The following actions occur after a successful failover:
•
If Statstool processes were running before the failover, they are restarted. If the processes
were not running, they are not restarted.
•
The Statstool passive management console is installed on the StoreAll Fusion Manager in
maintenance mode.
•
Setrsync
is run automatically on all cluster nodes from the current active Fusion Manager.
•
Loadfm
is run automatically to present all file system data in the cluster to the active Fusion
Manager.
•
The stored cluster-level database generated before the Fusion Manager failover is moved to
the current active Fusion Manager, allowing you to request reports for the specified range if
pre-generated reports are not available under the Hourly, Daily and Weekly categories. See
“Generating reports” (page 111)
.
NOTE:
If the old active Fusion Manager is not available (pingable) for more than two days,
the historical statistics database is not transferred to the current active Fusion Manager.
•
If configurable parameters were set before the failover, the parameters are retained after the
failover.
Check the
/usr/local/ibrix/log/statstool/stats.log
for any errors.
NOTE:
The reports generated before failover will not be available on the current active Fusion
Manager.
Checking the status of Statistics tool processes
To determine the status of Statistics tool processes, run the following command:
#/etc/init.d/ibrix_statsmanager status
ibrix_statsmanager (pid 25322) is running...
In the output, the
pid
is the process id of the “master” process.
Controlling Statistics tool processes
Statistics tool processes on all file serving nodes connected to the active Fusion Manager can be
controlled remotely from the active Fusion Manager. Use the
ibrix_statscontrol
tool to start
or stop the processes on all connected file serving nodes or on specified hostnames only.
•
Stop processes on all file serving nodes, including the Fusion Manager:
# /usr/local/ibrix/stats/bin/ibrix_statscontrol stopall
•
Start processes on all file serving nodes, including the Fusion Manager:
# /usr/local/ibrix/stats/bin/ibrix_statscontrol startall
•
Stop processes on specific file serving nodes:
# /usr/local/ibrix/stats/bin/ibrix_statscontrol stop <hostname1>
<hostname2> ..
•
Start processes on specific file serving nodes:
# /usr/local/ibrix/stats/bin/ibrix_statscontrol start <hostname1>
<hostname2> ..
