|
.Nm zfs
|
|
.Cm jail
|
|
.Ar jailid Ns | Ns Ar jailname

|
.Ar filesystem

|
|
Attach the specified
|
|
.Ar filesystem
|
|
to the jail identified by JID
|
|
.Ar jailid
|
|
or name
|
|
.Ar jailname .
|
|
From now on this file system tree can be managed from within a jail if the
|
|
.Sy jailed
|
|
property has been set.
|
|
To use this functionality, the jail needs the
|
|
.Sy allow.mount
|
|
and
|
|
.Sy allow.mount.zfs
|
|
parameters set to
|
|
.Sy 1
|
|
and the
|
|
.Sy enforce_statfs
|
|
parameter set to a value lower than
|
|
.Sy 2 .
|
|
.Pp
|
|
You cannot attach a jailed dataset's children to another jail.
|
|
You can also not attach the root file system
|
|
of the jail or any dataset which needs to be mounted before the zfs rc script
|
|
is run inside the jail, as it would be attached unmounted until it is
|
|
mounted from the rc script inside the jail.
|
|
.Pp
|
|
To allow management of the dataset from within a jail, the
|
|
.Sy jailed
|
|
property has to be set and the jail needs access to the
|
|
.Pa /dev/zfs
|
|
device.
|
|
The
|
|
.Sy quota
|
|
property cannot be changed from within a jail.
|
|
.Pp
|
|
After a dataset is attached to a jail and the
|
|
.Sy jailed
|
|
property is set, a jailed file system cannot be mounted outside the jail,
|
|
since the jail administrator might have set the mount point to an unacceptable value.
|
|
.Pp
|
|
See
|
|
.Xr jail 8
|
|
for more information on managing jails.

Jails are a
