<p dir="ltr">Ideally a same node shouldn't have multiple UUIDs, which is unfortunately true in your setup. I do not see any straight forward case which can lead to this issue. What Gluster version are you using?</p>

<br>
we're seeing multiple entries for nodes in pool list & peer status, each associated with a unique UUID.<br>
Filesystem seems to be working, but we need to clean this up in anticipation of any future issues.<br>
<br>
The nodes with multiple UUIDs were previously disconnected, but they're good now.<br>
<br>
Does anyone know what's going on & how we can resolve this issue?<br>
<br>
thanks,<br>

I can do a generalized setup of gluster, but I'm not sure how to read this error and how to fix it. Can anyone provide some<br>
assistance?<br>
