FILESYS-X-507: Invalid directory FAT chain. Volume name was NOT mounted.
Source: FILESYS.NLM
Explanation: A File Allocation Table (FAT) chain is a list of directory block locations. There are duplicate extended directory chains (chain0 and chain1). If these chains do not match for some reason, this error is produced and the volume will not mount.
Possible Cause: This error probably indicates file system corruption.
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.
