    just playing with ZFS for learning and i have couple of Iscsi and NFS
    enabled on zfs pool named acipool.
    when ever i tried to export the pool for testing purposes it says. "pool is
    bussy"

    actually i am testing multiple scenarios in one go.
    i have replace the drives with bigger ones and want to check if
    autoexpend=on is working. though it is not working automatically. so some
    where in google it is written that, force online the devices with -e option
    and export then import will do that job. and also do not want to delete the
    Iscsi Zvol because, i do not want data loss. and i also want to try the
    import tool said by ZFS that it will auto import the whole raid with out
    problem with all the data in it. so just wana try that magice. but for now
    i am stuck at the point where i can not export pool.

    i disabled iscsi service
    disabled       14:13:35 svc:/network/iscsi/initiator:default
    disabled       14:13:45 svc:/network/iscsi/target:default

    i tired this but no help
    root at omni:/export# zpool export acipool
    cannot export 'acipool': pool is busy
    root at omni:/export# zpool export -F acipool
    cannot export 'acipool': pool is busy
    root at omni:/export# zpool export -f acipool
    cannot export 'acipool': pool is busy

    here is my zfs list
