Rebuilding lost file system

[accesser]

Hi all,

I've got myself into a bit of a dark corner with my NAS box. I have a Level 1 branded NS4000 I think this is basically the same as a Promise NS4300N just re branded.

I have a RAID 5 over 4 disks and everything was fine until it started to not post correctly I shot a few e-mails to Level1 support but just got very unhelpful responses. I started doing some reading and I found out how to telnet into the box hoping to find some more advanced management I poked around a few of the basic commands.

I ran a few of the test commands testing things like memory then I ran a test on the HDD's it appears this test has deleted the file system table as after this the box POST fine but all my data is gone the public directory that had all my data is gone and its back to its new status with folders I did not use and I had deleted are back.

If I'm right my data should still be on this disk over the raid 5 I just have to find a way to rebuild my file system.

Any ideas ?

What disk test did you run?

Its quite possible the RAID array was reset and rebuilt in which case there's little chance of recovery.

That's what I was thinking in the back of my mind but I hope its not the case.

pdtest : test all sata channel

Did the damage, The RAID array is still showing as intact so I'm hoping the array did not re build to a blank stage. The test did not take long to run that's what made me assume its just file table that got nuked but I could be wrong.
