&gt; Thank you so much for help :)<br>
&gt;<br>
&gt;<br>
&gt; I find these commands on the Web:<br>
&gt;<br>
&gt;<br>
&gt; First make sure it&#39;s unmounted:<br>
&gt;<br>
&gt; Code:<br>
&gt;<br>
&gt; sudo umount /sys/fs/pstore<br>
<br>
</span>Absolutely necessary.<br>
<span class=""><br>
&gt; Then edit /etc/fstab and remove the mountpoint from there.<br>
<br>
</span>Optional, but useful.<br>
<span class=""><br>
&gt; Finally delete the mountpoint from your filesystem:<br>
&gt;<br>
&gt; Code:<br>
&gt;<br>
&gt; sudo rmdir /sys/fs/pstore<br>
<br>
</span>Not sure this would work with virtual sysfs fs :)<br>
<br>
Thanks,<br>
