I am new to unraid. Just bought the basic licence seeing that the trial did not allow for more than 3 drives.

I have x2 2TB (for data), x1 2TB (parity), x2 250gb (Cache). So that's, 4 drive all together.

 

All drives were working well until today. I left the parity to sync/ check to run last night then this morning, boom.

I am seeing a orange triangle next to 1 drive.

 

Using unassigned devices, I can mount and browser the drive using 'mc' via the console.

 

Please help. I'm losing my mind and all my videos :'(.

 

Attached is the Diagnostics log and screenshot of the main screen.

It's not clear what happened before this boot, but disk2 went out of sync at some point and when you hit "Check" it restart to rebuild it.

 

Let's wait it finish to see if your disk drive is ok.

So I screwed up. One of the data drives got corrupt.

 

Running Reclaim (window based software to recover drive with a XFS fs).

 

Can I format my parity drive or do I need to preclear? - I have precleared it before.

Whatever you do, do NOT hit format.

 

Please detailed the exact sequence of events and your exact steps.

I'm keeping my fingers crossed for you that you haven't gone beyond the point of no return.

Didn't hit format. But I did format the parity drive.

 

Funny thing, 1 data drive remained untouched, all data intact.

 

But the data drive in question has the same data as the above drive but scrambled.

While running data recovery, I see my old data. The data I'm looking for.

That's it. When you used ReclaiMe it wrote to the disk, and it went out of sync. The good news is that your disk will be restored to the previous (corrupt) state, so no data loss beyond that could be caused by the original corruption.

 

Let's wait until your disk is rebuilt to try recover using official XFS repair tools, ok?

Still running ReclaiMe, does it revert your hdd back to its previous state?

 

My cause for panic is that all my wedding and honeymoon pictures were on that drive.[emoji22]

I didn't used ReclaiMe yet, but XFS recoverability is high. Answering your question, none of the current recovery tools can restore the hdd to it's previous state, bit by bit, even if it recover all of your files. The recovery utility will always write some data on your disk, and this will bring the disk into a out-of-sync state at the end. There are two viable ways of recover files in unRAID:

 

1) using official xfs_repair tool: this will keep your parity protection valid, and can be triggered from the webui when the array is started in maintenance mode;

 

2) using any Windows recovery tools: this will invalidate your parity IF you run it as RW mode. Some tools access the disk as read-only, so no modifications are made to the disk. You'll have to copy the disk files to another disk, reinsert it into unRAID and then hit Format.

 

I suggest you try the first method before try the second one.

I gave up on ReclaiMe, I required a license.

 

I'll try your first option. What if I formatted the parity drive,  will it still work?

Again, it's advised to wait the disk rebuild first.

You can recover files even if your parity data is invalid, but you will be prone to hardware related data loss (disk failure).

You're probably going to hurt me for the stupid questions.

 

How would I recover the data drive using the nas?

 

This is what I done now:

Removed all drives from the Nas expect the faulty drive.

Probably you left your disk drive in an inconsistent state if you had stopped your data sync/rebuild operation. You have to let it rebuild prior to doing anything else.

 

Insert all disks first and then hit "Check". When it finishes, I'll help you try to fix the corruption, ok?

Any other way?

@Jarrodr: Have you formatted your Parity disk or have you not?

Do NOT hit format.

 

Also: you said you ran a parity "sync / check".

Did you run a check with the correcting box ticked or NOT ticked?

Did you run the parity check after or before the error?

Did you run parity sync or parity check?

Please be patient and not do anything drastic as you might worsen the situation.

 

@gfjardim: if the OP formatted the parity (he said so here), wouldn't restoring the failed disk basically overwriting it with gibberish?

I did format the parity. - I thought I would recovery the data drive and copy the contents to another drive (old parity)

 

I guess I have worsen the situation.

Stop the data rebuild right now. The first option is no longer an option in your case.

 

Remove the disk from unRAID, insert it on a Windows machine, install TeamViewer and send me your ID and Password by PM so I can assist you using a good recovery tool.

 

@gfjardim: if the OP formatted the parity (he said so here), wouldn't restoring the failed disk basically overwriting it with gibberish?

 

Probably just the beginning of the disk, since almost all filesystems stores their data on first/last blocks. Now it's not a corruption issue anymore, it's a overwrite one, and lot more difficult to handle.

Thank you sir. Charging the laptop now, lol.

A little late to this party, but thought I would just pile on with a few thoughts.

 

Anything you do outside of unRAID with any of your array disks including the parity disk is working against unRAIDs ability to save your data.

 

It's obviously too late now but you really should have asked before you did anything at all.

 

Also, an explanation of what the word format means. Format means "write an empty filesystem to this disk". That is what it has always meant on any computer you have ever used. Format is never a step in data recovery. And the unRAID parity drive doesn't even have a filesystem, so formatting it is completely pointless.

All of this is just for grins though, right?  I mean, certainly he has a full backup of his wedding and honey pictures, right??

Man, I hope so, or that gfjardim manages to recover them for him.....

Although, in the UK, I think the photographers keep a copy of them too, so it might not be as desperate a situation as it appears.  I feel for him, I do, I can't imagine telling my wife I'd lost our wedding photos.  Honeymoon photos might be an issue though.

 

When people have experienced data loss before, it maybe some media, music or whatever, but I'm crossing my fingers for the OP with this one. 

So you can see the spot I'm in.

 

I know gfjardim can work his magic. Once I get the data, I'm copying it on a separate hdd and keeping it away.
