[Gluster-users] URGENT: Update issues from 3.6.6 to 3.10.2 Accessing files via samba come up with permission denied

[Raghavendra Talur]

If possible please share the glusterfs-* log files from /var/log/samba.

This might be because of cluster.lookup-optimize. Adding Poornima and
Raghavendra Gowdappa to help with this.
