Is this happening on a node install or have this node previously worked?

If the former...

1. Verify SELinux is disabled

2. Run "df" from the CLI to ensure it responds in a timely manner

3. Verify you can ssh to the machine with the credentials you used for install

4. Verify you can reach the agent port (7182) from the CM.

5. Restart the agent

If the later...
1. Have there been any filesystem changes? Check "df" to make sure it responds properly.

2. Verify forward and reverse DNS is working.  You can use the CM Network Inspector for this.

3. Restart the agent

[#3]

This is for new cluster. Installations all are done Present it was in production.  This was happen Name node. some times in day (10 to 20) min it was not SYNC with NFS server. we are getting all running services facing clock offset Alerts.

[#4]

If I understand your response, you have an NFS Server that’s timing out and clock offsets are out of sync. 

For the former, the NFS admin needs to address this. It’s not typical to run NFS on a Namenode BTW. 

For time sync, you need to be running NTP or chrony
