2.6 NAME 33
• recall an older migrated generation of a file from FSE media to an arbitrary
location on a non–HSM file system,
• explicitly put a file on the migration candidate list for corresponding FSE
partition,
• unconditionally release an already migrated file on an HSM file system,
• trigger migration of files that are currently considered migration candidates
on particular FSE partition and trigger migration of files which were not
migrated because of some failed migration,
• trigger deletion of files from an HSM file system, which are covered by the
configured deletion policy in the belonging FSE partition configuration file.
Each FSE command communicates with the FSE system components through the
Management Interface (fse–mif). To execute an FSE command, the Management
Interface must be running. If the connection to the Management Interface fails,
check its status by running the fse status command. In case the Management
Interface is not running, start it with the fse start command.
After a successful command execution fsefile notifies the FSE administrator with
a suitable message, which is printed to the standard output stream (stdout). If
there was an error during the command execution, an appropriate error message
is printed to the standard error stream (stderr).
JOB PROGRESS MONITORING fsefile is able to receive messages from
Management Interface to give the user ability to monitor the progress of the com-
mand.
Monitoring is enabled by default and can be disabled by using the – –no–monitor
option.
When monitoring is enabled, fsefile command reports events and other relevant
information from the FSE processes as long as the job that fsefile has started is
running. After the job terminates, the command exits. If monitoring is disabled,
the command returns the control immediately after it has started a corresponding
job. In this case no information from the job is received, even in case of errors.
Monitoring can be canceled by pressing
∧
C in the shell where fsefile runs.
