Symptoms
This alert pertains to Dell Storage Manager (DSM) / Enterprise Manager (EM). It contains specific information related to system features and/or functionality.
Alert:
The database used in conjunction with DSM / EM may have its stats trim operation time out and the trim is not performed. As a result of this the database continues to grow in size as successive trim operations fail, eventually leading to out of space conditions.
The main symptom to recognizing the issue is the database growing very large in size due to DSM / EM being unable to delete the old data point.
To determine if you are encountering this issue, a query should be run against the database to find data entries that are past the Reporting Data retention period set within DSM / EM Data Collector Limits properties.
Affected versions:
Dell Storage Manager and Enterprise Manager versions prior to DSM 2018 R1
Cause
The larger quantity of storage systems reporting to a single Data Collector / database, the more likely the trim operation time out issue is to occur.
Resolution
Workaround:
Contact Dell Technical Support for further guidance on reducing the size of the database if this issue is already occurring.
The larger quantity of storage systems reporting to a single Data Collector / database, the more likely the trim operation time out issue is to occur. To assist in preventing the time out from occurring, reduce the Reporting Data Retention Period to 180 Days.
Resolution:
