Hello,

I'd like to know if it's possible to have a dedicated server for the master and then other datacenters utilize dedicated servers as the slaves that we can put 10 VPS on each slave server? This is probably how it works but I'd still like confirmation.

What happens if the master server goes down for like 8 hours? do the slave servers in other datacenters also go down? What happens technically?  If the master reboots and comes back do the slaves in other DCs re-negoitate? Also what would happen (technically) if the master server never came back? would the VPS on other slave machines still function? For how long? and what happens if?

Thanks

Hi,

If the Master server/panel is down then you won't be able to manage your slaves from master panel for that period of time.
That will not affect any vps functioning.
But no action from panel will be allowed from slave panel.


If your master server is down permanently then you can try this guide to move to a new master :

Thanks for the information.  Makes sense.

Does your team offer a service where your customers advise the setup required and you can be commissioned to help us with that setup for a fee?

The pain points we will be dealing with is how to properly setup a scalable service where all the VPSes we add to the servers can have their HDD's increased as required.  The idea is to set all VPS on 10GB and plug in a few servers for space to be used when a customer demands more space.

The other things we will require is what steps to perform to restore a VPS that is broken or won't come back up .. and the ability for our team to restore from a working snapshot.  If documentation is available for this, great... but having a point of contact with your team regarding these issues would be preferable (and not on the public forum) so if you can point me in a direction for this type of contact or communication with your services, would be great to know before we get this going.

Basically we're looking for some guidance (in the beginning) and a point of contact on those "my VPS is down" moments that we may face but need to have a "plan b" to serve the customer in the most professional way possible.

Thanks in advance.

Hi,


You can view this guide to setup backup plans that can be used to create vps backups and restore them when required.

https://www.virtualizor.com/docs/admin/backup-plans

For disaster recovery , you can have a look at this guide :

https://www.virtualizor.com/blog/docs/faq/disaster-recovery/

And are you going to use WHMCS/Blesta billing modules as well ?
Users can choose upgrade options from there and get their vps resources upgraded whenever required.

You can reach us on ticket and on chat as well.

Thanks again for your replies. 

Does your team offer a service that if this happens the disaster recovery service can be paid for? In the event we don't want to tackle this ourselves?  I understand your team is PRO software development which you've come a great way with this product.. hands down! but for the clients who are already established and want to have their hands held during a disaster event? If not, do you have any 3rd party providers that offer this service who know your product inside and out?

Thanks guys
