            Bug ID: 196820
           Summary: IBM x3650, ServeRAID M5110e, volumes corrupted after
                    boot with mrsas driver
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: asmw4@gmx.net

On my IBM x3650 M4, running FreeBSD 10.1-RELEASE I'm using the mfi driver with
the builtin M5110e RAID controller. Then I thought to try the mrsas driver even
the M5110e is not listed in the documentation. I set the 

  hw.mfi.mrsas_enable=1

flag at the loader prompt. Then FreeBSD started, the volumes where listed as
da* devices but I was not able to mount the root filesystem. Then I started the
machine again with mfi enabled. But then I noticed that all volumes are
corrupted, which means that even the GPT was gone. 

The problem seems to be reproducible: A second try had the same result.

I don't know if it's intended that the M5110 should run with mrsas. If not, it
should not damage the volumes. At least there should be a clear warning in the
man page.

The machine is not in production use at the moment, so I can do more testing if
required.

Michael
