I was trying to use mdadm --wait a bit ago to wait for a recovery

Here is md12 after adding /dev/sdf1 back to it.

However, mdadm /dev/md12 --wait (and --wait-clean) did not wait for
the recovery to be complete.
turnip:~ # mdadm /dev/md12 --wait
turnip:~ # echo $?
0
turnip:~ # mdadm --version
mdadm - v3.0 - 2nd June 2009
I would --fail and --remove /dev/sdf1 and try again (with --add), and
I did this several times, and I could not get it to wait until the
recovery was complete.
Am I doing something wrong? Did I mis-read the documentation?
Did you try `mdadm --wait /dev/md12`? For me that returns 1 on a
fully-up array (where there's nothing to wait for) while `mdadm
/dev/md12 --wait` returns 0, so they're obviously handled differently. I
don't really feel like degrading an array to test further, I'll leave it
to you :-)
Cheers,
John.
