Dear Darrell,
Dear ...,
Many thanks for the prompt reply. Here some of the additional
information requested (please feel free to ask for more if needed)

All disks use virtIO drivers (virtIO disks).
The file system on all nodes is XFS (not ZFS)
Other than the clients on the gluster nodes themselves there are clients
on ctdbs that mount the gluster volume and then expose it via smb to
Windows clients (user profiles included for roaming profiles).
ctdbs reach the glusters through the heartbeat network
We are considering to move the glusters to a network with existing DNS
capabilities in order to create a round-robin configuration by assigning
hosts by IP to a single hostname to use it then for the mounts
configuration of the ctdbs.
The reasoning/hope behind that we would minimize access time and sync
issues.
Thank you for the information about the "sharding" we will take this
into account and consider pros and cons in the current situation,
epsecially because turning back is not easy afterwards. Also our main
problem is mainly not with big files, but with a large quantity of small
files.
We could gladly make use of some of the options you suggested after we
assess the situation again. We welcome any further suggestion in the
meantime.
