How to reclaim space manually in PureDisk

 
1. Expire all NetBackup images backed up to the PDDO storage pool
2. Check the Dedupe Storage queue folder. You should see lots of tlogs ready for processing
        ls -l /Storage/queue/
3. Run CR queue processing.
        /opt/pdcr/bin/crcontrol --processqueue
4. Monitor processing progress by checking the storage log
        tail -f /Storage/log/spoold/storaged.log
5. Run PDDO data removal and wait for 5 minutes (or you can check the job run status in the PD GUI)
         /opt/pdag/bin/php /opt/pdspa/workflowengine/createJobs.php -p 15
6. Run Garbage collection
        /opt/pdcr/bin/crcollect -v -m +1,+2
7. Check the Dedupe Storage queue folder. If you see some tlogs for processing, repeat steps 3 through 6.
8. Check the "used" and "Space available within containers" values in the following command
        /opt/pdcr/bin/crcontrol --dsstat
9. If dsstat showed a high value for "Space needs compaction", run compaction processing.
        /opt/pdcr/bin/crcontrol --compactstart
 
Note:  You will need to run steps 3-6 multiple times until there are 0 tlogs found when running:
 ls -l /Storage/queue/
