3.3. Migrating the ISO Domain


This procedure shows you how to migrate the ISO domain from RHEV-M 3.6 to 4.0, using the iso_domain.tar.gz backup file that you created in Section 3.2, “Upgrading to Red Hat Virtualization Manager 4.0”.

Note

The ISO domain should not be in the Manager virtual machine.
  1. Create an export directory and set its permissions:
    # mkdir -p /var/lib/exports/iso
    # chown -R 36:36 /var/lib/exports/
    Copy to Clipboard Toggle word wrap
  2. Extract the ISO domain backup to this directory:
    # cd /var/lib/exports/iso
    # tar zxf iso_domain.tar.gz
    Copy to Clipboard Toggle word wrap
  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/
    Copy to Clipboard Toggle word wrap
  4. Create /etc/exports.d/ovirt-engine-iso-domain.exports with the following line:
    /var/lib/exports/iso  *(rw)
    Copy to Clipboard Toggle word wrap
  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"
    
    Copy to Clipboard Toggle word wrap
  6. Enable the nfs service:
    # systemctl enable nfs
    # systemctl start nfs
    
    Copy to Clipboard Toggle word wrap
  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
