<p>Hi Krutika,</p>
<p>Thanks for the info. <br>
</p>
<p>After a long time the preallocated disk has been created
properly. It was a 1TB disk on a hdd pool so a bit of delay was
expected. <br>
</p>
<p>But it took a bit longer then expected. The disk had no other
virtual disks on it. Is there something I can tweak or check for
this?</p>
<p>Regards, Jorick<br>

<div>Regarding the preallocated disk creation issue, could you
check if there are any errors/warnings in the fuse mount logs
(these are named as the hyphenated mountpoint name followed by
a ".log" and are found under /var/log/glusterfs).</div>

<p>Hi,</p>
<p>I have the similar issues with ovirt 4.2 on a
glusterfs-3.8.15 cluster. This was a new volume and I
created first a thin provisioned disk, then I tried to
create a preallocated disk but it hangs after 4MB. The
only issue I can find in the logs sofar are the [File
exists] errors with the sharding.<br>
