Post HELP: Nas Not Booting 
 
I could really use some advice..
as from today i'm unable to connect to my nas. Yesterday I copied for about 250gb of moviefiles to it without any probs, and I could stream them to my dreambox.
Today i have no acces to it, I don't find it on the network, i used a port scanner to scan the entire subnet. Zero results!
when removing the disks and rebooting i still couldn't find anything. But after pressing the reset button, I found it on 192.168.123.205 (resetting caused the device to receive ip from dhcp) keeping the default settings and reconnecting the disks. Results again in not finding the nas.

Anyone has any ideas?

in the meantime I connected a serial adapter and could successfully communicate with the device.

I'll attach two log files:
-one where no hdd was connected
-one where both hdd are connected

I assume I have a problem on my hdd's but why  and how to fix it?

If you connect HDDs directly to a PC, are disks found and is content shown?
Are they RAID0, RAID1, other?

Don't know I didn't try to hook them up to another device. But I will give it a try (don't i need to use some software to see the file format?)

They are set in raid, don't know which number... but they should backup eachother (21tb=1tb)

Another thing i noticed the other day when browsing from my Android tablet, next to the usual md1 folder there was now also a folder callled ide3, with nothing visible in it.

EDIT: Just connected drives with a USB to sATA interface to a pc. the drives showed but with unknown filesystem (I think it should be ext2).
I attached a screenshot from the device manager showing the disks and it's partitions

After installing "Ext2 IFS for Windows" I could assign a drive letter but Windows doesn't recognise the file system. So I now also installed "Diskinternals - LinuxReader" and I can now browse two partitions. My data and a system partition (102MB) which I suspect is the boot drive. The last partition remains unaccessible.

So now that I now my data is in tact, what should I do next?

Hi,
sometimes the system partition is corrupted. Some lines in the log point to this, too.
Connect the disk to a linux system (or PC with a linux booted from CD) and run a diskcheck (e2fsck)

The third partition is a swap space if I remember correctly.

So I booted on linux and ran the tests on the system partition of both disks separately as i have only one sata available.
Some errors were found and repaired on the second disk.

I replaced them in my nas but still it doesn't boot. I will check again with the serial adapter.

Hi,
there is a problem with the raid array.
On nas-portal.org there are some guides how to restore a broken raid array.
All the procedure is done from the system console.

The nas seems to boot and should be accessible through the web interface.
Login with root on the console and check which IP address the nas is using with "ifconfig".

Thanks, for the info, unfortunately he only get's a loopback IP: 127.0.0.1
I cannot go to that subnet, can I?

could you point me to a good guide on how to rebuild the raid? As the forum is in german And I have no idea on what to search for. I will manage to read a thread in german.

Thanks

Hi,
if you search for "rebuild raid" on nas-portal you will find some English threads like this one

Strange that your nas does not have a valid IP address.
If you unplug the disks - does the nas boot correctly and is accessible though the web gui?

From the command line you could configure an IP address by using the ifconfig command.
Then maybe the route to your gateway (router) is missing. Add this with "route add default gateway 192.168.2.1" or whatever the IP should be.

Indeed, when no disks are connected the nas boots up properly.

Unfortunately 1 disk started to smoke just now. Don't know why... Now I'm really stumped...

I don't think it's worth rebuilding the raid If I have only one disk left, is it? Is there a way to copy my data to another disk

If you don't have a backup it is high noon.

I would try to copy the data and then rebuild the system from scratch.

I acquired two new disks, I made a byte to byte copy of the old one which is still "working" so now I have a backup (I hope)

next I tried booting up the nas with only the other new disk. this works fine. I could format the disk to EXT3. using the webif. Then I attached the old disk to the nas again, but still it doesn't boot properly No valid Ip is issued and he detected some issues on the file system. after running another e2fsck and fixing a huge load of errors, the file system is clean.
When booting I still have the same results.

Is it safe to format the boot partition of the drive? If I do so will the nas be able to repair this section?

Thanks, once more...
I really hope this mess can be resolved, my wife will kill me if it wouldn't.
