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.
- Create an export directory and set its permissions:
# mkdir -p /var/lib/exports/iso # chown -R 36:36 /var/lib/exports/
- Extract the ISO domain backup to this directory:
# cd /var/lib/exports/iso # tar zxf iso_domain.tar.gz
- 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/
- Create
/etc/exports.d/ovirt-engine-iso-domain.exportswith the following line:/var/lib/exports/iso *(rw)
- 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"
- Enable the
nfsservice:# systemctl enable nfs # systemctl start nfs
- 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
