Hi Sergio,
Dont worry about the questions, this a list for help.
I see that nobody:nogroup is the owner of the top folder, i think this is wrong, change with a chown -R to root:root for the top folder, be sure of all the files have root:root, and try again.

drwxrwxr-x 2 nobody nogroup 4096 abr 25 2012 ./
drwxrwxrwx 4 root root 4096 abr 25 2012 ../
-rw-rw---- 1 root root 0 abr 25 2012 console.log
-rw-r--r-- 1 root root 25165824 abr 25 2012 disk
-rw-r--r-- 1 root root 6291968 abr 25 2012 disk.local
-rw-rw-r-- 1 root root 4790624 abr 25 2012 kernel
-rw-rw-r-- 1 nobody nogroup 1856 abr 25 2012 libvirt.xml

Regards

Asunto: RE: [Openstack] Nova and external NFS

Hi:

Thanks for your respond .

This is my /etc /export file in the NFS server:

/export 192.168.111.0/24(rw,sync,no_root_squash,fsid =0)

and my /etc /fstab file in my host is :

<ip nfs server>:/ /nfs-directory nfs4 defaults 0 0

Directories /export and /nfs-directory have 777 permissions

Sorry if I bother you ... but It is driving me crazy

Hi Sergio,
We have environment with external NFS Server, NetAPP, Nexenta, EMC, etc and we haven´t this problem, sounds like a problem with privileges, i can see the libvirt.xml is nobody:nogroup, it is wrong, must be root:root. Try to change manually, but maybe you have a wrong parameter in a configuration that generate this file with this permissions.

Cheers

Asunto: [Openstack] Nova and external NFS

Hello:

I have found some examples to configure NFS in Nova. But all of them use one of the hosts as NFS server. In my case, I need to use an external NFS server, which do not have installed OpenStack .
I have been working on it but I have found some problems . For example : when I created a new instance these are the files that were created :

root@opst1 :~# ll /nfs /NOVA-INST -DIR /instances /instance -00000015/
total 29284
drwxrwxr -x 2 nobody nogroup 4096 abr 25 2012 ./
drwxrwxrwx 4 root root 4096 abr 25 2012 ../
-rw-rw ---- 1 root root 0 abr 25 2012 console.log
-rw -r--r-- 1 root root 25165824 abr 25 2012 disk
-rw -r--r-- 1 root root 6291968 abr 25 2012 disk.local
-rw -rw -r-- 1 root root 4790624 abr 25 2012 kernel
-rw -rw -r-- 1 nobody nogroup 1856 abr 25 2012 libvirt.xml

Instead of libvirt-qemu and kvm , root is the owner of the files.

Please .. help me about it

Thanks a lot ...
