attach or detach ZFS filesystem from FreeBSD
- Attach the specified filesystem to the
jail identified by JID jailid or name
jailname. From now on this file system
tree can be managed from within a jail if the
jailed property has been set. To use this
functionality, the jail needs the allow.mount
and allow.mount.zfs parameters set to
1 and the
enforce_statfs parameter set to a value lower
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.
To allow management of the dataset from within a jail, the
jailed property has to be set and the jail
needs access to the /dev/zfs device.
The quota property cannot be changed from
within a jail.
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.
See jail(8) for more information on managing
jails. Jails are a FreeBSD feature and are not
relevant on other platforms.
