5.1.12. Storage within a zone
[dd] Storage can be used in different ways in local zones. The type of use can be classified in the
following ways:
• Device or NFS
− Use thedevice in the local zone directly
• Mount
− The global zone provides a file system per lofs to the local zone
− The global zone mounts a file system when the local zone is booted
− The zone mounts a file system from a device
• Access
− read/write
− read only
− Share writable file system with several zones
5.1.12.1. Using a device in a local zone
[dd] If direct access to a device is required by the local zone, the device must be made available by
the corresponding zone configuration. Once the zone has been restarted, the device entry is available
under /dev, as seen from the local zone.
global# zonecfg -z zone1
zonecfg:zone1> add device
zonecfg:zone1:device> set match=/dev/rdsk/c1d0s0
zonecfg:zone1:device> end
zonecfg:zone1> info device
device:
match: /dev/rdsk/c1d0s0
zonecfg:zone1> commit
zonecfg:zone1> exit
5.1.12.2. The global zone supplies a file system per lofs to the local zone
[dd] /export/globalhome of the global zone is to be mounted as writable in the local zone as
/export/home. Since /export/globalhome is already available in the global zone, the file
system can be added as a loopback filesystem. If the loopback filesystem is mounted as writable,
both the global zone as well as zone1 can write on the file system.
global# zonecfg -z zone1
zonecfg:zone1> add fs
zonecfg:zone1:fs> set special=/export/globalhome
zonecfg:zone1:fs> set dir=/export/home
zonecfg:zone1:fs> set type=lofs
zonecfg:zone1:fs> add options rw
zonecfg:zone1:fs> info
fs:
dir: /export/home
special: /export/globalhome
raw not specified
type: lofs
options: [rw]
zonecfg:zone1:fs> end
zonecfg:zone1>
