Thank you sac,
That worked like a champ. I also ran the same command on brick 2 of the pair.
Hopefully I will be able to help out in the future. Thank you again.

Gluster Gurus,
I am having an issue removing a gluster replica pair. I have tried numerous different iterations of the command and get back ‘Incorrect brick tx4-gluster1-10:/brick10 for volume gv0’
Here is the output of “gluster volume info”:

I would like to remove gluster1-10 from the gluster cluster.
Here is my command:
gluster volume remove-brick gv0 replica 2 tx4-gluster1-10:/brick1 tx4-gluster1-10:/brick2 force
You are getting the command wrong here. You can remove the replica pairs, in your case the pairs are:
Brick9: tx4-gluster1-9:/brick1/brick
Brick10: tx4-gluster1-10:/brick1/brick
And your command would be:
gluster volume remove-brick gv0 replica 2 tx4-gluster1-9:/brick1/brick tx4-gluster1-10:/brick1/brick
And if I understand correctly you want to remove the host gluster1-10 from the cluster which is part of two replica pairs. So you will end up removing two replica pairs if you want to remove gluster1-10 from the cluster.
-sac
Here is the result:
volume remove-brick commit force: failed: Incorrect brick tx4-gluster1-10:/brick1 for volume gv0
I have tried a number of iterations here, using different names and trying tx4-gluster1-10 and 1-9 bricks. Nothing has worked so far.
This is a test setup so we don’t care about data, we just need to learn.
We will probably not put the node back in after removal.
Any help would be greatly appreciated.
Thank you in advance.
Best regards,
Rob Moss
