[Users] exception occured when adding NFS storage

Thu Jul 11 14:37:13 UTC 2013

Hi Sandro,

I do see:
# cat /etc/selinux/targeted/modules/active/file_contexts.local
# This file is auto-generated by libsemanage
# Do not edit directly.
/mnt/iso(/.*)?    system_u:object_r:public_content_rw_t:s0
/mnt/data(/.*)?    system_u:object_r:public_content_rw_t:s0

# getenforce
Permissive

But I still failed to create a storage domain on the ovirt.engine side and got the same exception errors, and also vdsm is idle during the creation of storage domain.

Here is the setup for ovirt.engine:
oVirt Engine will be installed using the following configuration:
=================================================================
override-httpd-config:         yes
http-port:                     80
https-port:                    443
host-fqdn:                     ovirt.engine
auth-pass:                     ********
org-name:                      ovirt
application-mode:              both
default-dc-type:               NFS
db-remote-install:             local
db-local-pass:                 ********
nfs-mp:                        /mnt/iso
config-nfs:                    yes
override-firewall:             IPTables
Proceed with the configuration listed above? (yes|no): yes

Thanks,
Hongyi

Hi,

I started to learn the oVirt by following the oVirt Quick Start Guide.

I used one server as the ovirt.engine, and another server as the ovirt.host. Both servers run Fedora 18.

After executing the command "engine-setup" in the ovirt.engine, I can get into the admin portal to start the configuration of host, storage, etc. Here was what I am doing:

1.       In the Default data center, I clicked  the Guide Me icon. The first thing is to configure the host. After waiting for 4-5 minutes, I saw the host ovirt.host is displayed under the Host tab with the Up status.

2.       On the ovirt.engine server, I did the following before creating the storage:

mkdir -p /mnt/data

chown -R 36:36 /mnt/data

Add the following line to /etc/sysconfig/nfs:

    NFS4_SUPPORT="no"

Add the following line to /etc/exports:

   /nmt/data  *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

systemctl restart nfs-server.service

Well, exports has a typo error: /nmt/data instead of /mnt/data
If that it's not enough, If you're using selinux ensure that /mnt/data has the correct context:

/etc/selinux/targeted/modules/active/file_contexts.local:
/mnt/data(/.*)?    system_u:object_r:public_content_rw_t:s0

3.       Back to the Default data center, clicked the Guide Me icon to start the configuration of new storage.

4.       On the New Storage dialog, set Name field to be NFS-Share, and set the Export Path field to be ovirt.engine:/mnt/data. Then click OK

After couple of minutes, I saw the error window popped up: Error: Cannot add Storage. Internal error, Storage Connection doesn't exist.

>From the /var/log/ ovirt-engine/engine.log, I can see:

Please let me know what I was doing wrong.

Thanks,

Hongyi

P.S. If I create the NFS domain in the ovirt.host side (i.e., Export Path is ovirt.host:/mnt/data), then everything is okay. Not sure why failed on the ovirt.engine side.
