Scheduling Example
You can use crontab for schedule file selection and relocation at specified intervals.
To schedule automatic relocations, run crontab to include an example such as the following
in a crontab file. The example crontab file entry selects files eligible for relocation and moves
them to destination component volumes. The relocation process occurs once every three days
at 12:30 A.M.
30 0 1,4,7,10,13,16,19,22,25,28 * * /opt/VRTS/bin/fssweep |
/opt/VRTS/bin/fsmove
The first two fields specify the time to run the job. 30 0 is 12:30 A.M.
The next field defines how often to run the process. The list of digits is the days of the month
on which to run. The first asterisk (*) specifies that the process runs every month.The second
asterisk specifies that days of the week are not used as criteria for when to run. See the
crontab(5) manual page for more information.
The last two fields specify the commands to run, which are the fssweep and fsmove
commands.
