FailSafe maintains system logs for each of the FailSafe daemons. You can customize
the system logs according to the level of logging you wish to maintain. For information on setting up log configurations, see Section 5.6. Log messages can be of the following types: - Normal
Normal messages report on the successful completion of a task. An example
of a normal message is as follows: Wed Sep 2 11:57:25.284 <N ha_gcd cms 10185:0>
Delivering TOTAL membership (S# 1, GS# 1) |
- Error/Warning
Error or warning messages indicate that an error has occurred or may
occur soon. These messages may result from using the wrong command or improper
syntax. An example of a warning message is as follows: Wed Sep 2 13:45:47.199 <W crsd crs 9908:0
crs_config.c:634> CI_ERR_NOTFOUND, safer - no
such node |
- Syslog Messages
All normal and error messages are also logged to syslog.
Syslog messages include the symbol <CI> in the header
to indicate they are cluster-related messages. An example of a syslog message
is as follows: Wed Sep 2 12:22:57 6X:safe syslog: <<CI>
ha_cmsd misc 10435:0> CI_FAILURE, I am not part
of the enabled cluster anymore |
- Debug
Debug messages appear in the log group file when the logging level is
set to debug0 or higher (using the GUI) or 10 or higher (using the CLI). Note: Many megabytes of disk space can be consumed on the server when debug
levels are used in a log configuration.
Examining the log files should enable you to see the nature of the system
error. Noting the time of the error and looking at the log files to note the
activity of the various daemons immediately before error occurred, you may
be able to determine what situation existed that caused the failure.
