ZFS pool corruption issues after Freenas upgrade

[patrick0525]

From my PC, I cannot got to /mnt/Data? The pool name is Data and it is RAID-5 What steps do I need to take?

 

[patrick0525]

I tried zpool status -x and it says "all pools are healthy"
I tried zpool import -fFX and displays the same results as command line: zpool import

I tried zpool import -fFX Data .....something happened. Nothing came back
When I tried zpool import ....... ZERO corrupted meta messages appeared.

What just happened?
It probably has something to do with zpool upgrade. My pool: Data goes back many years ago and I do recall doing a some type of ZFS upgrade but it was never effected by a Freenas upgrade.

After you did the 'zpool import -fFX Data', what does 'zpool status' return?

Oh, and your pool isn't RAID5. It's RAIDZ1. Those aren't the same thing.

 

[patrick0525]

zpool status reported a healthy status. I was able to cd to Data and saw all files.
Do I need to do a xpool upgrade and how?

 

[danb35]

The output of zpool status should have told you if you need to do a pool upgrade.

 

[patrick0525]

It did mention I was using legacy zpool. How do I do an zpool upgrade?

In your screenshot of your output of zpool status, it shows your drives
as aacd

Are your disks connected to a Adaptec AdvancedRAID Controller Device,
is this right?

I'm afraid this is not gonna turn out well.

@cyberjock
HELP!
@patrick0525 do nothing until someone (guru) weighs in here...

 

[cyberjock]

This looks unrecoverable. Can you attach a debug file?

I was able to recover. I saw my files using winscp from the pc to the nas.I used zpo ol import -fFx Data and zpool status reported heslthy. Yes it is an Adaptec/Dell raid card.

If you don't have a backup of your data, get er done!
RAID cards ARE BAD!!!!
I strongly urge you to get rid of that Adaptec RAID card and purchase an LSI HBA or an LSI RAID
card that can be flashed to HBA mode. FreeNAS needs DIRECT ACCESS to the drives in your volume.
You have dodged a bullet. We are happy you were able
to recover this time, but know that next time you may not.

Which LSI do u recommend? What actually happened to cause that meta data fault?

Which LSI do u recommend?

The IBM M1015 (flashed to IT mode) is a favorite around here, but I suggest spending some time digesting the various hardware recommendation threads.

What actually happened to cause that meta data fault?

No way to tell from the information provided, but the key fact is that ZFS expects direct access to and full control of all pool drives, and not providing that often leads to problems.

+1

The card Robert suggests is the same one I use and is available at a pretty low cost

 

[patrick0525]

Thanks I will change raid cards soon.

 

[Robert Trevellyan]

The assumption here is that you don't have enough SATA ports on your motherboard, or that they are somehow unsuitable. If that assumption is invalid, just ditch the RAID card and go direct.

 

[patrick0525]

Yes, I don't have enough sata ports on the MOBO. Any deals on the IBM M1015 card out-there ? E-bay has them for $80-$100.

 

[danb35]

What is your hardware that doesn't have at least 5 SATA ports? That's about the right price range for a M1015.
