Hi, I am running OpenSolaris 2009.06 snv_111b X86 and encountered some errors when removing a dataset.but her eis the whole story: I tried sharing a ZFS dataset via iscsi following the commands located on http://docs.sun.com/app/docs/doc/820-2313/gechv?l=de <http://docs.sun.com/app/docs/doc/820-2313/gechv?l=de&a=view> &a=view Now I wanted to destroy the dataset and all I get is dataset busy: root at opensolaris:~# zfs destroy performance/iscsi cannot remove device links for ''performance/iscsi'': dataset is busy I disabled the iscsi service and tried to remove the dataset again and the same error message pops up: root at opensolaris:~# svcadm disable svc:/system/iscsitgt:default root at opensolaris:~# zfs destroy performance/iscsi cannot remove device links for ''performance/iscsi'': dataset is busy iscsitadm shows no active targets: root at opensolaris:~# iscsitadm list target I also tried to destroy the whole pool which gives me the exact same error message as before. There are no more dataset in this pool: root at opensolaris:~# zfs list -r performance NAME USED AVAIL REFER MOUNTPOINT performance 100G 813G 20K /performance performance/iscsi 100G 913G 24K - Can anybody tell me how to find out who/what is using this dataset/pool and how to remove the dataset or the whole pool?
