I am landing here again following a spell on the list when I worked at XMA in the UK. Hello again. I have a use case of having a remote office, which should be able to have a common storage area with a main office. At the last company I worked with, we used GPFS with AFM to achieve this (not really relevant to this list). I at first though Geo Replication would be ideal for this use case, however further reading says that it is suitable for making a slave only copy for disaster recovery. Ie. there is no 'two way' syncing of files. To make it a bit clearer, the concept is that the remote site might be in the USA, and the home site in Europe. Scientists at the remote site copy files for analysis to a local storage server. At the home site there should be a replica of the analysis files. At the home site there are HPC resources to run simulations or process the data somehow. Results files are written to a storage server and then should be replicated back to the remote site. Would anyone be able to comment on the New Style Geo Replication which has come along in Gluster version 4? What is the status please, and is it a suitable method for enabling a share at a remote office which syncs either way? thankyou John Hearns -------------- next part -------------- An HTML attachment was scrubbed...

[Gluster-users] New Style Replication in Version 4
Hi John Hearns, Thanks for considering gluster. The feature you are requesting is Active-Active and is not available with geo-replication in 4.0. So, the use case can't be achieved using single gluster volume. But your use case can be achieved if we keep two volumes one for analysis file and other for result files if the there is distinction between analysis files and result files. Home Site/Europe Remote Site/USA Analysis Files Volume (Geo-rep Slave) <-------- Analysis Files Volume (Geo-rep Master) Results Files Volume (Geo-rep Master) ---------> Results Files Volume (Geo-rep Slave) Thanks, Kotresh HR On Mon, Apr 30, 2018 at 4:56 PM, John Hearns <hearnsj at googlemail.com> wrote:> I am landing here again following a spell on the list when I worked at XMA > in the UK.
