The journal keeps track of any changes that were being made - at the time the system crashed, and can ensure that your file system - is consistent without the need for a lengthy check. - - Other than adding the journal to the file system, the on-disk format - of ext3 is identical to ext2. It is possible to freely switch - between using the ext3 driver and the ext2 driver, as long as the - file system has been cleanly unmounted, or e2fsck is run on the file - system. - - To add a journal on an existing ext2 file system or change the - behavior of ext3 file systems, you can use the tune2fs utility ("man - tune2fs"). To modify attributes of files and directories on ext3 - file systems, use chattr ("man chattr"). You need to be using - e2fsprogs version 1.20 or later in order to create ext3 journals - (available at <http://sourceforge.net/projects/e2fsprogs/>). - - To compile this file system support as a module, choose M here: the - module will be called ext3. - -config EXT3_DEFAULTS_TO_ORDERED - bool "Default to 'data=ordered' in ext3" - depends on EXT3_FS - default y - help - The journal mode options for ext3 have different tradeoffs - between when data is guaranteed to be on disk and - performance. The use of "data=writeback" can cause - unwritten data to appear in files after an system crash or - power failure, which can be a security issue. However, - "data=ordered" mode can also result in major performance - problems, including seconds-long delays before an fsync() - call returns. For details, see: - - http://ext4.wiki.kernel.org/index.php/Ext3_data_mode_tradeoffs - - If you have been historically happy with ext3's performance, - data=ordered mode will be a safe choice and you should - answer 'y' here. If you understand the reliability and data - privacy issues of data=writeback and are willing to make - that trade off, answer 'n'. - -config EXT3_FS_XATTR - bool "Ext3 extended attributes" - depends on EXT3_FS - default y - help - Extended attributes are name:value pairs associated with inodes by - the kernel or by users (see the attr(5) manual page, or visit - <http://acl.bestbits.at/> for details). - - If unsure, say N. - - You need this for POSIX ACL support on ext3. - -config EXT3_FS_POSIX_ACL - bool "Ext3 POSIX Access Control Lists" - depends on EXT3_FS_XATTR - select FS_POSIX_ACL - help - Posix Access Control Lists (ACLs) support permissions for users and - groups beyond the owner/group/world scheme. - - To learn more about Access Control Lists, visit the Posix ACLs for - Linux website <http://acl.bestbits.at/>. - - If you don't know what Access Control Lists are, say N - -config EXT3_FS_SECURITY - bool "Ext3 Security Labels" - depends on EXT3_FS_XATTR - help - Security labels support alternative access control models - implemented by security modules like SELinux.
