Cause

A cylinder group block map is missing some free blocks. During preening, fsck reconstructs the maps.

Action

To reconstruct the free-block map, type y at the SALVAGE prompt. To ignore this error condition, type n.

CG character-for-command-option: BAD MAGIC NUMBER

Cause

The magic number of cylinder group character-for-command-option is wrong. This error usually indicates that the cylinder group maps have been destroyed. When running interactively, the cylinder group is marked as needing reconstruction. fsck terminates if the file system is being preened.

Action

If this occurs, contact your local service provider or another qualified person.

FREE BLK COUNT(S) WRONG IN SUPERBLK (SALVAGE)

Cause

The actual count of free blocks does not match the count of free blocks in the superblock of the file system. If the -o p option was specified, the free-block count in the superblock is fixed automatically.

Action

To reconstruct the superblock free-block information, type y at the SALVAGE prompt. To ignore this error condition, type n.

SUMMARY INFORMATION BAD (SALVAGE)

Cause

The summary information is incorrect. When preening, fsck recomputes the summary information.

Action

To reconstruct the summary information, type y at the SALVAGE prompt. To ignore this error condition, type n.

Cleanup Phase Messages

Once a file system has been checked, a few cleanup functions are performed. The cleanup phase displays the following status messages.

number-of files, number-of-files
used, number-of-files free (number-of frags, number-of blocks, 
percent fragmentation)

This message indicates that the file system checked contains number-of files using number-of fragment-sized blocks, and that there are number-of fragment-sized blocks free in the file system. The numbers in parentheses break the free count down into number-of free fragments, number-of free full-sized blocks, and the percent fragmentation.

***** FILE SYSTEM WAS MODIFIED *****

This message indicates that the file system was modified by fsck. If this file system is mounted or is the current root (/) file system, reboot. If the file system is mounted, you might need to unmount it and run fsck again; otherwise, the work done by fsck might be undone by the in-core copies of tables.

filename FILE SYSTEM STATE SET TO OKAY

This message indicates that file system filename was marked as stable. Use the fsck -m command to determine if the file system needs checking.

filename FILE SYSTEM STATE NOT SET TO OKAY

This message indicates that file system filename was not marked as stable. Use the fsck -m command to determine if the file system needs checking.
