Phase Ib: Rescan For More Dup's; Phase 2 Check Pathnames - Sun Microsystems Sun Workstation 100U System Manager's Manual

Fsck Error Conditions Fsck - UNIX File System Checker
NO terminate the program.
DUP TABLE OVERFLOW (CONTINUE)
An internal table in
I,ck
containing duplicate block numbers has no more room. Recompile
I,ck
with a larger value of DUPTBLSIZE.
Possible responses to the CONTINUE prompt are:
YES
continue with the program. This error condition will not allow a complete check of the file
system. A second run of
I,ck
should be made to re-check this file system. If another dupli-
cate block is found, this error condition will repeat.
NO terminate the program.
PARTIALLY ALLOCATED INODE 1==1 (CLEAR)
Inode I is neither allocated nor unallocated.
Possible responses to the CLEAR prompt are:
YES
de-allocate inode I by zeroing its contents.
NO ignore this error condition.
INCORRECT BLOCK COUNT 1=1 (X should be Y) (CORRECT)
The block count for inode
1
is
X blocks, but should be Y
blocks. When preen'ing the count is
corrected.
Possible responses to the CORRECT prompt are:
YES
replace the block count of inode
1
with
Y.
NO ignore this error condition.
A.4. Phase 1B: Rescan tor More Dup's
When a duplicate block is found in the file system, the file system is rescanned to find the inode
which previously claimed that block. This section lists the error condition when the duplicate
block is found.
BDUPI=I
Inode 1 contains block number B that is already claimed by another inode. This error condition
will always invoke the BAD/DUP error condition in Phase 2. You can determine which inodes
have overlapping blocks by examining this error condition and the DUP error condition in
Phase
1.
A.5. Phase 2 - Check Pathnames
This phase concerns itself with removing directory entries pointing to error conditioned inodes
from Phase 1 and Phase 1 b. This section lists error conditions resulting from root inode mode
and status, directory inode pointers in range, and directory entries pointing to bad inodes. All
errors in this phase are fatal if the file system is being preen'ed.
