Files Are Not Truncated as Expected

Even if the truncation mintime requirement is met, files may not be truncated. Files are truncated only to keep the file system below the low-water mark (by default 75% of the capacity). When the daily truncation policies run, the oldest files are truncated first in an effort to bring the file system usage below the low-water mark. Thus, files may remain on disk even though their truncation mintime requirement has been met if the disk space is not required.

You can use the StorNext GUI to adjust the low-water and high-water marks on each file system if more free disk space is desired. A temporary option to free up disk space is to execute the following command:

The goal argument is a disk usage percentage. For example specifying -o 65 will truncate files until the disk usage either reaches 65% or there are no more valid truncation candidates, i.e. the mintime requirement has been satisfied.
