•
The

or the

options without

run
the clean operation once a week.
•
The
never
option turns off the
clean
process. Set a schedule using any of the other options
to turn on the
clean
process.
filesys clean set schedule [weekly | monthly | never]
[
day1 [, day2 ,...]][ time ]
For example, to run the operation automatically every Tuesday at 4 p.m, use either of the following
two commands.:
# filesys clean set schedule tue 1600
# filesys clean set schedule weekly tue 1600
The most recent invocation of the scheduling operation cancels the previous setting. To run the
operation more than once in a time period, set multiple days in one command. For example, to run
the operation on the first and fifteenth of the month at 4 p.m.:
# filesys clean set schedule monthly 1,15 1600
Set the Schedule or Throttle to the Default
To set the
clean
schedule to the default of Tuesday at 6 a.m. (tue 0600), the default throttle of
100%, or both, use the
filesys clean reset
operation. The operation is available only to
administrative users.
filesys clean reset {schedule | throttle | all}
Set the Run Time or Gigabytes Cleaned
To set the scheduled
clean
operation to run for a given time, until a given number of gigabytes
are available for data storage, or until the maximum of 25% of space available for data is cleaned,
use the
filesys clean set amount
operation. By default, the scheduled
clean
operation
cleans 25% of space available for data. Note that cleaning an entire full file system requires running
the clean operation four times at the default of 25%. Each operation takes two to four hours.
Administrative users only.
Data Domain recommends leaving the clean process at the default setting of 25%. With the default,
scripts that start cleaning do not need changing when the amount of data in the file system
increases. After the clean process runs four times at 25%, the whole file system has been processed.
Setting hours to the amount displayed as recommended time for cleaning now with the
filesys
clean show recommended
command returns a warning that when the file system is full, the
time needed for cleaning increases.
You can set the
hrs
and
GB-free
options in one command. With two options set, whichever
limit the operation reaches first stops the operation.
