HELP, All of a sudden my drive pools are offline?! I can't reach them, however nothing has changed on our end.

Neither Disk Drill nor EaseUS supports ZFS, sorry.

What Types of Drives or Disks Can I Recover Files From?

No matter what type of storage device you’ve lost data from, if you can normally connect it to your Mac and view the contents, Disk Drill can scan it. Even if you’re currently having trouble accessing your hard drive or […]

Supported file systems - EaseUS Partition Master

EaseUS Partition Master could support the following file systems: FAT12, FAT16, FAT32, NTFS and EXT2/EXT3/EXT4.

Hm, okay yes found that as well. It was to see that clearly last night.

 

[Woozy Face]

I found something else which is much cheaper only 99 euro than that klennet which is 399 euro tool and best of all it can run on Linux. Maybe you should partner up with these guys to make an app for true nas? So we can do recoveries from within the admin panel perhaps?!

It may be able to handle single ZFS partitions, but I don't think it can handle ZFS pools spread over multiple disks. Look, I think you should go with what's known to work. If you use a different tool, you may further damage your pool, and make recovery impossible.

Well done Samuel, time and time again I see you offer support and offer help to others without any hesitation.

@Someoneusin... So in summary, let me get this right:
Moving to a new platform for a business/production environment with no rollback plan.
Criticise the very software providing your business revenue
Not having a service agreement (considering you've posted in the community forums for assistance)
And then to shy away from the software that might get you out of this situation of losing 17 years? of data over a few hundred dollars...

<forum-respect>I'll not comment on the above but I sure hope you can tell what I'm thinking <forum-respect/>

Thank you Samuel, you deserve another well earned pat on the back.

A few hundred bucks is too much...

Is there anyone whom knows a freeware recovery tool? I just hate spending money especially that much on a tool which I going to use once and never again.....

Also I'm recovering from a bankruptcy then also it's the true NAS software which killed a completely new drive, so if you are not helping with this topic please move on with your life and don't interrupt me, if you don't know any background story OK?

 

[Woozy Face]

But do you have any cheaper alternatives? I don't mind if you tested them or not at this point I'm willing to try everything i can. But as i said before i was bankrupt so 399 Eur or dollar or what ever currency is just way too much at this point. :'(

@tangles believe me if i wasn't in this recovery mode with my company and myself I would have said the same but meh no can do! Sorry again for my harsh responses but I'm not the type of guy which keep things nice when my feelings are ducked. I'm just straight and clear about that. no hard feelings against you but I just feel like anger and everything negative at this point.

 

[Samuel Tai]

This is extremely unlikely. What the SMART results show is a bunch of damaged sectors that can't be relocated, which seems indicative of a head crash physically damaging a large patch of sectors on a platter surface.

Also, your description of the failure mode has changed along the way. You initially claimed there were no configuration changes, but then admitted to adding a new drive to expand your pool, which you unwisely did by striping data over both disks without redundancy. You still haven't provided details of your hardware nor your pool disks, so I'm working with incomplete and sometimes contradictory information on your part.

While I'm sympathetic towards your plight and your budgetary situation, consider that the alternative is a professional data recovery service, with costs in the tens of thousands of Euros. I still recommend Klennet, which is known to work and has been designed for your circumstance, over another tool which may or may not work.

Hmm then it must be, a factory failure maybe

yes I did not make any changes except for the initial setup of course. I did not do any scaling or anything after the initial setup that's what I mean. The details are in the image I've added this morning,

I know about that, thanks for your sympathy, i'ts not that I do not acknowledge that. It's just the fact that I cannot afford any extra costs at this point. Of course 399 is nothing compared to other solutions but at this point it's just too much to afford.

This might be a cheaper option at ~$150:

Effortless data recovery from complex RAID

UFS Explorer RAID Recovery is special software aimed at dealing with RAID-specific data recovery tasks of various complexity, along with stand-alone storages

www.ufsexplorer.com

This was mentioned in the Klennet successful recovery thread I mentioned earlier, but had mixed results. For a simple 2-way stripe pool like yours, it may have better success.

That's more like it! It is running a lost data scan right now! I post back the results later, for now I also ordered 2 new 2 TB drives, which should arrive tomorrow. So I can do a mirror setup to never have this kind of issue again.

 

[Woozy Face]

Hmm, there is good news and bad news.

The good news I've got most of my files back, the bad news is every file is now random number dot file extension. So that's not useful. If anybody knows how to get the right names back please inform me.

Meanwhile, I found the external drive which I used to move the files from my old storage to True NAS. Although I formatted that one again I can check if ease us is able to find that data back in the correct sense…

So still a lot to do but at least one step further for now, thanks again!

There might still be hope, OK hear me out… It seems that there were 0 bytes saved on the dead drive. I had indeed a drive which did the reset to track zero over and over it occurred not right away though. So I did a filthy trick, by hitting the drive on it's left side so from my point of view right… DON'T TRY THIS AT HOME! But meh it worked just enough to show me that no files were actually stored on there.

But hurray right. And I can confirm that the data is actually stored on the GOOD drive.

Now can I use the magic of 'scale' to scale or just kick the dead drive out of the pool? Making the pool contain only the good drive?

Also, no luck here although ease us give me the file structure of the files. Then are not the right ones! SWIM must have reused the drive for another project.

@Samuel-tai.101891 could you plz answer this?

 

[Samuel Tai]

Sorry for the delay. There was a storm that blew through and knocked out my power for 5 hours. Even cellular service was down, so I had no connectivity.

Since your pool is a stripe pool, it's not possible to go from a 2-way stripe to a 1-way stripe and keep your data. (This IS possible with a 2-way mirror pool.)

I'm sorry, I don't have any other suggestions than trying Klennet.

Oh, hope you are fine?! Better the wind than dhat knock's the power down!

Aaah sigh, oh also… Ease US had no issues reading the drive as well but same issue. It just seems that the name data is gone of all files well let's put the drive in storage for now and let's try to save some money! :(
