The Disk Full feature offers three levels of control over disk full checks:
The DISK_FULL_LIMIT keyword provides checking on all files.
The volume-specific limit overrides the system-wide limit.
The file-specific check overrides the system-wide and volume-specific checks.
If extending the size of the file would leave less than the specified threshold, then the write operation causing the file extension fails, returning SAVL_ERR (583).
Note the following issues related to this feature:
FairCom Servers that do not support this feature ignore the DISK_FULL_LIMIT keyword. This feature is currently limited to Windows and Unix platforms. (However, this changes over time, so check with your nearest FairCom office for current supported platforms.)
In non-server models, test the disk full condition by setting the global ULONG ct_disklmt to the threshold value.
In the bound server model, set the disk full threshold in the disklmt member of the configuration structure.
If a file is mirrored, the check is performed only for the primary file.
