|
|
|
|
.B e2fsck
|
2002-08-17 21:32:21 +04:00
|
|
|
is used to check a Linux second extended file system (ext2fs).

.B E2fsck

|
|
also
|
2000-08-14 18:25:19 +04:00
|
|
|
supports ext2 filesystems countaining a journal, which are
|
2002-08-17 21:32:21 +04:00
|
|
|
also sometimes known as ext3 filesystems, by first applying the journal
|
|
|
|
to the filesystem before continuing with normal
|
|
|
|
.B e2fsck
|
|
|
|
processing. After the journal has been applied, a filesystem will
|
|
|
|
normally be marked as clean. Hence, for ext3 filesystems,
|
|
|
|
.B e2fsck
|
|
|
|
will normally run the journal and exit, unless its superblock
|
|
|
|
indicates that further checking is required.

.IR superblock .
|
|
|
|
This option is normally used when the primary superblock has been
|
1999-11-23 16:57:16 +03:00
|
|
|
corrupted. The location of the backup superblock is dependent on the
|
|
|
|
filesystem's blocksize. For filesystems with 1k blocksizes, a backup
|
|
|
|
superblock can be found at block 8193; for filesystems with 2k
|
2001-05-02 00:01:08 +04:00
|
|
|
blocksizes, at block 16384; and for 4k blocksizes, at block 32768.
|
|
|
|
.IP
|
|
|
|
Additional backup superblocks can be determined by using the
|
|
|
|
.B mke2fs
|
|
|
|
program using the
|
|
|
|
.B \-n
|
|
|
|
option to print out where the superblocks were created. The
|
|
|
|
.B \-b
|
|
|
|
option to
|
|
|
|
.BR mke2fs ,
|
|

which specifies blocksize of the filesystem must be specified in order
|
|
|

for the superblock locations that are printed out to be accurate.

|
If an alternative superblock is specified and
|
1998-02-01 03:16:40 +03:00
|
|
|
the filesystem is not opened read-only, e2fsck will make sure that the
|
|
|
|
primary superblock is updated appropriately upon completion of the
|
|
|
|
filesystem check.

Normally,

|

|
|
will search for the superblock at various different
|
|
|
|
block sizes in an attempt to find the appropriate block size.
|
|
|
|
This search can be fooled in some cases. This option forces
|
|
|
|
.B e2fsck
|
|
|
|
to only try locating the superblock at a particular blocksize.
|
|
|
|
If the superblock is not found,
|
|
|
|
.B e2fsck
|

Please include as much information as possible in your bug report.

Ideally, include a complete transcript of the
|
|
|
|
.B e2fsck
|
|
|
|
run, so I can see exactly what error messages are displayed. If you
|
|
|
|
have a writeable filesystem where the transcript can be stored, the
|
|
|
|
.BR script (1)
|
|
|
|
program is a handy way to save the output of
|
1997-05-09 07:06:31 +04:00
|
|
|
.B e2fsck
|
1997-04-26 17:34:30 +04:00
|
|
|
to a file.

|

It is also useful to send the output of
|
|
|
|
.BR dumpe2fs (8).

|
If a specific inode or inodes seems to be giving
|
|
|
|
.B e2fsck
|
|
|
|
trouble, try running the
|
|
|
|
.BR debugfs (8)
|
|
|
|
command and send the output of the
|
1997-05-09 07:06:31 +04:00
|
|
|
.BR stat (1u)
|
|
|
|
command run on the relevant inode(s). If the inode is a directory, the
|
|
|
|
.B debugfs
|
1997-04-26 17:34:30 +04:00
|
|
|
.I dump
|
|
|
|
command will allow you to extract the contents of the directory inode,
|
|
|
|
which can sent to me after being first run through
|
|
|
|
.BR uuencode (1).

Always include the full version string which
|
|
|
|
.B e2fsck
|
|
|
|
displays when it is run, so I know which version you are running.
