Use proper names (i.e. zfs-allow and zpool-add) in NAME subsections of zfs/zpool subcommands instead of current "pretty-printed" ones as makewhatis utilities (or some implementations of it, namely the one from mandoc suite used in FreeBSD) look not only at the document title but also in NAME subsection, adding zfs(8)/zpool(8) to search results which is not correct. (Common sense and other utilities splitting subcommands in multiple man pages, e.g. git, do the same.)

.Dt ZFS-JAIL 8
|
|
.Os FreeBSD
|
|
.Sh NAME
|
|
.Nm zfs-jail
|
|
.Nd Attaches and detaches ZFS filesystems from FreeBSD jails.
|
|
.No A Tn ZFS
|
|
dataset can be attached to a jail by using the
|
|
.Qq Nm Cm jail
|
|
subcommand. You cannot attach a dataset to one jail and the children of the
|
|
same dataset 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. 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. See
|
|
.Xr jail 8
|
|
for information on how to allow mounting
|
|
.Tn ZFS
|
|
datasets from within a jail.
|
|
.Pp
|
|
.No A Tn ZFS
|
|
dataset can be detached from a jail using the
|
|
.Qq Nm Cm unjail
|
|
subcommand.
|
|
.Pp
|
|
After a dataset is attached to a jail and the 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.

|
|
Attaches the specified

|
|
to the jail identified by JID
|
|
.Ar jailid .
|
|
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 functuinality, the jail needs the
|
|
.Va allow.mount
|
|
and
|
|
.Va allow.mount.zfs
|
|
parameters set to 1 and the
|
|
.Va enforce_statfs
|
|
parameter set to a value lower than 2.

See
|
|
.Xr jail 8
|
|
for more information on managing jails and configuring the parameters above.
