The pdffsck command checks a HiRDB file system area for integrity errors and repairs any errors that are detected. If an inconsistency is detected, the command displays the corresponding file or area.
You should execute the pdffsck command when either of the following occurs:
The following table describes the integrity check items and repair methods:
Target | Check item | Cause | Repair method |
---|---|---|---|
HiRDB file | Whether or not there are unusable HiRDB files | Cancellation of file creation or deletion processing | Manages the files as being in unused status and the allocated area as free area. |
Area in a HiRDB file | Whether or not there is an area that is referenced neither from the free area list nor from the file management table | Cancellation of file extension (automatic extension) processing | Manages the isolated area as a free area. |
Management information in the HiRDB file system area | Inconsistent statistical information stored in the management area of the HiRDB file system area | Cancellation of file creation or deletion processing | Correct the information, such as file count statistical information, when each check is completed. |
Superuser or HiRDB administrator
pdffsck [-c] HiRDB-file-system-area-name |
Specifies that the HiRDB file system area is to be checked only. When the -c option is specified, the HiRDB file system area is not repaired.
Specifies the name of the HiRDB file system area.
When the KFPI21559-W message is displayed due to an inconsistency detected in the area, the applicable information item listed below is displayed, as appropriate for the detected inconsistency. If the KFPI21558-I message is displayed but no inconsistency was detected, the information below is not displayed.
An unusable HiRDB file is distinguished by the status of the area allocated to it, in terms of whether or not the area itself is usable. If the area is not usable, the command displays the name, start location, and size of every file in the area. Because the area may not be unusable for all the unusable files, the displayed unusable file count may not match the number of files that are listed.
unusable file count aa...a |
The start location and size of each unusable area is displayed. This information is displayed for all applicable areas. The displayed unusable area count always matches the number of areas that are listed.
unusable area count aa...a |
unusable file count aa...a |
