-For some reason, Thunar will sometimes show LVM2 physical volumes as removable devices. As an example, with Ubuntu 12.04 and Xfce using an encrypted disk that then contains a LVM2 physical volume, that volume will come visible even when it isn't mountable. The solution involves using the UDISKS_PRESENTATION_HIDE environment variable. However, this needs to be passed to Thunar using udev.\\+For some reason, Thunar will sometimes show LVM2 physical volumes as removable devices.

-Adding the following in ///etc/udev/rules.d/99-hide-thunar-devices.rules// will hide devices starting with "mdand ending with "_crypt", essentially hiding encrypted raid devices.+Adding the following in ///etc/udev/rules.d/99-hide-thunar-devices.rules// will the device "md1"
 <code> <code>
-ENV{DM_LV_NAME}=="md?*_crypt", ENV{UDISKS_PRESENTATION_HIDE}:="1"+KERNEL=="md1", ENV{UDISKS_PRESENTATION_HIDE}="1"
 </code> </code>
  
-Alternative syntax if you know the exact device name:+Then use this command (as root) to trigger a refresh:
  
 <code> <code>
-KERNEL=="sda1", ENV{UDISKS_PRESENTATION_HIDE}:="1"+udevadm trigger
 </code> </code>
  
-The bad news: a reboot seems to be needed.+You may need to play around guessing the correct device name depending on your setup. Udisks doesn't appear to be able to tell you directly which the possible mystery device is.
