Using Shared QFS With NFS

Note - If you are using NFS v4, you must disable delegations before you can use shared QFS.

Starting with SAM-QFS 5.0 on Oracle Solaris 10 , the Service Management Facility (SMF) is used to manage the mounting of the file system at boot time. If your file system uses NFS, the exact sequence in which you configure NFS and shared QFS is important. If you do not follow the steps in the following procedure, either the shared QFS mount or the NFS share will succeed and the other will fail.

How to Configure Shared Sun QFS With NFS

Export the existing NFS configuration to a file.
The following example exports the configuration into a file /var/tmp/server.xml.
```
# svccfg export /network/nfs/server > /var/tmp/server.xml
```

In the exported file, after the local file system dependency, add a dependency to mount QFS file systems before you NFS share them.

For example:

  <!--
    Must have QFS filesystems mounted before sharing them
  -->
     <dependency name='qfs'
     grouping='require_all'
     restart_on='error'
     type='service'>
     <service_fmri value='svc:/network/qfs/shared-mount:default'/>
     </dependency>

Validate the changes that you made to the file.
```
# svccfg validate /var/tmp/server.xml
```
Disable NFS.
```
# svcadm disable nfs/server
```
Delete the existing NFS server configuration.
```
# svccfg delete nfs/server
```
Import the file that you edited into SMF.
```
# svccfg import /var/tmp/server.xml
```
Enable NFS.
NFS uses the updated file and reads the Sun QFS dependency information.
```
# svcadm enable nfs/server
```

Confirm that the dependency is applied.

# svcs -d svc:/network/nfs/server:default
