Cloudera management service any service not running

[#1]

hello i'm using CDH 6.2.0.

I have a problem with the Cloudera management service not running.

When I turn on the cloudera-scm-agent and cloudera-scm-server, it looks like the picture below.

And when I run a service, I get a message saying "Role not started due to unhealthy host".

this is my cloudera-scm-agent log.

i don't know how to solve this problem.

(add message)

This problem occurs when the cloudera files in /var/lib are moved to another disk and linked. And Permisson is already changed.

Hi,

aren't there networks problems?

[#3]

no. I've been using it well before, and I have this problem since I added something new to my topic.

Hello @meenzoon It seems the Cloudera Manager Service itself is not running. Could you please check the CM Server (#service cloudera-scm-server status)  status on the host? If not running, please restart the CM service (cloudera-scm-server) and then check the role status. If it still reports unknown health for the management host, then check the health alert and share the message here. In case of CM Server startup failure, please check the CM Server log on the host. The CM Server log would provide an insight to the cause of failure.

Thank you. I'll check again CM server logs.

Thank you everyone. My problem is just uuid file in line feed.
