[Gluster-users] Rebalance failed on Distributed Disperse volume based on 3.12.14 version
Dear Ashish, thank you for you answer. I could provide you the entire log file related to glusterd, glusterfsd and rebalance. Please, could you indicate which one you need first? Yes, we added the last 36 bricks after creating vol. Is there a procedure to correct this error? Is it still possible to do it?

[Gluster-users] Rebalance failed on Distributed Disperse volume based on 3.12.14 version
Hi Mauro,
rebalance and brick logs should be the first thing we should go through.
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.

Dear Ashish,
thank you for you answer.
I could provide you the entire log file related to glusterd, glusterfsd and
rebalance.
Please, could you indicate which one you need first?
Yes, we added the last 36 bricks after creating vol. Is there a procedure to
correct this error? Is it still possible to do it?
Many thanks,
Mauro

I think we don't have enough logs to debug this so I would suggest you to
provide more logs/info.
I have also observed that the configuration and setup of your volume is not very
efficient.
For example:
Brick37: s04-stg:/gluster/mnt1/brick
Brick38: s04-stg:/gluster/mnt2/brick
Brick39: s04-stg:/gluster/mnt3/brick
Brick40: s04-stg:/gluster/mnt4/brick
Brick41: s04-stg:/gluster/mnt5/brick
Brick42: s04-stg:/gluster/mnt6/brick
Brick43: s04-stg:/gluster/mnt7/brick
Brick44: s04-stg:/gluster/mnt8/brick
Brick45: s04-stg:/gluster/mnt9/brick
Brick46: s04-stg:/gluster/mnt10/brick
Brick47: s04-stg:/gluster/mnt11/brick
Brick48: s04-stg:/gluster/mnt12/brick
These 12 bricks are on same node and the sub volume made up of these bricks will
be of same subvolume, which is not good. Same is true for the bricks hosted on
s05-stg and s06-stg
I think you have added these bricks after creating vol. The probability of
disruption in connection of these bricks will be higher in this case.

Dear All, Dear Nithya,
after upgrading from 3.10.5 version to 3.12.14, I tried to start a rebalance
process to distribute data across the bricks, but something goes wrong.
Rebalance failed on different nodes and the time value needed to complete the
procedure seems to be very high.

It seems that there are some network or timeout problems, but the network

Do you think that, in my volume configuration, I have to modify some volume
options related to thread and/or network parameters?
Could you, please, help me to understand the cause of the problems above?

If it can help, I paste here the output of ?free -m? command executed on all the
cluster nodes:
The result is almost the same on every nodes. In your opinion, the available RAM
is enough to support data movement?
[root at s06 ~]# free -m
total used free shared buff/cache available
Mem: 64309 10409 464 15 53434 52998
Swap: 65535 103 65432
Thank you in advance.
Sorry for my long message, but I?m trying to notify you all available
information.
Regards,
Mauro
