<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">Hi All,</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">&nbsp;</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I am using DRBD( version: 8.0.5). I 
want to use LVM over DRBD. I am facing some problem after DRBD configuration. 
</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">&nbsp;</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">For configuration I have used 
physical disks i.e. /dev/sdb (on local) and /dev/sdc (on remote). &nbsp;The 
configuration was successful. But I want to create VG and LV on this DRBD device 
(/dev/drbd0). I have made changes in lvm.conf. I have changed the LVM filter 
(<b><i><span style="font-weight: bold; font-style: italic;">filter = [ &quot;a|sd.*|&quot;, 
&quot;a/drbd.*/&quot;, &quot;r|.*|&quot;]</span></i></b>) to accept the DRBD devices. Then I 
performed pvcreate and vgcreate.</span></font></p>
