[Gluster-users] Failures during rebalance on gluster distributed disperse volume
Dear All,
I recently added 3 servers (each one with 12 bricks) to an existing Gluster
Distributed Disperse Volume.
Volume extension has been completed without error and I already executed the
rebalance procedure with fix-layout option with no problem.
I just launched the rebalance procedure without fix-layout option, but, as you
can see in the output below, I noticed that some failures have been detected.
[root at s01 glusterfs]# gluster v rebalance tier2 status

In the volume rebalance log file, I detected a lot of error messages similar to
the following ones:

Could you please help me to understand what is happening and how to solve it?
Our Gluster implementation is based on Gluster v.3.10.5
Thank you in advance,
Mauro

[Gluster-users] Failures during rebalance on gluster distributed disperse volume
This looks like an issue because rebalance switched to using fallocate which EC did not have implemented at that point. @Pranith, @Ashish, which version of gluster had support for fallocate in EC?
