Hello there.
I did something wrong.
I tried to get a disk out of a RAID5 with 8 hdds (4TB) to get a Hotspare
to change to RAID6 afterwards.
The RAID was clean and not rebuilding before I started.
The partition was only 11TB big. Not yet resized, because not created
with 64Bit, which I wanted to do afterwards.
Therefore I issued the following commands:
mdadm --grow -n7 /dev/md1 <-- just to get the size for the next command.
mdadm --grow /dev/md1 --array-size 23441292288
mdadm --grow -n7 /dev/md1 --backup-file /var/backups/mdadm.backup
The RAID /dev/md1 is mounted on /srv, so the backupfile is safe.
After a some time, someone told me, that seafile does not work. Since I
was in a hurry, I just rebootet the server and forgot the RAID rebuild.
The server came up again, but without /dev/md1.
I had made a Backup, which is 2 days old. Not so bad, because I have the
seafile data on several computers. But to get the RAID back to work
would be better.
How do I restart the rebuild process with the backup-file?
This is what I get in the console:

Okay, quick response here. Won't do any damage, might work.
Stop and reassemble the array ...
mdadm --stop /dev/md1
mdadm --assemble --scan
What you describe sounds like something tried to start the array while
it was half-assembled. There's a bunch of interactions between udev,
systemd, and mdadm, which seem to get badly off-kilter if something
hiccups anywhere.
My suggestion won't do any harm - it might fix the problem, and it'll
give the experts the chance to chime in.
Cheers,
Wol

I'm a bit confused here.
You started out with 8 disk RAID-5? And final result is to be what?
RAID-6 with 8 disks?

I'm not sure, but you might not have needed any of these intermediate steps.
But now you started it you might have to finish them.
That said there is a reshape revert (which is not yet in the manpage?)
which might help if the regular reshape just won't resume.

It says busy because already assembled (or in use by something else).
So you have to stop first before assembeling again.
I didn't see anything out of place in your --examine.
It seems to be in sync, event count identical, ....
Good luck

Correct.

Hmmm. Had RAID5 with 8 disks. To convert to RAID6 you need a Hotspare,
but all my drive-cage is full.

Yes. That info would help.
