Storage domain

Configure nfs Stora

OVirt cluster has two methods: local storage and shared storage. When local storage is selected, only a single Node node can be added to the cluster. Therefore, in order to make better use of the cluster characteristics, nfs shared storage is adopted. Configure nfs shared storage on each Node node to install virtual machines, and execute the following command:

# mkdir / export/iso # create an iso storage domain to store system images

# mkdir / export/data # create a data storage domain for storing virtual machine data

# chown 36:36-R / export # Grant VDSM permission

# chmod 0755-R / export # Grant execution permission

# cat / etc/exports # Edit the exports file as follows

# / export/ iso * (rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

# / export/data * (rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

# systemctl enable-- now nfs.service # Boot and start immediately

Add NFS Stora

Create a new oVirt storage domain to store data in the data storage domain management interface, and then create a new ISO storage domain to store virtual machine images, and fill in the correct storage path and other information according to the page prompts.
