Mounting VxFS as lofs into a non-global zone

VxFS file systems that were previously created in the global zone can be made available in the non-global zone using a loopback file system mount. This functionality is especially useful when the sole purpose of making the file system available in the non-global zone is to share access of this file system with one or more non-global zones. For example, if a configuration file is available in a particular file system and this configuration file is required by the non-global zone, then the file system can be shared with the non-global zone using a loopback file system mount.

The following commands share access of file system /mnt1 as a loopback file system mount with an existing non-global zone newzone:

# zonecfg -z newzone
zonecfg:newzone> add fs
zonecfg:newzone:fs> set dir=/mnt1
zonecfg:newzone:fs> set special=/mnt1
zonecfg:newzone:fs> set type=lofs
zonecfg:newzone:fs> end
zonecfg:newzone> verify
zonecfg:newzone> commit
zonecfg:newzone> exit

The value of dir is a directory in the non-global zone. The value of special is the mount point for the file system inside the local zone.

This mount may be referred later as VxFS loopback mount.
