Explanation:  A File Allocation Table (FAT) chain is a list of directory block locations. If the FAT chain skips a block, a hole appears in the chain. (A hole is a section that is not sequential.) A hole indicates that the location was never allocated.

Action:  Run VREPAIR and restart the system.

Warning: If you delete the volume, all data will be destroyed. You will have to restore the data from a backup.

If the problem persists, make sure a volume backup exists. Delete the volume, re-create it, and restore the data from the backup.
