FreeNAS 8 & RAID 0 failed

[phuocnguyen1891994]

System:
FreeNAS-8.2.0
Running on VirtualBox
stripe with 10 virtual disk
Yesterday, due to power lost, I was unable to access my data on the pool.
Here the result of <zpool status>

Code:

	   corruption.  Applications may be affected.

errors: 1 data errors, use '-v' for a list	 

Tried to mount the pool as readonly but no luck.
Any help on how to get the data from the pool would be appreciated.

Update:
Since this is virtual machine I was clone the drive to other place and start troubleshooting
I've installed FreeNAS 11.2 and try to get my pool online but it seem worse
After a scrub I get 2 more drive degraded => 4 drive has degraded

Code:

[root@freenas ~]# zpool status PHUCHAO

FreeNAS-8.2.0

Wow thats old!

Running on VirtualBox

Only advisable for testing and learning FreeNAS as FreeNAS and ZFS should have direct access to the hard drives for any kind of reliabel fault detection.

stripe with 10 virtual disk

If any disk has any issues that data is gone. If a disk fails, ALL data is gone. ZFS in a pure stripe can only detect errors. It cannot correct them.

I was clone the drive

Drive or drives? your zpool shows 10 drives.

Looks like your data is gone.

 

[Ericloewe]

Yeah, next time make sure your pool has some sort of redundancy and doesn't consist of 10 (!) single-disk vdevs.

It's pretty miraculous that you got this far, really.

 

[phuocnguyen1891994]

Yah, that my bad to keep them till now without any redundancy.
Is there any possible to recover the data or any recommend on data recovery center can help me with this?

I've cloned all drive

 

[kdragon75]

You would have to send the failed drive to a data recovery center and have them clone it to a new drive. This will still likely result on most/all data being lost.
