扩容,ext4错误

在扩容的时候按照提示进行扩容,但是扩容失败,报错如下:

Ansible FAILED! => playbook: deploy.yml; TASK: tikv : Preflight check - Does tikv data dir meet ext4 file system requirement; message: {"changed": false, "msg": "You don't mount the file system of /tidata with ext4 nodelalloc option. See https://github.com/pingcap/docs/blob/master/op-guide/ansible-deployment.md#mount-the-data-disk-ext4-filesystem-with-options."}

扩容节点通过指令查询应该符合扩容条件:

我理解得加 nodelalloc 这个 mount option
