gpfs_prealloc() support to preallocate any bytes of an new created file without zero-out data

Most of recent AI workload saves raw data in cloud object storage. When GPU is going to training partial of raw data, these data will be loaded and saved in high performance file system, such as Storage Scale. In ADAS and some of other AI worklo...

Add option to `mmedquota -d -u <user>` to specify file system and fileset

Currently the `mmedquota -d -u <user>` command will revert all quotas owned by the user back to configured file system level default quotas or per fileset default user quota settings, across all file systems in the cluster. Today if a user h...

maximum number of inodes to be increased automatically once threshold 70 or 80 % is reached, instead of waiting until the number of preallocated inodes exceeds the configured MaxNumInodes

The number of preallocated inodes had reached approximately 90% of the configured MaxNumInodes. To avoid reaching the configured limit, we manually increased the maximum number of inodes to 2.5 million. We would like IBM Storage Scale to generate ...
