Hello

I've a problem with my raid0.
The probelmatic disks (2x 1TB wdred) were in usage in my server, now
they got replaced with 3x 4TB seagate in a raid5.

Before I turned them off, I made a backup on an external drive (normal
hdd via USB) via rsync -avx /source /mnt/external/

Whatever happens in the night, the backup isn't complete and I miss files.
So I put the old raid again into the server and wanted to start, but the
Intel Raid Controller said that one of the disks are no member of a raid.

My server mainboard is from Gigabyte a MX11-PC0.

Well I made some mdadm examines, smartctl, mdstat, lsdrv logfiles and
attached them to the mail.

At the moment I have both raid0 disks, the backup disk and my normal ssd
in my workstation.
My workstation has this OS:
nara@Nibler:~$ cat /etc/os-release

I would be very glad when someone can help me with this issue.
All I want is to localy mount the raid0 for getting my files and do a
new fresh rsync via SATA and not USB.

Thank you
