40Storage Foundation and High Availability Solutions support for Solaris ZonesDirect mount of VxFS file systems from global zoneDirect mount of VxFS file systems from global zoneExclusive access of a VxFS file system can be delegated to a non-global zone bydirect mounting the file system in the non-global zone. Using direct mounts limitsthe visibility of and access to the file system to only the non-global zone that hasdirect mounted this file system.See “Mounting a VxFS file system in a non-global zone” on page 40.See “Adding a direct mount to a zone's configuration” on page 41.See “Creating VxFS file systems inside non-global zones” on page 42.Mounting a VxFS file system in a non-global zoneTo direct mount a VxFS file system in a non-global zone, the directory to mountmust be in the non-global zone and the mount must take place from the globalzone. The following procedure mounts the directory dirmnt in the non-globalzone myzone with a mount path of /zonedir/myzone/root/dirmnt.Note: VxFS entries in the global zone /etc/vfstab file for non-global zone directmounts are not supported, as the non-global zone may not yet be booted at thetime of /etc/vfstab execution.Once a file system has been delegated to a non-global zone through a direct mount,the mount point will be visible in the global zone through the mount command,but not through the df command.To direct mount a VxFS file system in a non-global zone1 Log in to the zone and make the mount point:global# zlogin myzonemyzone# mkdir dirmntmyzone# exit2 Mount the file system from the global zone:■Non-cluster file system:global# mount -F vxfs /dev/vx/dsk/dg/vol1 /zonedir/zone1\/root/dirmnt■Cluster file system:
