Description:
Ext2 Filesystems Utilities 1.39 is boot software developed by Theodore Ts'o.
Ext2 Filesystem Utilities project (e2fsprogs) contain all of the standard utilities for creating, fixing, configuring , and debugging ext2 filesystems.
Here are some key features of "Ext2 Filesystems Utilities":
e2fsprogs, which consists of e2fsck, mke2fs, debugfs, dumpe2fs, tune2fs, and most of the other core ext2fs filesystem utilities.
dump, which will allow you to make backups of your ext2 filesystems. It uses a format which is compatible with the BSD dump and restore programs.
defrag, which will defragment your ext2 filesystem
ext2ed, which is a text/windows (curses) interface for examining and editing an ext2 filesystem. It unfortunately is limited to filesystems smaller than 2GB, and is heavily Intel byte order dependent, and has apparently been abandoned by its original author. (So for those people who were used to seeing ext2ed in older Linux distributions, and wondered where it went to, that's the explanation.)
It has been integrated into e2fsprogs version 1.28, but its limitations mean that it should only be used by developers who need to generate test cases.
FSDEXT2 --- A (read-only) ext2 filesystem driver for Windows 95, implemented as Windows 95 File System Driver (FSD). This driver is maintained by Peter van Sebille (pese@nlnwgfsc.origin.nl).
Ext2fsd, An ext2 filesystem driver for Windows NT/2K/XP. The most recent version has read-write support.
MountX, MacOS driver which allows you to mount ext2 filesystems (Linux and MkLinux) on the Macintosh.
Ext2 Filesystem Utilities project (e2fsprogs) contain all of the standard utilities for creating, fixing, configuring , and debugging ext2 filesystems.
What's New in This Release:
Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems between 231 and 232 blocks.
Change mke2fs to use /etc/mke2fs.conf as a configuration file to configure the filesystem features, blocksize, and inode_ratio for different filesystem types.
Mke2fs will now create filesystems hash trees and on-line resizing enabled by default, based on the new /etc/mke2fs.conf file.
The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
filesystem device node in exclusive mode to prevent accidents by system administrators. In the case of resize2fs and mke2fs, it will only use exclusive mode if the filesystem is not mounted.
Fixed a bug in mke2fs which caused it to to fail when creating the resize inode for large filesystems. (Addresses Debian Bug 346580)
When allocating space for the RAID filesystems with the stride parameter, mke2fs will now place each portion of the group's inode table right up after the superblock (if present) in order to minimize fragmentation of the freespace.
Speed up mke2fs and e2fsck by writing inode and block bitmaps more efficiently by writing the inode and block bitmaps in one pass, thus reducing the number of disk seeks required.
Add support for on-line resizing to resize2fs.
Fix blkid library so that logic to determine whether or not a device's cached information in /etc/blkid.tab needs to be verified or not doesn't get confused by a system clock which is insane (for example, if the battery is dead on a Macintosh running PPC Linux. (Addresses Red Hat Bug: 182188)
The blkid library will now store the UUID of the external journal used by ext3 filesystems, so that in the future, the userspace mount binary can use this to find the location of the external journal and pass this information to the kernel.
E2fsck will now consult a configuration file, /etc/e2fsck.conf to control how various options should be handled. See the e2fsck.conf man page for more details. (Addresses Debian Bug: 150295)
E2fsck now prints an explanatory message when delaying a filesystem check when the system is running on battery. (Addresses Debian Bug: 350306)
E2fsck will detect if the superblock's last mount field or last write field is in the future, and offer to fix if so. (Addresses Debian Bug 327580) These problems will be fixed automatically in preen mode since Debian's boot sequence bogusly doesn't set the time correctly until potentially very late in the bootup process, and this can cause false positives which will cause users' systems to fail to boot. (Addresses Debian Bugs 343662 and 343645)
E2fsck now checks to see if the superblock hint for the location of the external journal is incorrect, and if so, offer to update it. (Addresses Debian Bug: 355644)
Fix e2fsck from segfaulting on disconnected inodes that contain one or more extended attributes. (Addresses Debian Bug: 316736, 318463)
E2fsck will stop and print a warning if the user tries running a
read/write badblocks test on a read-only mounted root filesystem.
Fix a memory leak in e2fsck's error paths. (Thanks to Michael C. Thompson for pointing these out; they were originally found using Coverity.)
When resizing a file containing a filesystem, resize2fs will expand or truncate a file as necessary. (Addresses Debian Bug: 271607)
Resize2fs will now automatically determine the RAID stride parameter that had been used to create the filesystem, and use that for newly created block groups. The RAID stride parameter may also be manually specified on the command line using the new -S option to resize2fs.
Fix mke2fs so that it correctly creates external journals on
big-endian machines (such as a S/390).
Fix a bug in the e2p library which could cause dumpe2fs to (rarely) fail to print out the journal or hash seed UUID. (Thanks to Guillaume Chambraud for pointing this out.)
Dumpe2fs will now print the size of the journal (if present).
Fix debugfs's set_inode_field command so it can properly set the frag, fsize, uid_high, gid_high, and author fields in the inode instead of silently failing, and so that setting the i_size actually sets i_size correctly.
Add a new debugfs command, set_current_time, which sets fs->now so that regression test suites can repeatedly modify the filesystem's last_write fields.
Fix a bug in debugfs's icheck which would incorrectly report the owner of an extended attribute block.
Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a print a usage message when an illegal option character is given.
Fix debugfs's dump_unsued command on filesystems with a 64k blocksize so it won't core dump. (Addresses SourceForge bug 1424311)
Fix mklost+found so that it creates a full-sized directory on filesystems with larger block sizes.
Fix a file descriptor leak in blkid library.
Fix a display bug in "badblocks -sv" so that the done message properly clears the block number at the end of the test. (Addresses Debian Bug 322231)
Allow fractional percentages to the -m option in mke2fs and tune2fs (Addresses Debian Bug: 80205)
Use fstat/fstat64 in getsize.c if the the target is a regular file,
instead of attempting to do a binary search. Fix some fd leaks in error cases.
Add support for device mapper library to the blkid library to ensure that the "best" (i.e., leaf) device is probed by the blkid library.
Fix the blkid library so that it notices when an ext2 filesystem is upgraded to ext3.
Improve the blkid's library VFAT/FAT detection; it now understands labels stored in the root directory, and is more paranoid about checking the FAT superblock values.
Fixed a fd leak in the uuid library which was causing problems for the LVM tools. (Addresses Debian Bug: 345832)
Add support for the reiser4 and software suspend partitions to the blkid library. Also add support for extract the label from iso9660 filesystems.
Fix a compile_et bug which miscount the number of error messages if continuations are used in the .et file.
Add extra sanity checks to protect users from unusual cirucmstances where /etc/mtab may not be sane, by checking to see if the device is reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug 319002)
Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian Bug: 343149, 341911, 300871, 316604, 316782, 330789)
Fix use-after-free bug in e2fsck when finishing up the use of the e2fsck context structure.
Fixed spelling mistakes, typos, and otherwise clarified man pages and documentation. (Addresses Debian Bugs: 329859, 322188, 316811, 312515, 351268, 357951, 347295, 316040, 368392, 368393, 368394, 368179)
Fixed various Debian packaging issues --- see debian/changelog for details. (Addresses Debian Bugs 317862, 320389, 290429, 310950, 310428, 330737, 330736, 329074, 356293, 360046, 366017, 364516,
362544, 362970)
