I've got a btrfs file system consisting of 3 devices and using raid1. The file system contains one subvolume "home" which is defined in the fstab and mounted at "/home". fstab entry looks like this:
/dev/sdb3 /home btrfs device=/dev/sdb3,device=/dev/sdc,device=/dev/sda,compress=lzo,subvol=home 0 0
When I open nautilus in 12.04, it lists both "secondary" btrfs devices (sdc and sda) on the left side under "Devices". I can actually mount btrfs system once again when clicking on the icons.
How do I hide those icons in the nautilus?
