Anybody has recommendation schema of infrastrucure for HA hosting service?
Hello–
InterWorx does not really support HA at all, in general–in our clustered environments, the cluster manager is the single point of failure, as that is where all of the data actually lies.

OK, its bad. Any other solution when cluster manager will fail?
I can backup this server but it will lost 1 day data. I had question if is possible make system DB set as master and another as slave, but its not possible as I understod. So how to use
Hello–
I’m sorry, I’m not entirely certain what you’re asking, especially because it looks like your last statement was cut off–it just says “how to use”. Did you mean to cut off there?
You can add a remote db if you would like. However, that would not create an HA environment.
The cluster manager holds all of the site data, email, internal iworxdb info, account info, etc. In a cluster, the nodes are just NFS shares.

Sorry, I meant if is possible configure system DB as master and another as slave. When replication will start it will start with slave DB.
Hello–
You can add remote mysql servers and replicate information for the system MySQL instance if you want.
That will not stop the main InterWorx server from being a single point of failure. If the main InterWorx server goes down, all of the sites and email will still go down because that is where the site data, apache, email services, etc all live.
All that will do is just have the remote MySQL server up and running with the existing data. But it won’t have anywhere to serve that data to, because there won’t be any services running to serve it.

Yes sure, I know, my plan is to dedicate everything outside and leave managed server clen only for managing with very fast recovery from backup.
Soo, my question changed. Is it possible move all these data outside of server? Are all data storage locations reconfigurable?
Hello–
No, you cannot move site or email data outside of the server that the site and email is hosted on.
Thanks,
-Jenna
Why not? Its only storage thing and nothing special and reason to be on same server.
Hello–
By site data, I mean what is located in /home/user. The DocumentRoot for the domain.
Apache serves the contents of the website based on the DocumentRoot listed in the vhost.
If the DocumentRoot–where the data for the site is located–the information located under /home/user–does not exist on the server, there is nothing for Apache to serve and the site will be broken.
If you are using InterWorx, ALL site data must be located under /home/user on the server that InterWorx is installed on. There is no way to change that. You cannot move site data to a remote server while using InterWorx. InterWorx won’t know about it if it is on a different server. Neither will Apache.

Do you want to say, that when /home/… will be mapped to raid storage it will not work? It will look like /home/… too or not?
Hello–
/home cannot reside on a different server. InterWorx will not work if /home does not reside on the same server. /home can be its down partition if you’d like, but it cannot be, for instance, and NFS share the resides somewhere not on the server.
You are free to try a custom set up with /home on a remote server, if you would like, to test for yourself it if will work, but that is 100% an unsupported environment and we will not be able to assist if anything breaks within that set up in any way, shape, or form.
And even if you were to set it up that way and it worked, that wouldn’t solve the InterWorx server being the point of failure because the Apache service is on the main server, and THAT Would be down if the main server went down. There wouldn’t be a service to serve your websites.
Thanks,
