Hi Sahina:
Thanks for getting back to me. I took away 3 action items from the email:
Geo-replication session configuration options mockup -- we're working on
putting something together
Dashboard - what to show in the dashboard; we're working on putting
something together
Checkpoint history - what to show. Here's what I believe you should show:
* show what you would get from the "# gluster volume geo-replication
<source_volume> <destination_host>::<destination_volume> config
log-file | xargs grep checkpoint" command
* show the following columns (I'll assume you don't need a mockup as
this most likely would be shown in a table)
o checkpoint name, checkpoint creation date, amount of data
transferred (indicate if delta or cumulative size), status
Please feel free to forward to oVirt users.
Thanks,
Ju

This tab would be empty if there are no replication sessions.
But having a tab will all replication sessions would be useful and
could be used to start a new one.

No, no proposal yet.

We are trying to be consistent with the verbs..and have changed to
Volume -> New for creating a volume. So it should be "New Session" IMO

Yes, it can be the same dialog. The information regarding source
volume would be prefilled if it's coming from the geo-replication sub-tab.

Destination volume can be of a different volume type.

We were planning to have a UI similar to the volume options. Do let us
know, if there's a better way to do this.

Session details view will also show information on files/bytes
skipped, moved etc per brick node.
Regarding checkpoint, there's currently only a checkpoint status being
shown. There's some enhancements to be done in gluster geo-rep with
regards to checkpoints
What information would need to be shown in checkpoint history?

Yes, we have introduced a volume capacity column in the Volumes tab,
which will show these details.

We could change in the docs and UI...CLI, not so sure.

If you have suggestions on showing the configuration options and for
the dashboard, that would be welcome.
I could forward this to ovirt users for wider circulation.
