Adding and removing ZFS filesystems in Zones

I have a Solaris 10 container that is running on ZFS filesystems being presented from the Global Zone.

I have a filesystem presented to the Local zone and my user wants me to remove it.

It there any way I can remove this while the zone is running?

I tried unmounting it from the local zone and the global zone, all say device is busy. And I know I have to go into zonecfg and get it out of there too..

Any suggestions to remove this filesystem from a running zone?

NAME
amzfs-sendrecv - Amanda script to create zfs sendrecv DESCRIPTION
amzfs-sendrecv is an Amanda application implementing the Application API. It should not be run by users directly. It create a zfs snapshot of the filesystem and backup the snapshot with 'zfs send'. Snapshot are kept after the backup is done, this increase the disk space use on the client but it is neccesary to be able do to incremental backup. If you want only full backup, you can disable this feature by setting the KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete backup is allowed, it is impossible to restore a single file. The application is run as the amanda user, it must have many zfs priviledge: zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM Some system doesn't have "zfs allow", but you can give the Amanda backup user the rights to manipulate ZFS filesystems by using the following command: usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER This will require that your run zfs under pfexec, set the PFEXEC property to YES. The format of the diskdevice in the disklist (DLE) must be one of: Desciption Example ---------- ------- Mountpoint /data ZFS pool name datapool ZFS filesystem datapool/database ZFS logical volume datapool/dbvol The filesystem doesn't need to be mounted. PROPERTIES
This section lists the properties that control amzfs-sendrecv's functionality. See amanda-applications(7) for information on the Application API, application configuration. DF-PATH Path to the 'df' binary, search in $PATH by default. KEEP-SNAPSHOT If "YES" (the default), snapshot are kept after the backup, if set to "NO" then snapshot are no kept and incremental backup will fail. ZFS-PATH Path to the 'zfs' binary, search in $PATH by default. PFEXEC-PATH Path to the 'pfexec' binary, search in $PATH by default. PFEXEC If "NO" (the default), pfexec is not used, if set to "YES" then pfexec is used. EXAMPLE
In this example, a dumptype is defined to use amzfs-sendrecv application to backup a zfs filesystem. define application-tool amzfs_sendrecv { comment "amzfs-sendrecv" plugin "amzfs-sendrecv" #property "DF-PATH" "/usr/sbin/df" #property "KEEP-SNAPSHOT" "YES" #property "ZFS-PATH" "/usr/sbin/zfs" #property "PFEXEC-PATH" "/usr/sbin/pfexec" #property "PFEXEC" "NO" } define dumptype user-zfs-sendrecv { program "APPLICATION" application "amzfs_sendrecv" } SEE ALSO
