No, order only matters if you're recreating the array (which is a
last-ditch option for if assembly fails). The metadata on each drive
indicates where it should be in the array, so the assembly will use that
to order the drives.
The fsck errors would look to be genuine issues with the filesystem. Was
the array shut down cleanly before you moved it? You did have to force
the assembly initially, which would suggest not (and could point to some
minor corruption). I'm not sure you have much of an option other than to
go through with a fsck & repair any issues now though (if you've got the
space then I'd suggest imaging the array as a backup though).
Cheers,
Robin
