[Gluster-users] Issue when upgrading from 3.6 to 3.7

Manikandan,

We just overwrote the setup with a fresh install and there I see the
quota-version in the volume info file. For the upgraded setup, I only have
the /var/lib/glusterd, which I'm attaching. Once we recreate this, I'll
send you the rest of the info.

However, is there an issue if the quota-version is not being in the info
file? Will it cause the quota functionality to malfunction?
