jail
jailid|jailname
filesystem
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 than
2.
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. | |
