On PureDisk 6.6.3a and Deduplication Appliance 220.127.116.11, the PDDO Data Removal process is not present in cron on non-SPA nodes.
This can prevent data from being expire and result in full storage conditions.
Full storage partitions on PDDO-enabled storage pools with multiple nodes and an empty /Storage/log/PDDODataRemoval.log on all nodes.
Work around is to manually add the PDDO Data Removal script to cron on all non-SPA nodes.
- Login to the storage pool node, using the root account*
- Execute "crontab -l" and verify that PDDODataRemoval.php is not in cron
- Execute "crontab -e" to edit the cron entries
- Add the following line at the end of the crontab:
15 */2 * * * /opt/pdag/bin/php /opt/pdmbe/cli/PDDODataRemoval.php >>/Storage/log/PDDODataRemoval.log 2>&1
- Exit with ":wq" to save
- Execute "crontab -l" to verify the new entry is correctly added
* For NBU50x0 appliances, use these steps to login a root:
- Login to CLISH using 'sysadmin' account
- Navigate to Support -> Maintenance
- Type "elevate" to get root access
All these conditions must be met to be impacted:
- Version PD 6.6.3a / DD APP 18.104.22.168 or above;
- PDDO-enabled storage pool;
- Have multiple Metabase Engine nodes;
- The PDDO data selection tables must be on a Metabase Engine that is not on the SPA node
