I got pointed to this forum from this thread (http://forum.nas-portal.org/showthread. ... -Laufwerke) by Mijzelf.
Since I don't expect you all speak german I will gladly give you a short summary of what happend:
- lacie support is the best (*haha*)
- I have a Lacie 5big Network 2, with 15 TB, and RAID 5, age about 1 year
Suddenly overnight one disk showed as "missing" in the dashboard, I just unplugged the disk and put it back in and the raid array was rebuilt. After that I had access to my data for about 10 minutes. Then access was gone again - but RAID array still showed as "healthy". My whole dashboard interface was (and is) very slow and showed weired stuff (for example no IP address or 0.0.0.0 as IP and so on). Suddenly 2 disks where shown as missing, I just rebooted the NAS and tadaaa RAID Array ways healthy again. Then as a next step, according to the lacie support ,I reseted the device (without data loss) and 1 disks (its always the "middle" one by the way) was missing again, after another reboot 2 disks were missing, after another reboot 3 disks were missing and then again only the one in the middle.
Seems legit to me.
Anyway what I now did is:
I downloaded the fvdw-sl-console and loaded the standalone kernel.
Then I tried some things from here (http://www.plugout.net/viewtopic.php?f=4&t=1412) but didn't want to go any further since I don't really know what I'm doing :)

And I already uploaded mdadm with tftp - so I would be ready to use it if needed.
Any help would be appreciated :) You can also just point me to the other thread if I have do to the exactly same things.
