<div dir="ltr">Hi There,
<div><br>
</div>
<div>I'm currently testing Gluster for possible production use.
I haven't been able to find the answer to this question in the
forum arch or in the public docs. It's possible that I don't
know which keywords to search for.</div>
<div><br>
</div>
<div>Here's the question (more details below): let's say that
one of my bricks "fails" -- <i>not</i> a whole node failure
but a single brick failure within the node. How do I replace a
single brick on a node and force a sync from one of the
replicas?</div>
<div><br>
</div>
<div>I have two nodes with 5 bricks each:</div>
<div>
<div>gluster> volume info test-a</div>
<div><br>
</div>
<div>Volume Name: test-a</div>
<div>Type: Distributed-Replicate</div>
<div>Volume ID: e8957773-dd36-44ae-b80a-01e22c78a8b4</div>
<div>Status: Started</div>
<div>Number of Bricks: 5 x 2 = 10</div>
<div>Transport-type: tcp</div>
<div>Bricks:</div>
<div>Brick1: 10.250.4.63:/localmnt/g1lv2</div>
<div>Brick2: 10.250.4.65:/localmnt/g2lv2</div>
<div>Brick3: 10.250.4.63:/localmnt/g1lv3</div>
<div>Brick4: 10.250.4.65:/localmnt/g2lv3</div>
<div>Brick5: 10.250.4.63:/localmnt/g1lv4</div>
<div>Brick6: 10.250.4.65:/localmnt/g2lv4</div>
<div>Brick7: 10.250.4.63:/localmnt/g1lv5</div>
<div>Brick8: 10.250.4.65:/localmnt/g2lv5</div>
<div>Brick9: 10.250.4.63:/localmnt/g1lv1</div>
<div>Brick10: 10.250.4.65:/localmnt/g2lv1</div>
</div>
<div><br>
</div>
<div>I formatted 10.250.4.65:/localmnt/g2lv5 (to simulate a
"failure"). What is the next step? I have tried various
combinations of removing and re-adding the brick, replacing
the brick, etc. I read in a previous message to this list that
replace-brick was for planned changes which makes sense, so
that's probably not my next step.</div>
</div>

You must first check if the 'formatted' brick
10.250.4.65:/localmnt/g2lv5 is online using the `gluster volume
status` command. If not start the volume using `gluster volume start
<VOLNAME>force`. You can then use the gluster volume heal
command which would copy the data from the other replica brick into
your formatted brick.<br>
Hope this helps.<br>
