Hi Everyone, a few days ago, I started having issues where I couldn't access my UNRAID server (1 parity, 2 data drives) through the web interface or the drives that had been mapped on my Windows 7 computer.  In my ignorance, I thought that the USB had been corrupted.  I proceeded to reformat it, and update it to 4.6, then 4.7 and then 5 beta.  I did this for several USB drives.  None of this helped me get access to the server.  It turns out it was the damn router that was defective. 

 

So now I'm on on UNRAID 4.7.  When I start up the server, it shows disk 1 as unformatted, and disk 2 appears to be OK (has all my previous files on it).  The parity drive shows as being "New".  So I figure all that messing around I did with the various UNRAID versions may have caused this.

 

I decide to copy my data from the UNRAID disk 2 to some other extra drives I have.  I first tried this with YAReG in Windows 7, however, it will only transfer a few hundred MB's of a 3 GB file and then stop.  Disk 1 (which appears unformatted in UNRAID) doesn't even show up in YAReg.

 

So I then decide to use Ubunutu 11.04 via USB stick in order connect my UNRAID drives and transfer the files off of them.  I'm able to mount Disk 2, but Ubuntu says I don't have permission to access the data.  Disk 1 doesn't even have the option to mount it in Ubuntu. 

 

Does anyone have any suggestions I can try?  Should I install and run Ubuntu from a "real hard drive" to get access?  Should I find a PC with Windows XP and use YAReG?  Or is there a way to remount the drives back into UNRAID 4.7?

 

 

I"ve attached my syslog.  Any help is much appreciated,

 

Thanks!

Well, your system is recognizing all the drives, so that's good. I'm a Linux guy, so my troubleshooting happens in Linux. There may be Windows equivalents to what I'm recommending, but I don't know them...

 

There may also be good steps to take within unRAID, so you should listen to others that have suggestions on that. I'm new to unRAID, but have been using Linux for a while.

 

From a command prompt on a Ubuntu live boot (the terminal is under Accessories in Ubuntu):

sudo fdisk -l

 

It looks like the disk that's getting recognized as having a valid reiser file system is sdc, but if you could paste the output for all the /dev/sdXX devices, that would be helpful. Based on what it shows for /dev/sdc, you'd want to try the following commands:

sudo mount /dev/sdc1 /mnt #it should be sdc1 - you can tell from the fdisk output. It should autodetect the filesystem type.

 

If that command succeeds, it won't give you any output. It may mount the device as root access only, which would explain you getting an access denied error when you try to copy files. Try running:

sudo nautilus &

 

That should launch a file explorer window as root, so you have access to copy files in that window.

Thanks for the advice Rustbucket.  I was about to try your tips, when I figured I'd give 4.6 one more shot.  Lo and behold, both disks recognized with proper content and were accessible!  Not so with 4.7 or 5.  Strange .

Not strange at all if they had an HPA at any time.  Might that be the case?  It is the reason some had issues upgrading.

 

If you have an extra moment or two, can you post the output of the following two commands on each of the disks:

 

cat /sys/block/sdX/size

 

dd status=noxfer count=1 if=/dev/sdX | od -Ad -t x1

 

(Where sdX = the correct device for each of your disks)

I'll post it when I get home tonight.  What's an HPA by the way?
