[Gluster-users] Issue in Adding/Removing the gluster node

Fri Feb 19 11:33:00 UTC 2016

Hi Abhishek, 

How are you connecting two board, and how are you removing it manually that need to know because if you are removing your 2nd board from the cluster (abrupt shutdown) then you can't perform remove brick operation in 2nd node from first node and its happening successfully in your case. could you ensure your network connection once again while removing and bringing back your node again. 

Thanks, 
Gaurav

Hi Gaurav, 

Thanks for reply 

1. Here, I removed the board manually here but this time it works fine 

[2016-02-18 10:03:40.601472] : volume remove-brick c_glusterfs replica 1 10.32.1.144:/opt/lvmdir/c2/brick force : SUCCESS 
[2016-02-18 10:03:40.885973] : peer detach 10.32.1.144 : SUCCESS 

Yes this time board is reachable but how? don't know because board is detached. 

2. Here, I attached the board this time its works fine in add-bricks 

2016-02-18 10:03:42.065038] : peer probe 10.32.1.144 : SUCCESS 
[2016-02-18 10:03:44.563546] : volume add-brick c_glusterfs replica 2 10.32.1.144:/opt/lvmdir/c2/brick force : SUCCESS 

3.Here, again I removed the board this time failed occur 

[2016-02-18 10:37:02.816089] : volume remove-brick c_glusterfs replica 1 10.32.1.144:/opt/lvmdir/c2/brick force : FAILED : Incorrect brick 10.32.1.144:/opt 
/lvmdir/c2/brick for volume c_glusterfs 

but here board is not reachable. 

why this inconsistency is there while doing the same step multiple time. 

Hope you are getting my point. 

Regards, 
Abhishek

Abhishek, 

when sometime its working fine means 2nd board network connection is reachable to first node. you can conform this by executing same #gluster peer status command. 

Thanks, 
Gaurav

Hi Gaurav, 

Yes, you are right actually I am force fully detaching the node from the 
slave and when we removed the board it disconnected from the another board. 

but my question is I am doing this process multiple time some time it works 
fine but some time it gave these errors. 

you can see the following logs from cmd_history.log file
