But yes, it doesn't hurt to add it to a wiki page somewhere.

I added this text to the wiki:

"There are bugs in older versions of mdadm, and a lot of "stable" operating
system releases ship with really old mdadm versions. Recent versions are 3.2.x
and 3.3.x. It's advisable if you run into problems assembling your raid to
upgrade to the latest git version of mdadm. If you can get the raid to
successfully assemble and recover with the git version, then it's fine to use
your old mdadm version again for normal system operation. Newer mdadm doesn't
make any changes to the array that isn't backwards compatible."

That ought to help the dummies out...

  As follow-up and confirmation of the help statement. I can confirm that after
repairing my arrays under mdadm 3.3.2, I was able to reboot and have the arrays
assemble and run with mdadm 2.6.4 without any issue. (good thing since the
problem was on the / partitions...)

  Now I just have to back-port mdadm-master to build and run on openSuSE 11.0
when the closest thing I can find is an 11.1 src.rpm. (should be close enough)

  Thank you again Neil and Mikael for all the help.
