Your procedure and description is very detailed. I think to follow the first approach after setting network.ping-timeout option to 0 (If I’m not wrong “0" means “infinite”...I noticed that this value reduced rebalance errors). After the fix I will set network.ping-timeout option to default value. Could I contact you again if I need some kind of suggestion? Thank you very much again.

That means, there are 6 ec subvolumes and we have to deal with one sub volume at a time. I have named it V1 to V6. Problem: Take the case of V1. The best configuration/setup would be to have all the 6 bricks of V1 on 6 different nodes. However, in your case you have added 3 new nodes. So, at least we should have 2 bricks on 3 different newly added nodes. This way, in 4+2 EC configuration, even if one node goes down you will have 4 other bricks of that volume and the data on that volume would be accessible. In current setup if s04-stg goes down, you will loose all the data on V1 and V2 as all the bricks will be down. We want to avoid and correct it. Now, we can have two approach to correct/modify this setup. Approach 1 We have to remove all the newly added bricks in a set of 6 bricks. This will trigger re- balance and move whole data to other sub volumes. Repeat the above step and then once all the bricks are removed, add those bricks again in a set of 6 bricks, this time have 2 bricks from each of the 3 newly added Nodes. While this is a valid and working approach, I personally think that this will take long time and also require lot of movement of data. Approach 2 In this approach we can use the heal process. We have to deal with all the volumes (V1 to V6) one by one. Following are the steps for V1- Step 1 - Use replace-brick command to move following bricks on s05-stg node one by one (heal should be completed after every replace brick command) Brick39: s04-stg:/gluster/mnt3/brick to s05-stg/<brick which is free> Brick40: s04-stg:/gluster/mnt4/brick to s05-stg/<other brick which is free> Command : gluster v replace-brick <volname> s04-stg:/gluster/mnt3/brick s05-stg:/<brick which is free> commit force Try to give names to the bricks so that you can identify which 6 bricks belongs to same ec subvolume Use replace-brick command to move following bricks on s06-stg node one by one Brick41: s04-stg:/gluster/mnt5/brick to s06-stg/<brick which is free> Brick42: s04-stg:/gluster/mnt6/brick to s06-stg/<other brick which is free> Step 2 - After, every replace-brick command, you have to wait for heal to be completed. check "gluster v heal <volname> info " if it shows any entry you have to wait for it to be completed. After successful step 1 and step 2, setup for sub volume V1 will be fixed. The same steps you have to perform for other volumes. Only thing is that the nodes would be different on which you have to move the bricks.

There is a procedure to correct the configuration/setup but the situation you are in is difficult to follow that procedure. You should have added the bricks hosted on s04-stg , s05-stg and s06-stg the same way you had the previous configuration. That means 2 bricks on each node for one subvolume. The procedure will require a lot of replace bricks which will again need healing and all. In addition to that we have to wait for re-balance to complete. I would suggest that if whole data has not been rebalanced and if you can stop the rebalance and remove these newly added bricks properly then you should remove these newly added bricks. After that, add these bricks so that you have 2 bricks of each volume on 3 newly added nodes. Yes, it is like undoing whole effort but it is better to do it now then facing issues in future when it will be almost impossible to correct these things if you have lots of data. --- Ashish ----- Original Message ----- From: "Mauro Tridici" < [email protected] > To: "Ashish Pandey" < [email protected] > Cc: "gluster-users" < [email protected] > Sent: Wednesday, September 26, 2018 5:55:02 PM Subject: Re: [Gluster-users] Rebalance failed on Distributed Disperse volume based on 3.12.14 version Dear Ashish, thank you for you answer.

Same is true for the bricks hosted on s05-stg and s06-stg I think you have added these bricks after creating vol.
