Can't figure how to make NFS work under OpenVZ
I've always used KVM or dedicated. Making a NFS server up and running was a piece of cake. Now I'm using a OpenVZ VPS and I'm having different issues.
From the OpenVZ wiki:
You will need the following software:
vzctl version 3.0.13 or higher (do vzctl --version)
kernel version 2.6.18-028test006 or higher (2.6.18-028stab* will do), or any recent RHEL5-based or 2.6.20-based kernel.
My requirements are met.
I already asked the VPS provider to load the NFS module, and she kindly did it. However, I get a time-out from my laptop (the client):
$ sudo mount IPADDRESS_OF_VPS:/home/issam/ /mnt/VPS
mount.nfs: Connection timed out
IPTABLES is not the issue:
issam@VPS:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Everything is allowed.
Did anyone successfully mounted an NFS server from an OpenVZ VPS?
Thanks!

Be sure to contact your provider and request that they enable NFS for your container. Once it has been enabled, follow the directions at the following page to setup NFS.
https://openvz.org/NFS
duh, did you even read his post? It was enabled already.
Thanks for the answer!
As I wrote, the provider already loaded it. But I still get the time-out. I also double checked the export list but it has no mistakes.
What does your NFS export look like?
Are you trying to access it over SSH portfowarding or a VPN?
@Bochi This is how my NFS export look like:
My laptop is behind a VPN. But I don't think it matters, I also mount NFS from the others VPS (behind a VPN) without any issue.
She might have missed a module.
Been there...
I asked her to double check. I hope it's not the case she forgot twice.
Firstly no offence take, but im a guy.. don't worry your not the first person to get confused.
Feel free to confirm back on the ticket and I will gladly have a look over your config and make sure their is nothing I can see you may have missed.
Ok, export looks good - nothing special.
So we are searching an error on your client side as the same share works correctly on the other machines?
/EDIT/
Maybe a stupid question, so forgive me, but:
You exports says you do it for your IP_HOME, but you just told us that you are using a VPN which would provide the VPNs IP to your NFS server?
Sorry for the confusion Ashley!
I wrote here simply because I didn't want to abuse of the support system for issues other than technical failures
Ok, the last time my provider told me he enabled the daemon but forgot the service. (It was a beta)
Here are the commands he used:
Also, try NFS 3, I've been told OpenVZ didn't support NFS 4
All other shares work perfectly on my laptop. I tried to mount the OpenVZ share on my laptop as well as in other machines (KVM VPS) but I always get a timeout.
Both where enabled at the same time, however as pointed out to Issam sometimes a reboot of the VM is required. @Issam2204 was this completed?
Yes..multiple times
Problem solved! The issue was that it needed a reboot from the provider' side. Now everything works perfectly!
I must say that ZXPlay has a top notch support! Tickets are replied within 15 minutes in the weekend! Unbelievable! Ashley followed my issues for different time with extreme professionalism and kindness.
Thanks everyone, and thank you Ashley!
Reboot of the node with hundreds of customers on it? Lovely.
The real solution is to just cancel all OpenVZ and don't even bother with it in the first place.
Ok, wait a minute. Let's not jump to conclusions and don't take my "explanations" as absolute. I don't specifically know what magic he did, but he did it. From my brief experience, ZXPlay showed to be an excellent VPS provider.
A reboot of the customers container from the command line.
Obviously not a full reboot of the node, which was never mentioned in the first place.
Edit:
However, yes I agree OpenVZ can be a pain, currently we only use it on the LET Storage offer, however a plan is in place to upgrade to KVM in the near future if the client wishes, to match the rest of our offerings.
The reboot could most likely have been done by the client from SolusVM (if thats the control panel used).
This is not the only thing that is solved by clicking that reboot button rather then issuing a reboot from inside the vm.
