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 a directory in the global zone to be mounted in the non-global zone.
