then your application shouldn't get enospc error. I would suggest
you to look into your application for why it reports "out of disk
space" error.<br>
<br>
As for poor write speed, I guess your file system might be
fragmented heavily. Umount and remount your file system with mount
option "-o localalloc=4" If 4 didn't help then go down to 2 and see
if that helps.<br>
<br>

<div>Hi.<br>
<br>
</div>
I'm using ocfs2 device with two nodes of
500Gb and I have 350Gb free. Everything
works fine. However I always recieve "out
of disk space" error in my web application
and some performance problems because of
that. <br>
<br>
</div>
I know that this can be fixed by turning on
<span style="font-family:Courier New">discontig-bg
feature but I've already done that and it
didn't help. <br>
</span></div>
<div><span style="font-family:Courier New">Then
I saw that this feature is incompatible
for my device:<br>
