I just tried reimporting my old storage domains but that doesn't seem to
work:

[root at server data]# pwd
/raid/ovirt-old/data
[root at server data]# ls
1979444d-b79a-494c-8c1a-bcc132e31a04  __DIRECT_IO_TEST__

This is the old data domain I  used, and the
1979444d-b79a-494c-8c1a-bcc132e31a04 contains quite a lot of VMs.

When going to the webinterface and doing :
- Storage
- Import domain
    - Type: NFS
    - export path: $IP:/raid/ovirt-old/data (and
$IP:/raid/ovirt-old/data/1979444d-b79a-494c-8c1a-bcc132e31a04)

Of course I created an entry in /etc/exports in order to be able to
mount this domain by NFS:


[root at leiden data]# exportfs 
/raid/ovirt       192.168.1.44/255.255.255.255
/raid/ovirt-old
        192.168.1.44/255.255.255.255


And ownership is by user vdsm.

Despite of this it doesn't work. Unfortunately this page
(http://www.ovirt.org/Features/Import_an_existing_Storage_Domain) isn't
of much use either.

How should I do this?

Cheers,

Boudewijn
