dumpe2fs - dump filesystem information |
|

|
|

|

__dumpe2fs__ [[ __-bfhixV__ ] [[ __-ob__ |

!!DESCRIPTION |
|
|
23 |
|
|
|
24 |
|
|
|
25 |
__dumpe2fs__ prints the super block and blocks group |
|
|
26 |
information for the filesystem present on |
|
|
27 |
''device.'' |
|
|
28 |
|
|
|
29 |
|
|
|
30 |
__dumpe2fs__ is similar to Berkeley's __dumpfs__ |
|
|
31 |
program for the BSD Fast File System. |

!!OPTIONS |

|
|
|
35 |
__-b__ |
|
|
36 |
|
|
|
37 |
|
|
|
38 |
print the blocks which are reserved as bad in the |
|
|
39 |
filesystem. |
|
|
40 |
|
|
|
41 |
|
|
|
42 |
__-ob__ ''superblock'' |
|
|
43 |
|
|
|
44 |
|
|
|
45 |
use the block ''superblock'' when examining the |
|
|
46 |
filesystem. This option is not usually needed except by a |
|
|
47 |
filesystem wizard who is examining the remains of a very |
|
|
48 |
badly corupted filesystem. |
|
|
49 |
|
|
|
50 |
|
|
|
51 |
__-oB__ ''blocksize'' |
|
|
52 |
|
|
|
53 |
|
|
|
54 |
use blocks of ''blocksize'' bytes when examining the |
|
|
55 |
filesystem. This option is not usually needed except by a |
|
|
56 |
filesystem wizard who is examining the remains of a very |
|
|
57 |
badly corupted filesystem. |
|

|
|

__-f__ |
|
|
61 |
|
|
|
62 |
|
|
|
63 |
force dumpe2fs to display a filesystem even though it may |
|
|
64 |
have some filesystem feature flags which dumpe2fs may not |
|
|
65 |
understand (and which can cause some of dumpe2fs's display |
|
|
66 |
to be suspect). |
|
|
67 |
|
|
|

|
|
|
69 |
__-h__ |
|
|
70 |
|
|
|
71 |
|
|
|
72 |
only display the superblock information and not any of the |
|
|
73 |
block group descriptor detail information. |
|
|
74 |
|
|
|
75 |
|
|
|
76 |
__-i__ |
|
|
77 |
|
|
|
78 |
|
|
|
79 |
display the filesystem data from an image file created by |
|
|
80 |
__e2image__, using ''device'' as the pathname to the |
|
|
81 |
image file. |
|
|
82 |
|
|
|
83 |
|
|
|
84 |
__-x__ |
|
|
85 |
|
|
|
86 |
|
|
|
87 |
print the detailed group information block numbers in |
|
|
88 |
hexadecimal format |
|
|
89 |
|
|
|
90 |
|
|
|
91 |
__-V__ |
|
|
92 |
|
|
|
93 |
|
|
|
94 |
print the version number of __dumpe2fs__ and |
|
|
95 |
exit. |
|
|
96 |
!!BUGS |
|
|
97 |
|
|
|
98 |
|
|
|
99 |
You need to know the physical filesystem structure to |
|
|
100 |
understand the output. |
