After some frustration with RAID-5 finding mismatches and not being able to figure out which drive has the problem, I'm setting up a rather intricate 5-way mirrored (x 2-way striped) system.
Out of interest, what systems are you seeing mismatches on? Most of the ones I've seen are on LSI1068* SAS controllers (with SATA drives, but not sure if that counts for anything, don't use many SAS drives) including the Dell SAS5* and SAS6* series. I suspect there are some corner cases where they corrupt data on disk. Should open a kernel.org bug really, so that LSI can ignore the issue in public...
