            Bug ID: 225997
           Summary: "mfiutil show volumes" incorrectly identifies RAID-1
                    vs RAID-10 volumes
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: yaneurabeya at gmail.com

Based on the math shown below (and my knowledge of the configuration), my
configuration is being misreported as RAID-1 (in reality it's RAID-10):

# mfiutil show volumes                                                          
mfi0 Volumes:                                    
  Id     Size    Level   Stripe  State   Cache   Name                           
 mfid0 ( 5588G) RAID-1      64K OPTIMAL Disabled 
# sudo mfiutil show drives
mfi0 Physical Drives:
