Three questions -

1. What does the stuff about "metadata format 1.10 unknown" mean?
Notice the "super 1.1" vs. "metadata 1.01" vs. "metadata format 1.10"
disrepancy between mdsat, --detail and --grow output.

2. Am I doing something wrong? :)

3. How can I get more info about what is causing the failure to
initialize the growth?

Thanks!

mdadm. I hope that isn't rude of me.)

I thought there were three metadata variants for 1.x: 1.0 1.1 and 1.2
 Maybe the extra 1 or 0 at the end refers to a reshape in progress?

Thanks for the reply. FWIW, I intended the array to have metadata
format 1.1 when I created it. I've noticed these "1.01" messages
before, so I believe it's not due to the reshape. However, I'm
thinking the funny metadata might be interfering with the reshape
somehow.

	I'm getting the same thing on one of my systems and not on the
other:
