Phase 5: Check Cylinder Groups Messages

This sections contains phase 5 fsck messages in the Solaris 10 initial 3/05 release.

This phase checks the free-block and used-inode maps. It reports error conditions resulting from:

• Allocated inodes missing from used-inode maps

• Free blocks missing from free-block maps

• Free inodes in the used-inode maps

• Incorrect total free-block count

• Incorrect total used inode count

These messages (in alphabetical order) might occur in phase 5:

BLK(S) MISSING IN BIT MAPS (SALVAGE)

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.
