Re: Linux Kernel Networking document (free, 178 pages doc)
I took a minute to find the list of flags: Look for s_feature_incompat and s_feature_ro_compat at https://ext4.wiki.kernel.org/index.php/Ext4_Disk_Layout The incompat flags are of most interest for the discussion. If any of those are set, neither the ext2 nor the ext3 driver can mount the filesystem unless they have been extended to support these features: === Incompatible feature set. If the kernel or fsck doesn't understand one of these bits, it should stop. Any of: 0x1 Compression (INCOMPAT_COMPRESSION). 0x2 Directory entries record the file type. See ext4_dir_entry_2 below (INCOMPAT_FILETYPE). 0x4 Filesystem needs recovery (INCOMPAT_RECOVER). 0x8 Filesystem has a separate journal device (INCOMPAT_JOURNAL_DEV). 0x10Meta block groups. See the earlier discussion of this feature (INCOMPAT_META_BG). 0x40Files in this filesystem use extents (INCOMPAT_EXTENTS). 0x80Enable a filesystem size of 2^64 blocks (INCOMPAT_64BIT). 0x100 Multiple mount protection. Not implemented (INCOMPAT_MMP). 0x200 Flexible block groups. See the earlier discussion of this feature (INCOMPAT_FLEX_BG). 0x400 Inodes can be used for large extended attributes (INCOMPAT_EA_INODE). (Not implemented?) 0x1000 Data in directory entry (INCOMPAT_DIRDATA). (Not implemented?) 0x2000 Never used (INCOMPAT_BG_USE_META_CSUM). Probably free. 0x4000 Large directory >2GB or 3-level htree (INCOMPAT_LARGEDIR). 0x8000 Data in inode (INCOMPAT_INLINE_DATA). == Greg On Mon, Feb 4, 2013 at 8:49 AM, Greg Freemyer wrote: > (Why is this a top-posted message thread?

Re: Linux Kernel Networking document (free, 178 pages doc)
(Why is this a top-posted message thread? Please stop creating these.) Only the first link says that the ext2 driver can mount a ext4 filesystem (if the journal is clean). I'm confident that is wrong. Ext4 has several on-disk features that are not backward compatible. There is a binary set of flags which is set at mkfs time as to which of those features were enabled by mkfs.ext4. A ext3 doc would only describe a ext4 filesystem with all of those flags off. Thus a ext3 doc describing the on disk structure is not a waste of time, but it becomes a subset of a full ext4 doc describing the on disk structure. I would recommend that documenting that set of flags be the first documentation effort.

Re: Linux Kernel Networking document (free, 178 pages doc)
generally, anything u write for ext2, should still be valid for ext3, and ext4. in the sense that the features are backward compatible. sizing limits may have increased, but OLD working mechanism should still be validexcept for some. so ext2 fs should still be mountable as ext4, but not vice versa, once some flag is enabled (I think it is xattr). and if the flag is not enabled, and the journal logs is clean, then ext4 fs is also mountable as ext2 fs: http://superuser.com/questions/408822/ext4-converted-mounted-as-ext2 http://computer-forensics.sans.org/blog/2011/06/14/digital-forensics-mounting-dirty-ext4-filesystems http://en.wikipedia.org/wiki/Extended_file_attributes On Sun, Feb 3, 2013 at 12:26 AM, Rami Rosen wrote: > Hi, > > ext2 and ext3 are kind of obsolete now. > > Indeed, ext4 was integrated into Linux kernel back in 2008. > Amongs its known features which do not exist in ext3 are support for > huge files (like 1 EB (exabyte or somtimes termed exbibyte); 1 EB is > 1024 PB (petabyte) whereas > 1 PB is 1024 TB (terabyte). > a directory can contain a maximum of 64,000 subdirectories (whereas we > have 32,000 in ext3) > Amongst its other features are Journal checksumming, Multiblock > allocator, Faster file system checking and more. > > > If you prefer to start with simpler implementations, ext3 is of course > simpler, and of course ext2 is even simpler than ext3. > > But in case you intend to start with ext2/ext3, and later perform > a pass on all your documentation to update it to ext4, take into > consideration that this will take quite a time; depending on how deep > you intend to delve into implementation details. > > Good luck! > > Regards, > Rami Rosen > http://ramirose.wix.com/ramirosen > > > > On Sat, Feb 2, 2013 at 11:43 AM, Shubham Sharma > wrote: > > Hi, > > > > I understand that ext2 and ext3 are kind of obsolete now.

Re: Linux Kernel Networking document (free, 178 pages doc)
Hi, > ext2 and ext3 are kind of obsolete now. Indeed, ext4 was integrated into Linux kernel back in 2008. Amongs its known features which do not exist in ext3 are support for huge files (like 1 EB (exabyte or somtimes termed exbibyte); 1 EB is 1024 PB (petabyte) whereas 1 PB is 1024 TB (terabyte). a directory can contain a maximum of 64,000 subdirectories (whereas we have 32,000 in ext3) Amongst its other features are Journal checksumming, Multiblock allocator, Faster file system checking and more. If you prefer to start with simpler implementations, ext3 is of course simpler, and of course ext2 is even simpler than ext3. But in case you intend to start with ext2/ext3, and later perform a pass on all your documentation to update it to ext4, take into consideration that this will take quite a time; depending on how deep you intend to delve into implementation details.
