Kernel Messages
This appendix contains a listing of diagnostic or error messages generated by the VERITAS
File System (VxFS) kernel. Each message has a description and a suggestion on how to
handle or correct the underlying problem.
The following topics are covered in this chapter:
• File System Response to Problems
— Marking an Inode Bad
— Disabling Transactions
— Disabling a File System
— Recovering a Disabled File System
• Kernel Messages
— Global Message IDs
File System Response to Problems
When the file system encounters problems, it responds in one of three ways:
• Marks an inode bad
• Disables transactions
• Disables the file system
Marking an Inode Bad
Inodes can be marked bad if an inode update or a directory-block update fails. In these types
of failures, the file system does not know what information is on the disk, and considers all
the information that it finds to be invalid. After an inode is marked bad, the kernel still
permits access to the file name, but any attempt to access the data in the file or change the
inode fails.
