<br>This argument could have been important in March 2012, the month the ext4 change as applied. Today, March 2013, or Gluster devs decides to assume it's incompatible with ext4 and states it clearly in it's installations and migration documentation, or fixes it's current issues with ext4. No matter what is done, it should have been done months ago.<br>

I know where this statement came from. I believe you are both:<br><ul><li>trying to apply some statement on a context it's not pertinent to and <br></li></ul></blockquote><br></div>No, it's actually quite applicable. I'm aware of the context of that statement by Linus, and it applies to this case. Kernel devs, at least the ext4 maintainers, are being hypocritical. <br>
<br>There were a few exchanges between Ted T'so and Avati, among other people, on gluster-devel. I highly recommend you read them: <br><a href="http://lists.nongnu.org/archive/html/gluster-devel/2013-02/msg00050.html" target="_blank">http://lists.nongnu.org/archive/html/gluster-devel/2013-02/msg00050.html</a><div>

</ul></blockquote><br></div>This is probably true. I'm *this* close to declaring that, at least for the Gluster community, ext4 is considered harmful. There's a reason Red Hat started pushing XFS over ext4 a few years ago. <br>
<br>And Red Hat isn't alone here. <br><div><br><blockquote style="padding-left:5px;font-size:12pt;font-style:normal;margin-left:5px;font-family:Helvetica,Arial,sans-serif;text-decoration:none;font-weight:normal;border-left:2px solid rgb(16,16,255)">
The ext4 hash size change was applied in the kernel an year ago. I don't believe it will be undone. Gluster developers could argue that this change was hard on them, and that it shouldn't be backported to Enterprise kernels but after one year not having fixed it is on Gluster developers. Arguing otherwise seems rather foolish to me.<br>
</blockquote><br></div>I think that's a legitimate argument to make. This is a conversation that is worth taking up on gluster-devel. But I'm not sure what can be done about it, seeing as how the ext4 maintainers are not likely to make the change. <br>
<br>Frankly, dropping ext4 as an FS we can recommend solves a lot of headaches. <br><span><font color="#888888"><br>-JM<br><br><br></font></span></div></div></blockquote></div><br><br>
