It hasn't changed since the first write when the reshape started.
That means there is no write happening on the root file which was chosen
for backup.
Just a check, for sanity, I hope the root partition is not filled up.

1. your mdstat says that sdb1 device is down. However, examine says sdb1
seems OK. I am not sure why?
Could you check for the daemon(process) running for md0 and see the
strace of it. Where is it waiting?
Also I would want to check, what have been the last few dmesg in your
system, any updated since the resyncing/reshaping started, as you shared
in the last mail.
I am looping in to Phil explicitly for some help here.
@Phil,
Need some help here!

Anugraha Sinha
