Virtualmin cannot create subserver document root

et100 · October 15, 2011, 7:09pm

Hi!
First of all, thank you for such great program!

With many hours of trial-and-error, I’ve managed to successfully created a virtual server.
Now, I wanted to create something like sub1.mydomain.com - so I decided to create a subserver under a virtual server.

Virtualmin does not show any error messages.
Everything is well, except the fact that even though Virtualmin reports

/home/mydomain/domains/sub1.mydomain.com/public_html

exists, it really does not.

In simple words, Virtualmin cannot create folders for subservers.

I’m wondering if it’s due to my server’s permission or wrong nameserver settings, or etc.

I’d appreciate any input. Thank you!

NOTE: Here’s my setup
OpenVZ VPS
Centos 6 64-bit
Apache

Howdy,

Well, we’ve run into a lot of strange problems on OpenVZ-based systems due to how it handles memory management… it’s possible that’s what you’re running into.

Can you paste in the contents of your /proc/user_beancounters file?

Also, what does “free -m” show on your server?

Lastly, does the domain “/home/mydomain/” exist?

Thank you for the quick reply!

While I was waiting, I rebooted my server and tried again. This time, Virtualmin successfully created “/home/mydomain” folder with all the correct path.

Now the problem is that the subdomain isn’t connecting at all. No error messages, nothing.
Whole new set of problem.

Should I still copy/past those infos that you requested? Or is this a whole different problem now?

While the issues you’re seeing seem unrelated – it’s possible they share the same underlying cause… and your /proc/user_beancounters and free -m output may show if that’s the case.

Thanks!

Thank you. I really appreciate it! :)

Hrm, my hunch is that you’re hitting resource limits of some kind… but I’m not sure which ones exactly, and they aren’t showing up as I’d have hoped in your user_beancounters file.

What output do you receive if you run the command “dmesg | tail -30”?

Also, when you say the subdomain isn’t connecting – what do you mean exactly… can you describe what you’re trying, and what happens when you try?

Sorry for the late update.
I just decided to go with Centos 6.0 32-bit. Killed all the unused services, moved my DNS service to other servers; now everything works correctly.

I also noticed that the 32bit OS + VirtualMin/Webmin combo uses less memory for my setup.

Thank you for such great software!
