E2fsprogs 1.16 (October 22, 1999)
|
||||
=================================
|
||||
|
||||
Fixed a race condition bug in fsck; when printing a progress bar, if
|
||||
checking multiple filesystems in parallel, it was possible for fsck to
|
||||
send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
|
||||
handler, which would cause it to terminate with a signal 10.
|
||||
|
||||
E2fsck now properly handles filesystems that have the
|
||||
INCOMPAT_FILETYPE feature turned on. It can be used to convert a
|
||||
filesystem into using or not using FILETYPE feature.
|
||||
|
||||
E2fsck now properly handles filesystems that have the IMAGIC feature
|
||||
turned on (this is used on Linux AFS servers).
|
||||
|
||||
The mke2fs program now creates filesystems that have the filetype and
|
||||
sparse_superblock features enabled by default, unless it is run on a
|
||||
pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
|
||||
so there is now a new flag -O which allows the user to specify with
|
||||
which features she would like to create the filesystem; "mke2fs -O
|
||||
none" will create a filesystsem compatible with 2.0 kernels.
|
||||
|
||||
The tune2fs program now has a -O option which allows the user to set
|
||||
and reset "safe" filesystem features. Currently, the only ones which
|
||||
allows to be modified are the filetype and sparse_superblock features.
|
||||
Note setting or clearing either feature will require running e2fsck on
|
||||
the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
|
||||
requires that there is enough free space on the filesystem for the
|
||||
extra superblocks which will be created by e2fsck.)
|
||||
|
||||
Debugfs can now set and print filesystem features in the superblock
|
||||
using the "features" command. Dumpe2fs will print out the complete
|
||||
set of features when listing the superblock.
|
||||
|
||||
Dumpe2fs has new options -f (force) and -h (header-only).
|
||||
|
||||
Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
|
||||
message to come up. This could happen when decrementing or
|
||||
incrementing a link count could result in an overflow.
|
||||
|
||||
Fixed a bug in e2fsck where the block count on the lost+found
|
||||
directory would not be properly incremented when the directory was
|
||||
expanded to the point where an indirect block needed to be allocated.
|
||||
|
||||
E2fsck now makes some additional sanity checks on the superblock to
|
||||
avoid crashing or giving a memory allocation error if some of the
|
||||
values in the superblock are unresonable (but the superblock otherwise
|
||||
looks valid).
|
||||
|
||||
Fixed a bug in e2fsck where a very badly corrupted filesystem might
|
||||
require two passes to completely fix the filesystem. This happened if
|
||||
an inode claimed blocks that was part of the filesystem metadata
|
||||
(typically, when garbage was written into an inode table or indirect
|
||||
block, since this kind of filesystem corruption normally doesn't
|
||||
happen otherwise).
|
||||
|
||||
On the Alpha, glibc declares st_flags although it isn't actually used;
|
||||
the configure script was improved to detect this case so that
|
||||
e2fsprogs can avoid using the non-functional stat field.
|
||||
|
||||
The manual pages were updated to use a more consistent formatting
|
||||
style consistent with standard Unix man pages. Mke2fs's man page
|
||||
added documentation for a few previously undocumented options.
|
||||
|
||||
Fixed minor display bugs in tune2fs and mke2fs.
|
||||
|
||||
Programmer's notes:
|
||||
-------------------
|
||||
|
||||
Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
|
||||
|
||||
Added features to parse and print feature strings into the e2p library.
|
||||
(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
|
||||
|
||||
ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
|
||||
whose directory entries contain proper filetype information if the
|
||||
filesystem supports it.
|
||||
|
||||
ext2fs_link() now uses the low 3 bits of its flags parameter to pass
|
||||
the directory entry filetype information. This is used to set the
|
||||
directory entry filetype information if the filesystem supports it.
|
||||
|
||||
Fixed a bug in ext2fs_expand_dir() where the block count in a
|
||||
directory's inode would not be properly incremented when the directory
|
||||
was expanded to the point where an indirect block needed to be
|
||||
allocated.

Mke2fs now creates revision 1 filesystems by default, and with the

This package includes a number of utilities for creating, checking,
|
||||
and repairing ext2 filesystems.
|
||||
The e2fsprogs package contains a number of utilities for creating,
|
||||
checking, modifying and correcting any inconsistencies in second
|
||||
extended (ext2) filesystems. E2fsprogs contains e2fsck (used to repair
|
||||
filesystem inconsistencies after an unclean shutdown), mke2fs (used to
|
||||
initialize a partition to contain an empty ext2 filesystem), debugfs
|
||||
(used to examine the internal structure of a filesystem, to manually
|
||||
repair a corrupted filesystem or to create test cases for e2fsck), tune2fs
|
||||
(used to modify filesystem parameters) and most of the other core ext2fs
|
||||
filesystem utilities.
|
||||
|
||||
You should install the e2fsprogs package if you are using any ext2
|
||||
filesystems (if you're not sure, you probably should install this
|
||||
package).
