[Gluster-devel] [Questions] why shard feature doesn't support quota

[Krutika Dhananjay]

This is based on my high-level understanding of quota in gluster -
supporting quota on sharded volumes will require us to make quota xlator
account for shards residing under the hidden ".shard" directory per file
and adding this to the quota-xattr representing aggregated consumed size on
the parent directory of the original file.

This isn't hard to do. But at the moment we support sharding only for VM
image store use case.
There are plans to make shard useful for more generic use cases in the near
term. When we get there, we will support quota too on sharded files.
