[Gluster-users] Gluster 3.8.10 rebalance VMs corruption

[Gandalf Corvotempesta]

Krutika, it wasn't an attack directly to you.
It wasn't an attack at all.

Gluster is a "SCALE-OUT" software defined storage, the folllowing is
wrote in the middle of the homepage:
"GlusterFS is a scalable network filesystem"

So, scaling a cluster is one of the primary goal of gluster.

A critical bug that prevent gluster from being scaled without loosing
data was discovered 1 year ago, and took 1 year to be fixed.

If gluster isn't able to ensure data consistency when doing it's
primary role, scaling up a storage, i'm sorry but it can't be
considered "enterprise" ready or production ready.
Maybe SOHO for small offices or home users, but in enterprises, data
consistency and reliability is the most important thing and gluster
isn't able to guarantee this even
doing a very basic routine procedure that should be considered as the
basis of the whole gluster project (as wrote on gluster's homepage)
