Hi Jaime,
<div><br>
</div>
<div>sorry for my late reply.</div>
<div><br>
</div>
<div>We identified the problem - the snapshot which was created was too small. It seems that the "SIZE" attribute was ignored.</div>
<div>The COW-table size was at 512MB which is the default.</div>
<div><br>
</div>
<div>We fixed this problem by adjusting the default value in the driver configuration.</div>
<div><br>
</div>
<div>Cheers!</div>
<div><br>
</div>

<div>Could it be that you don't have rw access to the image? Can you double-check your permissions?</div>
<div><br>
</div>
<div>ls -l $(readlink -f /var/lib/one/datastores/0/<VM_ID>/disk.0)</div>
<div><br>
</div>
<div>take a look at the group attribute of that block device. Can oneadmin read/write it? If that's not the case you'll probably need to</div>
<div><br>
</div>
<div>gpasswd -a oneadmin <block_device_group></div>
<div><br>
</div>
<div>BTW: I'm taking notice of this to reflect it in the documentation</div>

<div>cheers<br>

Hi,<br>
<br>
we are experiencing trouble when using OpenNebula with KVM, LVM on CentOS.<br>
<br>
We've tried using virtio and ide, with and without caching - the problem remains.<br>
<br>
The VM mounts its filesystem readonly and logs "journal I/O commit error", on the host system we get "end_request: I/O error, dev vda, sector" errors.<br>
<br>
Has some experienced similar problems?<br>
<br>
Cheers,<br>
Yves<br>
