<div class="moz-cite-prefix">It would help if you say what kind of
volumes you have, as they all work a little differently.<br>
<br>
You should NOT destroy the old volumes.<br>
<br>
It should be quite possible to move the bricks to a new server and
get them running as part of THE SAME gluster system that you have
now.<br>
<br>
Until you tell us how many bricks, how many servers have what
bricks, exactly which servers you are replacing (you mention only
one server, but that is not a normal gluster configuration), we
can't give you a whole lot of help. The usual routine involves
working with one brick server at a time, while keeping the rest of
the array untouched. With some replicated arrays and some careful
work, you don't have to take the array offline at all. However,
replicated arrays get handled VERY differently from distributed,
so we can't help much until you tell us more.<br>

<div>hi, I did not see a reply to my problem. Let me ask it
in a different way...<br>
<br>
</div>
If I have bricks from a previous glusterfs volume and that
volume is now gone because of the old machine was replaced,
now I tried to create a new volume and add the old bricks to
the new volume with the "force" opinion to "volume create".
The old data files are still in the bricks but when I mount
the new volume the new volume shows it is empty.<br>
<br>
</div>
Is it possible for glusterfs to recognize the old data files on
the bricks in some way to essentially re-create the same view as
the old volume, via some kind of healing or meta data re-scan or
re-creation? The bricks are in good shape with no data
corruption and are in sync (same data were replicated). Thanks<br>

<div>Hi, I have a gluster volume with bricks spread over
several physical drives. I now want to upgrade my
server to a new system and plan to move the drives
from the old server to the new server, with a
different host name and IP address. Can I shut down
the gluster volume on the old server, move and install
the physical drives containing the bricks to the new
server, and then create a new gluster volume on the
new server, and add the bricks to the new volume in
the same way reflecting the previous organization of
the volume on the old server, and expect everything to
work (all files preserved and accessible via
glusterfs, with no data loss? <br>
<br>
</div>
The gluster volume on the old server would be retired
and I want to let the new server taking over the role of
serving the gluster volume.<br>
<br>
</div>
