Mounting File Systems in Zones

When file systems are mounted from within a zone, the nodevices option applies. For example, if a zone is granted access to a block device (/dev/dsk/c0t0d0s7) and a raw device (/dev/rdsk/c0t0d0s7) corresponding to a UFS file system, the file system is automatically mounted nodevices when mounted from within a zone. This rule does not apply to mounts specified through a zonecfg configuration.

Options for mounting file systems in non-global zones are described in the following table. Procedures for these mounting alternatives are provided in Configuring, Verifying, and Committing a Zone and Mounting File Systems in Running Non-Global Zones.

Any file system type not listed in the table can be specified in the configuration if it has a mount binary in /usr/lib/fstype/mount.

File System	Mounting Options in a Non-Global Zone
AutoFS	Cannot be mounted using `zonecfg`, cannot be manually mounted from the global zone into a non-global zone. Can be mounted from within the zone.
CacheFS	Cannot be used in a non-global zone.
FDFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
HSFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
LOFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
MNTFS	Cannot be mounted using `zonecfg`, cannot be manually mounted from the global zone into a non-global zone. Can be mounted from within the zone.
NFS	Cannot be mounted using `zonecfg`. V2, V3, and V4, which are the versions currently supported in zones, can be mounted from within the zone.
PCFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
PROCFS	Cannot be mounted using `zonecfg`, cannot be manually mounted from the global zone into a non-global zone. Can be mounted from within the zone.
TMPFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
UDFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
UFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone.
XMEMFS	Can be mounted using `zonecfg`, can be manually mounted from the global zone into a non-global zone, can be mounted from within the zone. Support for this file system is being removed from the Solaris system in a future release.
ZFS	Can be mounted using the `zonecfg` `dataset` and `fs` resource types.
