<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just got very confused trying to add create an additional brick on my gluster node (I had created one yesterday and all was fine0<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I had already created a partition on my /dev/sdb called sdb1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But when I tried mkfs.xfs (I am using xfs as that was in the example I was following – if LVM or something else would be better I am open to suggestions!)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It said /dev/sdb1 no such file or directory – which confused me as this worked yesterday.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I deleted the partition recreated it and tried and then it said that the device was busy.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It appears that multipathd is the culprit… but what I am struggling with is why it worked yesterday?? I may have created the partition before I pushed the gluster install to it from the ovirt-engine? And does that install multi<span style="color:#1F497D">pathd
and it is now grabbing my devices? It is the only thing I can think of.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">And if that is the case – I guess I have to blacklist these devices in multipath.conf while I create the partitions? And reboot and then remove the blacklist and reboot – seems a bit clunky, is there a better
way to add partitions and bricks?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Or I am just in a vortex wormhole of misunderstanding and grasping at stars to try and pull myself out ?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thankyou for any advice – especially as this may not be so ovirt or a question, but it’s what I am working on.<o:p></o:p></span></p>
