This is an ALPHA release of a new, rewritten e2fsck. It is
|
|
significantly faster than the original e2fsck, particularily for systems
|
|
with large disks and a small buffer cache. This is because the
|
|
algorithms used in the original e2fsck are inefficient, and requires
|
|
multiple rereading of various directory and inode blocks.
|
|
|
|
This new e2fsck is based upon a ext2fs library which can be used by
|
|
other programs that need to access an ext2fs filesystem directly via the
|
|
device file, instead of through the kernel.
|
|
|
|
The debugfs program is a sample program which also uses the ext2fs
|
|
library. In addition, it can be used by a user to manually fix (or
|
|
corrupt) an ext2fs.
|
|
|
|
For the moment, please only use it if you are prepared to manually
|
|
descramble your filesystem if e2fsck screws up. It should be
|
|
relatively safe to use in "preen" mode (-p or -a), since it will abort
|
|
if it finds any really unusual situations. You will then have to run
|
|
e2fsck on that partition by hand.
|
|
|
|
If you find any bugs, please send them to me (tytso@mit.edu). Good luck!
