5.9. Migrating the ISO Domain from 3.6

Migrate the ISO domain from 3.6 to the current version of Red Hat Virtualization, using the iso_domain.tar.gz backup file that you created during the upgrade from 3.6 to 4.0.

Important

The new directory for the ISO domain must not be on the Manager machine.

Note

The ISO domain is deprecated in Red Hat Virtualization 4.2, and will be removed in a future version. Red Hat recommends uploading ISO images to a data storage domain. See Uploading Images to a Data Storage Domain in the Administration Guide.

  1. Create an export directory on the storage server and set its permissions: 

    # mkdir -p /var/lib/exports/iso
# chown -R 36:36 /var/lib/exports/

  2. Extract the ISO domain backup to this directory: 

    # cd /var/lib/exports/iso
# tar zxf iso_domain.tar.gz

  3. Set the SELinux context for the files in the export directory: 

    # chcon -R system_u:object_r:public_content_rw_t:s0 /var/lib/exports/iso/

  4. Create /etc/exports.d/ovirt-engine-iso-domain.exports with the following line: 

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

  5. Edit the following lines in /etc/sysconfig/nfs: 

    RPCMOUNTDOPTS="-p 892"
(..snip..)
STATDARGS="-p 662 -o 2020"
(..snip..)
LOCKD_UDPPORT=32769
LOCKD_UDPPORT=32803
RPCRQUOTAOPTS="-p 875"

  6. Enable the nfs service: 

    # systemctl enable nfs
# systemctl start nfs

  7. Allow services and ports with firewalld: 

    # firewall-cmd --add-service={nfs,rpc-bind}
# firewall-cmd --add-service={nfs,rpc-bind} --permanent
# firewall-cmd --add-port={32769/udp,32803/tcp,662/tcp,662/udp,875/tcp,875/udp,892/tcp,892/udp}
# firewall-cmd --add-port={32769/udp,32803/tcp,662/tcp,662/udp,875/tcp,875/udp,892/tcp,892/udp} --permanent

  8. In the Administration Portal, update the ISO domain’s storage path:

    1. Click Storage → Domains.
    2. Click the ISO domain’s name to go to the details view.
    3. Click the Data Center tab and click Maintenance.
    4. When the ISO domain is in maintenance mode, click Manage Domain.
    5. Change the Export Path to point to the new directory, for example: storage.example.com:/var/lib/exports/iso
    6. Click OK.
