[Gluster-users] self healing with sharding

Let's assume a 3 node cluster with replica 3 and a huge file (1GB)
with shard size of 100MB

Gluster automatically create 10 chunks for the file.

In a 3 node cluster with replica 3, all chunks are on every server.

A node dies.

When the node comes back online, self healing is triggered.
In this case, the whole file would be healed, as all shards must be
replicated, right ?
Any advantage with this over a standard configuration without shard?
