VMKernel Network Problem

[m4st0r]

Hey,

Well I'm trying to add a NFS Share to one of my ESX 3.5 Server. I have 2 NIC, one for the service console and the other for the virtual network.

Is there any possibility to add the VMKernel Network with the same IP Addresse of the Service Console?

Any suggestions? I have only two NIC in my HP Proliant server.

Thanks.

You cant have same IP add. for service console and VMKernel. Suggesting you that keep the Service Console and Virtual Machine on the first NIC and use the VMkernel on the 2nd NIC.

Hello,

Jou can add a second SC and an VMkernel for storage both with its own IP adress on one of the vSwitches, add the IP adresses to the NFS server to access it.

check if you can vmkping the NFS server from the service console and connect to the NFS server.

it's far from ideal, only two nics and no redundancy in anyway. I would suggest combining it all to one vSwitch with the two nics so you atleast have some redundancy. Anyway you can add the VMkernel to the SC vSwitch and just assign a new IP. The same IP will not work. (Conflicts...)

Thanks for the answer, I will buy another two NIC for this server this week.

For the moment I will use the VMKernel and the SC on the same network.

I've tried to connect the NFS Server to one of the ESX3.5 Server and it says : Unable to connect to NFS Server

Sounds like a network problem? I can ping the VMKernel & NFS Server from the ESX Server.

NFS Server works finde, just tried mount localhost and it works...

Any suggestions? Thanks

If there is any security settings on the NFS Server side, allow the VMKernel IP address to access the mount.

Also, try the vmkping command to ping the NFS server

1. Allow access for the SC and de VMkernel IP adress on the NFS server.

2. vmkping the ip of de NFS server on the ESX server

3. from the SC -> /usr/sbin/esxcfg-nas -a -o <IP NFS SERVER> -s <SHARENAME> <NAME>

vmkping is working from the ESX to the NFS Server.

If I try to mount the device a messeage appears like "Unable to connect to NAS Server"

/etc/exports looks like this:

/test 10.0.0.2(rw,no_root_squash)

/test 10.0.0.5(rw,no_root_squash)

and hosts.allow like this:

ALL:10.0.0.2

ALL:10.0.0.5

10.0.0.2 is the ESX server and 10.0.0.5 the VMkernel IP adresse....

& dont forget to enable "nfs client" on ESX security profile too.

Yes I'm new to vmware infrastructure 3..but I can't find any doc about sharing NFS on vmware...

NFS port is already open on the ESX Server but it can not connect to the share? :S

[athlon_crazy]

Have you checkversion of your NFS server? Like ESX, it's only can mount NFS v3 running over tcp.

If I run nfsstat on the Fedora NFS Server it tells my that I'm running "Server nfs v3"..

Maybe I need to give also access to the VCenter on the NFS Server in hosts.allow?

[m4st0r]

Well I found the problem, NFS works fine now ..

The problem was the IP Filter which was enabled on the NFS Server (Fedora Linux).

Anyway, thanks for help guys.
