Parameters

Impact on the System

System functions are unavailable.

Possible Causes

The user has manually modified the file permission, user information, or user groups, or the system has experienced an unexpected power-off.

Procedure

1. Check the file permission.
   1. Go to the MRS cluster details page and choose Alarms.
   2. In the details of the alarm, query the HostName (name of the alarmed host) and PathName (path or name of the involved file).
   3. Log in to the alarmed node.
   4. Run the ll PathName command to query the current user, permission, and user group of the file or path.
   5. Go to the ${BIGDATA_HOME}/nodeagent/etc/agent/autocheck directory and run the vi keyfile command. Search for the name of the involved file and query the correct permission of the file.
   6. Compare the actual permission of the file with the permission obtained in 1.e. If they are different, change the actual permission, user information, and user group to the correct values.
   7. Wait until the next system check is complete and check whether the alarm is cleared.
      • If yes, no further action is required.
      • If no, go to 2.

2. Collect fault information.
   1. On MRS Manager, choose System > Export Log.
   2. Contact the O&M engineers and send the collected logs.
