Hello All,

I keep getting this problem when attaching the iso-domain.

I started from scratch.

Configured engine

configured /connected a Centos7 host

This time I did the nfs-export on that Centos7 host more carefully.

Exports are /export/data export/iso export/import_export
[root@localhost ~]# ls -la /export/
totaal 4
drwxr-xr-x. 5 vdsm kvm    47 29 okt 13:35 .
drwxr-xr-x. 19 root root 4096 29 okt 13:35 ..
drwxr-xr-x. 3 vdsm kvm    74 29 okt 14:52 data
drwxr-xr-x. 2 vdsm kvm     6 29 okt 13:35 import_export
drwxr-xr-x. 2 vdsm kvm     6 29 okt 13:35 iso

they can be mounted with command
mount -t nfs 192.168.80.168:/export/import_export /mnt/test

on the engine or any other station in the network without em.

I added an New ( nfs ) domain with export path :
192.168.80.168:/export/data

All went without em.

I now have Data Master NFS V3 Active 47 GB 44 GB

Still when trying to attach iso, I get em in tail -f /var/log/ovirt-engine/engine.log -------> see below.

Thanks for any help. Greetings, J.

Hello All,

indeed, I made a subnet error.
I 've now changed the ip address of the host, that took me some searching.
Now I'm working on re-doing the nfs setup.

Greetings, J.

2015-10-20 16:14 GMT+02:00 Fred Rolland <frolland@redhat.com>:
Hi,

Also can you check the log on the host for more information ?
The VDSM log is here: /var/log/vdsm/vdsm.log

Are you sure you can connect to nfs server from your host ? Check for firewall/iptables configuration maybe...

Regards,

Fred

Hello All,

following the Ovirt quick start guide, I
attached a host and configured nfs-storage.
Now when trying to connect the ( standard ) iso-domain I get an EM:

Here's more output from /var/log/ovirt-engine/server.log:
