Hi, I don't know what causes this, but while stopping one of jails I also run zfs inherit mountpoint on this jails fs. This jail was in stopping state at this moment. Process than hanged in D state. Then I was doing some stuff on the server, and while "zfs unmount -f" of that fs, server chrased. Now everytime I wan't to unmount that fs process hang. I've managed to send & receive this fs to other fs and mounted sucessfuly. Before I reboot and try to destroy this fs, here is output of procstat -k PID (zfs umount zroot/myfs) PID TID COMM TDNAME KSTACK 3937 100559 zfs - mi_switch sleepq_timedwait _sleep zfs_zget zfs_get_data zil_commit zfs_freebsd_write VOP_WRITE_APV vnode_pager_generic_putpages vnode_pager_putpages vm_pageout_flush vm_object_page_collect_flush vm_object_page_clean vm_object_terminate vnode_destroy_vobject zfs_freebsd_reclaim vgonel vflush Is there anything I can check or is this know bug? Server is running on 9.1-RELEASE regards Uros
