2. Reads the replica ring of each and every partition held by the server and checks whether all
servers in the replica ring are up and all the replicas are in the ON state.
3. Checks the time synchronization of all the servers in the replica ring. This shows the time
difference between the servers.
1.5.5 Categorization of Health
Based on the errors found while checking the health of a server, there can be the three categories of
health. The status of the health checks is logged in to a log file. For more information, refer to
Section 1.5.6, “Log Files,” on page 18.
The three categories of health Normal, Warning, and Critical.
Normal
The server health is normal when all the health checks were successful.
The upgrade proceeds without interruption.
Warning
The server health is in the warning category when minor errors are found while checking the health.
If the health check is run as part of the upgrade, you are prompted to either abort or continue.
Warnings normally occur in the following scenarios:
1. Server not listening on LDAP and HTTP ports, either normal or secure or both.
2. Unable to contact any of the nonmaster servers in the replica ring.
3. Servers in the replica ring are not in sync.
Critical
The server health is critical when critical errors were found while checking the health.
If the health check is run as part of the upgrade, the upgrade operation is aborted.
The critical state normally occurs in the following cases:
1. Unable to read or open the DIB. The DIB might be locked or corrupt.
2. Unable to contact all the servers in the replica ring.
3. Locally held partitions are busy.
4. Replica is not in the ON state.
1.5.6 Log Files
Every server health check operation, whether it is run with the upgrade or as a standalone utility,
maintains the status of the health in a log file.
The content of the log file is similar to the messages displayed on the screen when the checks are
happening.
