tiup cluster check report fail unexpectly

Bug Report

Please answer these questions before submitting your issue. Thanks!

1. What did you do?

I run this command

tiup cluster check testing --cluster

2. What did you expect to see?
   No Fail.
   I do not deploy tikv on the 172.16.4.84 node. So I think it's ok that mount point / does not have 'nodelalloc' option set. Here is a part of my topology.yaml that is related to 172.16.4.84.

global:
  user: "tidb"
  ssh_port: 22
  deploy_dir: "/home/testing/deploy"  # for monitor components
pd_servers:
  - host: 172.16.4.84
    ssh_port: 22
    client_port: 2379
    peer_port: 2380
    deploy_dir: "/data1/testing/pd-2379"
tidb_servers:
  - host: 172.16.4.84
    ssh_port: 22
    port: 4000
    status_port: 10080
    deploy_dir: "/data1/testing/tidb-4000"
    numa_node: "0"
monitoring_servers:
  - host: 172.16.4.84
    port: 9090
grafana_servers:
  - host: 172.16.4.84
    port: 3000
alertmanager_servers:
  - host: 172.16.4.84
    web_port: 9093

3. What did you see instead?

172.16.4.84  disk            Fail    mount point / does not have 'nodelalloc' option set
172.16.4.84  disk            Warn    mount point / does not have 'noatime' option set
172.16.4.84  disk            Fail    mount point / does not have 'nodelalloc' option set

4. What version of TiUP are you using (tiup --version)?

[root@localhost data-testing]# tiup --version
v1.3.2 tiup
Go Version: go1.13
Git Branch: release-1.3
GitHash: 2d88460
[root@localhost data-testing]# tiup cluster --version
Starting component `cluster`: /root/.tiup/components/cluster/v1.3.2/tiup-cluster --version
tiup version v1.3.2 tiup
Go Version: go1.13
Git Branch: release-1.3
GitHash: 2d88460

Start by reproducing tiup cluster check testing --cluster with the topology and TiUP v1.3.2 details provided in the report. Trace the cluster check disk validation and compare its handling of the node roles and mount-point warnings; done when the command reports the expected result for this topology without the inappropriate failure.
