<div dir="ltr">Ravi,<div>We had earlier discussed a solution for this (sometime last year) by making volgen remember xlator names and not reassign them. Copying KP with who I had discussed this to quite a level of detail. Have you guys spoken about this? IIRC the solution KP and I discussed was more generic and could also support retaining user made changes/customizations to the volfiles.</div>

As you might perhaps be aware, AFR translator currently uses the client translator names as the name of it's changelog extended attributes.<br>
<br>
i)This can be a problem when a remove-brick operation is performed when there are pending heals happening because remove-brick causes a graph change wherein the client translator names become different.<br>
<br>
ii) Also, for gluster snapshot volumes to work correctly, there needs to be a persistent mapping of AFR changelog attributes to the bricks.<br>
<br>
After some internal discussions, we have come up with a new naming mechanism that ensures backward compatibility. Details on the aforementioned problems and the proposed solution are detailed in a feature page [1] for GlusterFS 3.6.<br>
Please feel free to go through it and give your comments/ critiques.<br>
<br>
Thanks and regards,<br>
