How to follow the development of ext4-enabled e2fsprogs more closely via git? Does that make sense:
       $ git clone git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
       $ cd e2fsprogs
       $ git checkout -b pu
       Switched to a new branch "pu" 
       $ git branch 
       master
       * pu
       $ git pull git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git pu

:At this point I'd probably tell people to follow e2fsprogs via 'next' or 'master', since it's just much easier.  We told people to follow 'pu' because there were critically needed patches for ext4 that weren't quite ready to be locked down in stone.   But that's no longer necessary now, so for most users, 'master', or 'next' if they want to play with things a bit earlier than those who want something a little more conservative, is probably be best for all but the most die-hard ext4 developers.  --[[User:Tytso|Tytso]] 21:57, 14 July 2008 (UTC)

== about "tune2fs -I 256 /dev/DEV" ==

You may want to add info about that it can take a long time to convert inodesize (for me it have run for about 7 hours now on a 500 GB partition and has still not finished).
You may also want to add info about how dangerous for the filessytem it is, if you can abort it and similar information.

:Seven hours seems to be excessively long.   How long does it normally take to run fsck on your filesystem?  As long as you got a message indicating that the operation could be undone using the "e2undo command", it should be safe to interrupt the tune2fs -I and then running the indicated "e2undo command".  i.e., you should have seen something like this:

       # tune2fs  -I 256 /dev/thunk/testext4 
       tune2fs 1.41.1 (01-Sep-2008)
       To undo the tune2fs operations please run the command
           e2undo /var/lib/e2fsprogs/tune2fs-testext4.e2undo /dev/thunk/testext4

:It does require that the /var/lib/e2fsprogs directory exists.  You can also control the directory where the undo file will be stored by editing /etc/mke2fs.conf; see the man page for /etc/mke2fs.conf for more details.  Hope this helps...[[User:Tytso|Tytso]] 20:05, 29 September 2008 (UTC)
