When ext3 split from ext2, they essentially were the same file system. The magic number would have been different, but the file systems were otherwise the same. Since then, ext2 has been placed in maintenance mode and additional features have been added to ext3, some of which are incompatible. I view this as a *good thing*. Ext2 may not be able to read ext3 file systems, but ext3 can certainly read ext2 file systems. This is intended as an upgrade path, not to be be backward compatible with the old code. It is a superset of ext2. The old file system code remains stable for those who still want to use it, while the new file system code gets the new features. This is how it will also be with ext4. I'm not sure what problems you had when upgrading from ext2, but tune2fs - -j should have only changed the magic number and added a journal. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFFCW+nLPWxlyuTD7IRAi2CAJ9VcZRilCFntVs7B+bJGGCoPdeNhwCfdMuC oyIGzXYm4qIGgbucFpG3WJQ= =1aWY -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
