The Mount agent provides loopback file system support. You can manage the loopback file system as a Mount resource. You can use this loopback support to mount a file system in the global zone and share it in non-global zones. For loopback support, configure the FSType attribute to use a value of lofs.

The following is a sample configuration where you use the Mount resource to manage the lofs file system:
group loopbacksg ( SystemList = { sysA = 0, sysB = 1 } ContainerInfo@sysA = { Name = zone1, Type = Zone, Enabled = 1 } ContainerInfo@sysB = { Name = zone1, Type = Zone, Enabled = 1 } ) Mount lofs_mnt_global_to_local ( MountPoint = "/export/home/zone1/root/lofs_mnt" BlockDevice = "/mnt1/m1" FSType = lofs ) Zone z1 ( ) Mount base_mnt ( MountPoint = "/mnt1" BlockDevice = "/dev/vx/dsk/tdg/tvol1" FSType = vxfs FsckOpt = "-y" ) lofs_mnt_global_to_local requires z1 lofs_mnt_global_to_local requires base_mnt
