Phase 1: Check Blocks and Sizes Messages

This phase checks the inode list. It reports error conditions encountered while:

All errors in this phase except INCORRECT BLOCK COUNT, PARTIALLY TRUNCATED INODE, PARTIALLY ALLOCATED INODE, and UNKNOWN FILE TYPE terminate fsck when it is preening a file system.

These messages (in alphabetical order) might occur in phase 1:


block-number BAD I=inode-number
Cause

Inode inode-number contains a block number block-number with a number lower than the number of the first data block in the file system or greater than the number of the last block in the file system. This error condition might generate the EXCESSIVE BAD BLKS error message in phase 1 if inode inode-number has too many block numbers outside the file system range. This error condition generates the BAD/DUP error message in phases 2 and 4.

Action

N/A


BAD MODE: MAKE IT A FILE?
Cause

The status of a given inode is set to all 1s, indicating file system damage. This message does not indicate physical disk damage, unless it is displayed repeatedly after fsck -y has been run.

Action

Type y to reinitialize the inode to a reasonable value.


BAD STATE state-number TO BLKERR
Cause

An internal error has scrambled the fsck state map so that it shows the impossible value state-number. fsck exits immediately.

Action

Contact your local service provider or another qualified person.


fragment-number DUP I=inode-number

Oracle Solaris 10: 


block-number DUP I=inode-number
Cause

Inode inode-number contains a block number fragment-number, which is already claimed by the same or another inode. This error condition might generate the EXCESSIVE DUP BLKS error message in phase 1 if inode inode-number has too many block numbers claimed by the same or another inode. This error condition invokes phase 1B and generates the BAD/DUP error messages in phases 2 and 4.

Oracle Solaris 10: Inode inode-number contains a block number block-number, which is already claimed by the same or another inode. This error condition might generate the EXCESSIVE DUP BLKS error message in phase 1 if inode inode-number has too many block numbers claimed by the same or another inode. This error condition invokes phase 1B and generates the BAD/DUP error messages in phases 2 and 4.

Action

N/A


DUP TABLE OVERFLOW (CONTINUE)
Cause

fsck could not allocate memory to track duplicate fragments. If the -o p option is specified, the program terminates.

Oracle Solaris 10: There is no more room in an internal table in fsck containing duplicate block numbers. If the -o p option is specified, the program terminates.

Action

To continue the program, type y at the CONTINUE prompt. When this error occurs, a complete check of the file system is not possible. If another duplicate fragment is found, this error condition repeats. Increase the amount of virtual memory available (by killing some processes, increasing swap space) and run fsck again to recheck the file system. To terminate the program, type n.

Oracle Solaris 10: To continue the program, type y at the CONTINUE prompt. When this error occurs, a complete check of the file system is not possible. If another duplicate block is found, this error condition repeats. Increase the amount of virtual memory available (by killing some processes, increasing swap space) and run fsck again to recheck the file system. To terminate the program, type n.


EXCESSIVE BAD FRAGMENTS I=inode-number (CONTINUE)

Oracle Solaris 10: 


EXCESSIVE BAD BLOCKS I=inode-number (CONTINUE)
Cause

Too many (usually more than 10) fragments indicate an invalid disk address. If the -o p (preen) option is specified, the program terminates.

Oracle Solaris 10: Too many (usually more than 10) blocks have a number lower than the number of the first data block in the file system or greater than the number of the last block in the file system associated with inode inode-number. If the -o p (preen) option is specified, the program terminates.

Action

To continue the program, type y at the CONTINUE prompt. When this error occurs, a complete check of the file system is not possible. You should run fsck again to recheck the file system. To terminate the program, type n.


EXCESSIVE DUP BLKSDUPLICATE FRAGMENTS I=inode-number (CONTINUE)

Oracle Solaris 10: 


EXCESSIVE DUP BLKS I=inode-number (CONTINUE)
Cause

Too many (usually more than 10) fragments are claimed by the same or another inode or by a free-list. If the -o p option is specified, the program terminates.

Oracle Solaris 10: Too many (usually more than 10) blocks are claimed by the same or another inode or by a free-list. If the -o p option is specified, the program terminates.

Action

To continue the program, type y at the CONTINUE prompt. When this error occurs, a complete check of the file system is not possible. You should run fsck again to recheck the file system. To terminate the program, type n.


INCORRECT DISK BLOCK COUNT I=inode-number (number-of-BAD-DUP-or-missing-blocks
should be number-of-blocks-in-filesystem) (CORRECT)

Oracle Solaris 10: 


INCORRECT BLOCK COUNT I=inode-number (number-of-BAD-DUP-or-missing-blocks
should be number-of-blocks-in-filesystem) (CORRECT)
Cause

The disk block count for inode inode-number is incorrect.. When preening, fsck corrects the count.

Oracle Solaris 10: The block count for inode inode-number is number-of-BAD-DUP-or-missing-blocks, but should be number-of-blocks-in-filesystem. When preening, fsck corrects the count.

Action

To correct the disk block count of inode inode-number by number-of-blocks-in-file, type y at the CORRECT prompt. .

Oracle Solaris 10: To replace the block count of inode inode-number by number-of-blocks-in-filesystem, type y at the CORRECT prompt. To terminate the program, type n.


LINK COUNT TABLE OVERFLOW (CONTINUE)
Cause

There is no more room in an internal table for fsck containing allocated inodes with a link count of zero. If the -o p (preen) option is specified, the program exits and fsck has to be completed manually.

Action

To continue the program, type y at the CONTINUE prompt. If another allocated inode with a zero-link count is found, this error condition repeats. When this error occurs, a complete check of the file system is not possible. You should run fsck again to recheck the file system. Increase the virtual memory available by killing some processes or increasing swap space, then run fsck again. To terminate the program, type n.


PARTIALLY ALLOCATED INODE I=inode-number (CLEAR)
Cause

Inode inode-number is neither allocated nor unallocated. If the -o p (preen) option is specified, the inode is cleared.

Action

To deallocate the inode inode-number by zeroing out its contents, type y. This might generate the UNALLOCATED error condition in phase 2 for each directory entry pointing to this inode. To ignore the error condition, type n. A no response is appropriate only if you intend to take other measures to fix the problem.


PARTIALLY TRUNCATED INODE I=inode-number (SALVAGE)
Cause

fsck has found inode inode-number whose size is shorter than the number of fragments allocated to it. This condition occurs only if the system crashes while truncating a file. When preening the file system, fsck completes the truncation to the specified size.

Oracle Solaris 10: fsck has found inode inode-number whose size is shorter than the number of blocks allocated to it. This condition occurs only if the system crashes while truncating a file. When preening the file system, fsck completes the truncation to the specified size.

Action

To complete the truncation to the size specified in the inode, type y at the SALVAGE prompt. To ignore this error condition, type n.


UNKNOWN FILE TYPE I=inode-number (CLEAR)
Cause

The mode word of the inode inode-number shows that the inode is not a pipe, character device, block device, regular file, symbolic link, FIFO file, or directory inode. If the -o p option is specified, the inode is cleared.

Oracle Solaris 10: The mode word of the inode inode-number shows that the inode is not a pipe, special character inode, special block inode, regular inode, symbolic link, FIFO file, or directory inode. If the -o p option is specified, the inode is cleared.

Action

To deallocate the inode inode-number by zeroing its contents, which results in the UNALLOCATED error condition in phase 2 for each directory entry pointing to this inode, type y at the CLEAR prompt. To ignore this error condition, type n.
