Add quota logging capability to keep overall quota accounting consistent

For performance, nowadays, most of quota information is stored and updated in memory. Then, it will be synced back to disk in an asynchronous way later. However, there isn't a recovery mechanism for GPFS quota in abnormal situations. These can make quota usage inaccurate in below situations: - Failures of hardware environment, such as network interruptions, power failures and panic of a node etc. - In a large cluster, there are always a few nodes which will be expelled nearly every day. For this kind of configuration, it is normal and can be accepted, however, GPFS quota module can't offer an accurate usage in this situation. Especially for HPC performance is important. Adding this kind of logging capability to the quota accounting should also come along with less performance penalty.

    The requirement have been delivered by different means.

    In recent IBM Storage Scale releases, quota improvements have focused on performance, scalability, and reliability, rather than adding new logging or auditing features. We delivered faster quota processing for large fileset deletions, improved concurrency and scalability for quota checks across multiple filesets, and increased accuracy under heavy workloads. Internal locking and accounting enhancements reduced contention and corrected discrepancies seen during active I/O and deletion scenarios. We also added support for very small quotas, enabling better behavior for containerized and backup/restore use cases.

    Please create a new RFE and or support ticket, in case you identify gaps in the quota handling of the latest Scale 6.0.0 release.

    Thank you for submitting this enhancement request. This is not in the Storage Scale roadmap in the foreseeable future.

    We frequently see wrong quotas on our HPC system. Any improvement which helps to debug and fix these issues is greatly appreciated.
