Addressing a Bad file descriptor error in a Mac OS client log

When a Mac OS disk contains bad file descriptors and other errors, it may cause problems for the Identity Finder search. These issues can generally be resolved by using the built in Mac OS utility, Disk Utility.  Disk Utility can be launched by openining Applications and then Utilities and then double-clicking on Disk Utility.  Information on the specific files with issues is contained in the local Identity Finder client log file.  This information will help you determine which disk(s) to repair.

The repair process consists of two components: Verifying and Repairing Disk Permissions and Verifying and Repairing Disk

Repairing Permissions

  1. When first opened, a prompt is displayed to select a disk to analyze or repair.
  2. Select the hard drive that contains the file(s) with bad file descriptors.  Once selected, the Verify Disk Permissions button becomes enabled.
  3. Click the Verify Disk Permissions button to perform a permissions analysis.
  4. Once the process completes, the Repair Disk Permissions button will become enabled if errors were encountered.
  5. Click the Repair Disk Permissions button to repair the permissions.
  6. Move on to the section Repairing the Disk

Repairing Disk

  1. If the steps in Repairing Permissions above were completed, continue to step 2.  If those steps were not completed, perform steps 1 and 2 in that section.
  2. Click the Verify Disk button to perform a disk analysis.
  3. Once the process completes, the Repair Disk button will become enabled if errors were encountered.
  4. Click the Repair Disk button to repair the disk.
  5. Exit Disk Utility
