What version of mdadm was that from? From mdadm(8) in
mdadm-1.11.0-4.fc4 on my systems:
--assume-clean
Tell mdadm that the array pre-existed and is known to be clean.
This is only really useful for Building RAID1 array. Only use
this if you really know what you are doing. This is currently
only supported for --build.
I tried with --assume-clean, it still wanted to sync. From what my man
page was telling me, it only works with --build. If I use --build it'll
go ahead without syncing, but I need per-device superblocks. Why mdadm
didn't error when I used --assume-clean with --create, I don't know.
