what ouput you get with

Code: Select all

ls -l /dev/md0

[jungfichte]

Code: Select all

root@(none):/ # ls -l /dev/md0

root@(none):/ #

Still as it can not read mdadm.conf file what happens if you add this option

Code: Select all

mdadm --assemble  --metadata=1.0 /dev/md0 /dev/sda8 /dev/sdb8

[jungfichte]

Code: Select all

root@(none):/ # mdadm --assemble  --metadata=1.0 /dev/md0 /dev/sda8 /dev/sdb8
mdadm: unexpected failure opening /dev/md0
root@(none):/ #

So try this

Code: Select all

mdadm --assemble --config=/sda5/etc/mdadm.conf /dev/md0

or

Code: Select all

mdadm --assemble --force --config=/sda5/etc/mdadm.conf /dev/md0

Now I am no longer at home for the WE.

So if you still fail to assemble the raid1, we will try to destroy it and create it again. As it is a raid1, you can not lost your data.

Anyhow this raid issue can not explain why you fail to get access on the NAS according with boot.log file (web-interface and ssh access ??? <= can you confirm this point)

For this last point, I suggest to do (as I found on the examine output a updatetime on sda8 with an offset of 8min and the boot time saved on boot.log :scratch )

Code: Select all

mv /sda7/boot.log /sda7/boot.log.org

and try to do a standard reboot.

Then stop your NAS and get again a telnet access. So see if you have a new boot.log file on sda7

Code: Select all

ls -l /sda7/boot.log
cat /sda7/boot.log

[jungfichte]

mdadm --assemble --config=/sda5/etc/mdadm.conf /dev/md0
mdadm --assemble --force --config=/sda5/etc/mdadm.conf /dev/md0

Code: Select all

root@(none):/ # mdadm --assemble --config=/sda5/etc/mdadm.conf /dev/md0
mdadm: CREATE user root not found
mdadm: CREATE group root not found
mdadm: unexpected failure opening /dev/md0
root@(none):/ # mdadm --assemble --force --config=/sda5/etc/mdadm.conf /dev/md0
mdadm: CREATE user root not found
mdadm: CREATE group root not found
mdadm: unexpected failure opening /dev/md0
root@(none):/ #

I renamed the the boot.log to boot.log.org as you want.
But the NAS isn't able to boot, yet.
Same behaviour since last time:

When powering on, i can see the hdd leds blinking on the backside and hearing the nas working.
After 10-15 sek. the nas powers off, the hdds spinning down and no hdd-led are lighting.
Only the yellow nic leds are blinking...

So there is no new boot.log :(

Code: Select all

root@(none):/ # ls -l /sda7/boot.log
ls: /sda7/boot.log: No such file or directory

Bye the way there is no important data on the storage.

[Jocko]

ok,

So there is no new boot.log :(

Code: Select all

root@(none):/ # ls -l /sda7/boot.log
ls: /sda7/boot.log: No such file or directory

Do you mount again previously /dev/sda7 ?

Code: Select all

mkdir /sda7
mount /dev/sda7 /sda7

[jungfichte]

Yes,

Code: Select all

root@(none):/ # mkdir /sda7
root@(none):/ # mount /dev/sda7 /sda7
root@(none):/ # ls -l /sda7/boot.log
ls: /sda7/boot.log: No such file or directory
root@(none):/ # cd sda7/
root@(none):/sda7 # ls
