Table 8-1 shows the tests you can perform with Linux FailSafe diagnostic commands:
Table 8-1. FailSafe Diagnostic Test Summary
Diagnostic Test | Checks Performed |
|---|---|
resource | Checks that the resource type parameters are set Check that the parameters are syntactically correct Validates that the parameters exist |
resource group | Tests all resources defined in the resource group |
failover policy | Checks that the failover policy exists Checks that the failover domain contains a valid list of hosts |
network connectivity | Checks that the control interfaces are on the same network Checks that the nodes can communicate with each other |
serial connection | Checks that the nodes can reset each other |
All transactions are logged to the diagnostics file diags_nodename in the log directory.
You should test resource groups before starting FailSafe HA services or starting a resource group. These tests are designed to check for resource inconsistencies which could prevent the resource group from starting successfully.
