While I don't know your mapper layout, trim working on the others but not on /home sounds to me like either one of the physical devices on which /home is located doesn't support trim, or they all do, but somewhere along the line that information is being lost, so it doesn't believe trim can actually work on that filesystem. Typical shortcut "the information available says that can't work, simply return before trying" behavior. -- Duncan - List replies preferred. No HTML msgs.
