⁠12.3.5.1. Preparing Local Storage

Summary

A local storage domain can be set up on a host. When you set up host to use local storage, the host automatically gets added to a new data center and cluster that no other hosts can be added to. Multiple host clusters require that all hosts have access to all storage domains, which is not possible with local storage. Virtual machines created in a single host cluster cannot be migrated, fenced or scheduled.

Important

On Red Hat Enterprise Virtualization Hypervisors the only path permitted for use as local storage is /data/images. This directory already exists with the correct permissions on Hypervisor installations. The steps in this procedure are only required when preparing local storage on Red Hat Enterprise Linux virtualization hosts.

⁠

Procedure 12.6. Preparing Local Storage

On the virtualization host, create the directory to be used for the local storage.
```
# mkdir -p /data/images
```
Ensure that the directory has permissions allowing read/write access to the vdsm user (UID 36) and kvm group (GID 36).
```
# chown 36:36 /data /data/images
```
```
# chmod 0755 /data /data/images
```

Result

Your local storage is ready to be added to the Red Hat Enterprise Virtualization environment.
