WAN geo-replication support

[deajan]

First of all, sorry if this isn't the "good place" to post this. I've tried to register with slack first, but I don't have a "@leil.io" mail as requested for registering.

I'm currently investigating multiple technologies to achieve HA Linux KVM clusters, solutions considered being Storwind vSan, DRBD/OCFS2, MooseFS/LizardFS and Ceph.
One of my customers needs to have geo-replication for disaster recovery. So far, Linbit provides DRBD Proxy, and LizardFS claims to have geo-replication support on their website.

While comparing solutions, I've found SaunaFS. I've tried to read through the SaunaFS docs, but didn't find any geo replication documentation.
Can SaunaFS be used for geo-replication (WAN links with roughly 10ms latency, ie use async writes and cache whenever link is down) ?
And, since it seems to be a fairly new project, Is SaunaFS "production ready" ?
And last, I've seen the RPM build script dir, is RHEL ecosystem support a goal for SaunaFS ?

Thank you for any insight.

Hi @deajan, thanks for reaching out. Slack link should work for everyone externally.

As for your initial question, it is not a part of the main code and is not supported as a native feature but this is what supported with certain constraints. If you'd like to talk it further, let's proceed in email (ar@leil.io).

Thank you.
