7 DR Series Appliance Cleaner Best Practices
2 How to determine if the cleaner is keeping up
Dell recommends that a full cleaner pass compete once every 7 days or less. To determine if the cleaner
is keeping up, a quick inspection of the cleaner statistics ‘Last Completion time(s)’ variable is described
below.
2.1.1 Using the stats --cleaner command
The stats --cleaner command displays the current running cleaner progress and the amount of time
taken to complete its latest full pass. The ‘Last Completion time(s)’ value indicates that the cleaner is
keeping up when it is less than or equal to 7 days.
Note: If the cleaner is running and it is not reporting to reclaim space, that does not mean there is an
issue or problem with the cleaner. When cleaner is running, somecleaner phases do not reclaim data
space. Only when the cleaner is executing in phases 3 and 4 is space reclaimed and the ‘Estimated
Logical Bytes left’ is updated.
