<br>
I went through your logs of node 1 and by looking glusterd logs its clearly indicate that your 2nd node (10.32.1.144) have disconnected from the cluster, because of that remove-brick operation failed. I think you need to check your network interface.<br>
<br>
But surprising things is that i did not see duplicate peer entry in #gluster peer status command output.<br>
<br>
May be i will get some more information from your (10.32.1.144) 2nd node logs. Could you also attach your 2nd node logs.<br>
<br>
after restarting glusterd, are you seeing duplicate peer entry in #gluster peer status command output ?<br>
<br>
will wait for 2nd node logs for further analyzing duplicate peer entry problem.<br>

Hi Gaurav,<br>
<br>
Here, You can find the attached logs for the boards in case of remove-brick<br>
failure.<br>
In these logs we do not have the cmd_history and<br>
etc-glusterfs-glusterd.vol.log for the second board.<br>
<br>
May be for that we need to some more time.<br>
<br>
<br>
