Mounting File Systems in Running Non-Global Zones
You can mount file systems in a running non-global zone. The following procedures are covered.
As the global administrator in the global zone, you can import raw and block devices into a non-global zone. After the devices are imported, the zone administrator has access to the disk. The zone administrator can then create a new file system on the disk and perform one of the following actions:
Mount the file system manually
Place the file system in /etc/vfstab so that it will be mounted on zone boot
As the global administrator, you can also mount a file system from the global zone into the non-global zone.
How to Import Raw and Block Devices by Using zonecfg
This procedure uses the lofi file driver, which exports a file as a block device.
Become superuser, or assume the Primary Administrator role.
To create the role and assign the role to a user, see "Using the Solaris Management Tools With RBAC (Task Map)" in System Administration Guide: Basic Administration.
Change directories to /usr/tmp.
global# cd /usr/tmp
Create a new UFS file system.
global# mkfile 10m fsfile
Attach the file as a block device.
The first available slot, which is /dev/lofi/1 if no other lofi devices have been created, is used.
global# lofiadm -a `pwd`/fsfile
You will also get the required character device.
Import the devices into the zone my-zone.
global# zonecfg -z my-zone zonecfg:my-zone> add device zonecfg:my-zone:device> set match=/dev/rlofi/1 zonecfg:my-zone:device> end zonecfg:my-zone> add device zonecfg:my-zone:device> set match=/dev/lofi/1 zonecfg:my-zone:device> end
Reboot the zone.
global# zoneadm -z my-zone boot
Log in to the zone and verify that the devices were successfully imported.
my-zone# ls -l /dev/*lofi/*
You will see a display that is similar to this:
brw------- 1 root sys 147, 1 Jan 7 11:26 /dev/lofi/1 crw------- 1 root sys 147, 1 Jan 7 11:26 /dev/rlofi/1

For more information, see the lofiadm(1M) and lofi(7D) man pages.
How to Mount the File System Manually
You must be the zone administrator and have the Zone Management profile to perform this procedure. This procedure uses the newfs command, which is described in the newfs(1M) man page.
Become superuser, or have the Zone Management rights profile in your list of profiles.
In the zone my-zone, create a new file system on the disk.
my-zone# newfs /dev/lofi/1
Respond yes at the prompt.
newfs: construct a new file system /dev/rlofi/1: (y/n)? y
You will see a display that is similar to this:
/dev/rlofi/1: 20468 sectors in 34 cylinders of 1 tracks, 602 sectors 10.0MB in 3 cyl groups (16 c/g, 4.70MB/g, 2240 i/g) super-block backups (for fsck -F ufs -o b=#) at: 32, 9664, 19296,Check the file system for errors.
my-zone# fsck -F ufs /dev/rlofi/1
You will see a display that is similar to this:
** /dev/rlofi/1 ** Last Mounted on ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups 2 files, 9 used, 9320 free (16 frags, 1163 blocks, 0.2% fragmentation)
Mount the file system.
my-zone# mount -F ufs /dev/lofi/1 /mnt
Verify the mount.
my-zone# grep /mnt /etc/mnttab
You will see a display similar to this:
/dev/lofi/1 /mnt ufs rw,suid,intr,largefiles,xattr,onerror=panic,zone=foo,dev=24c0001 1073503869
How to Place a File System in /etc/vfstab to Be Mounted When the Zone Boots
This procedure is used to mount the block device /dev/lofi/1 on the file system path /mnt. The block device contains a UFS file system. The following options are used:
logging is used as the mount option.
yes tells the system to automatically mount the file system when the zone boots.
/dev/rlofi/1 is the character (or raw) device. The fsck command is run on the raw device if required.
