ZFS-JAIL(8) System Manager's Manual ZFS-JAIL(8) NAME zfs-jail -- attach or detach ZFS filesystem from FreeBSD jail SYNOPSIS zfs jail jailid|jailname filesystem zfs unjail jailid|jailname filesystem DESCRIPTION zfs 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 pa- rameters 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 de- vice. 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. zfs unjail jailid|jailname filesystem Detaches the specified filesystem from the jail identified by JID jailid or name jailname.
