[Users] Can I use IP address for FQDN?

Sat Jan 11 01:19:59 UTC 2014

By chance do you have a firewall enabled on your nfs host. If you do have a firewall enabled, do you have the following ports open?

TCP/UDP 111

TCP/UDP 2049

And the ports defined in /etc/sysconfig/nfs

Can you upload the portion of your vdsm.log that show the failure?

Sorry hit the key too fast. Here it is again:

/var/lib/exports/iso               0.0.0.0/0.0.0.0

And cat /etc/exports:

/var/lib/exports/iso       0.0.0.0/0.0.0.0(rw)

Run showmount –e <name of your nfs host> to see if the mounts are advertised properly

So your command should look something like

#showmount –e host.example.com <http://host.example.com/>

I just added a line to both /etc/hosts file. This time when I tried to attach the NFS ISO domain, it showed up as "locked" but eventually disappeared again from the web portal. 

I looked at the vdsm.log and found it might be that the mount timed out for some reason. But not quite sure why. 

Anyone has any idea what exactly I should be searching for in vdsm.log?

Is this the /etc/hosts file on the engine machine or the node machine?

you can set a static FQDN if you dont have a dns server in /etc/hosts, however if you do this, set the same FQDNs on all hosts for each hosts

192.168.0.1     node1.test.com <http://node1.test.com/>    node1

192.168.0.2     node2.test.com <http://node2.test.com/>    node2

192.168.0.3     node3.test.com <http://node3.test.com/>    node3

use that fqdn for your engine/node during the engine install.

Hi,

I have set up a default FQDN ( for the engine machine) at engine installation. But this is not resolvable by the node when it tries to mount the NFS ISO share from the engine. Is there anyway that I can update this name on the engine to using a IP address?
