I have an VT6410 RAID controller, 2 disk attached to it in a mirror (RAID 1). When I install Ubuntu 8.04 I found two items in Places menu to mount this two disks. When I mount one of them and write something to it, data are written only to this particular disk and not to another one (mirror is not working). So I use dmraid to create new mount point for mirror (I use this guide: http://ubuntuforums.org/archive/index.php/t-2557.html). Now I have new item in Places and when I mount this, writing works fine (data are present on both disks). Mounting previous two items in Places stops working with error: fuse: mount failed: Device or resource busy So my question is, how to remove first two items from Places?
