NFS support

[thesti]

I know there was a thread I read about this but I'm wondering what the status is.

I think many people wouldn't mind being able to host redundant DA servers.

The scenario would be two load balancers of any sort that would direct traffic to other Virtual DA servers which all have the same NFS mounted.

I know a hurdle is #1 DA does not work without public IPs (can we change it?)

And #2 the whole licensing issue.

I think if people knew this was supported and if the application vault were added Cpanel and Plesk would be dead.

There is an applicatiion vault. Installatron and it's the best of them all.

It's unlikely that JBMC will change the licensing method for DA to not require public IP#s.

I'm not sure what you mean by "the whole licensing issue".

NFS has some issues with locking, and some more with security (the security issues would probably be eliminated if you could run the NFS server on local IP#s).

And there's still that single point of failure of NFS.

I know, I read a thread about the licensing issue regarding DA on non-public IPs.

I am fully aware the NFS server is a single point of failure though the purpose of this discussion is more so to find away to achieve the goal of clustering (albeit with a single point of failure) and using NFS (and NFS in this architecture I speak of would be using private IPs though again this is not about security either).

Thanks for your input. I hope some of us can come together and find a way to make this work. H-Sphere sounds like it would out of the box but the $4.50/account is kind of crazy.

I'd think then that DA would work fine in your scenario, though there might be a problem with locking pop mbox files.

Of course you'd have to buy a license for each server running DA, but I don't see that as an issue; certainly we expect to pay JBMC for their work, and they've chosen a per-server license model.

H-Sphere has chosen the per-user license model, and that's not terrible either; it's simply a matter of take your choice and live with it.

What I don't like about H-Sphere is qmail.

YMMV.

Thanks again Jeff for your reply. Just to make it clear though, you're saying the setup I mentioned would work?

I thought I read in a previous thread with you involved that you can't host Direct Admin on private IPs (the DA servers would be on private IPs in the same subnet with the NFS server).

Sitting at the front would be two non-DA servers which would act as load balancers (they would have public IPs and also internal IPs of the same subnet as the NFS and DA servers).

I don't mind paying per DA server for the licence of course (I was just under the impression that DA would not at all run with private IPs?)

Thanks again

p.s. the thread I'm talking about is

I guess I misunerstood you; your load balancing method would have to have public IP#s for the DA servers for this to work.

I was referring to private IP# space for the NFS server; that wouldn't be a problem.
