Hello,

I get a zpool I/O error on my RocketRaid volume which are 4 Samsung EcoGreen 1,5TB disks on my Highpoint RocketRAID 2310.

A while back i get the status:
One or more devices has experienced an error resulting in data corruption. Applications may be affected.
Click to expand...
A few hours later I get the message:
Unscheduled system reboot
Click to expand...
And now I have the Alert:
The volume RocketRaid state is UNKNOWN
Click to expand...

I have read some forum posts and tried to import the zpool but then I"ll get:
Code:
root@freenas:~ # zpool import RocketRaid
cannot import 'RocketRaid': I/O error
		Destroy and re-create the pool from
		a backup source.


So I'll hope I can get some help with this :(.

Here is some information:
Code:
root@freenas:~ # zpool status
  pool: ZFS_storage
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
		still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
		the pool may no longer be accessible by software that does not support
		the features. See zpool-features(7) for details.

What's puzzling me here is that you have a pool called ZFS_storage which seems to contain the 4 disks you're talking about.

Then there's the other pool that's having trouble... RocketRaid... which appears to be only a single disk.

Where is your real problem? with this single-disk volume or with the other pool using the 4 disks?

Or is it actually something entirely different and you have presented 4 other disks attached to the RocketRaid card as a single disk, using the RAID function of the card instead of FreeNAS to make a single volume? (this would be the 4.1TB da0 disk?)

My ZFS_storage is fine. I having trouble with my RocketRAID pool.
Which are 4 disks on a Highpoint RocketRAID controller. Freenas sees this as one disk.

You're not doing it right if FreeNAS can't see each of the disks individually... you will not get much support in this forum using hardware RAID with FreeNAS (but I'm sure you will get plenty of advice to not do that).

You will need to look at the options in the RAID BIOS to see what it's telling you about the RAID set.

If the one (RAID) disk presented to FreeNAS is dead, your pool might be toast.

You could try zpool status -v RocketRaid , which may be able to get the details of the missing/corrupt files.

You would possibly need to do as suggested by zpool import and import the volume using the ID:
zpool import 16390382078416128707

before the zpool status will get you something interesting.

You could also try zpool import with -f or -F options to force it to import...

Yeah, I know I was doing it wrong...

I have checked the raid config and everything looks fine to me. I think the problem is not the raid but it's freenas.

Thanks for the information. I'll try this later today.

Update:
I tried the following commands with Freenas 11.0 STABLE.

Code:
[root@freenas ~]# zpool status -v RocketRaid

[root@freenas ~]# zpool import 16390382078416128707

Still not working...

I booted Windows and checked the raid partition with different tools and everything looks fine.
My last options are trying a other motherboard and raid card.

Does anyone have any other suggestions?
Is there no way to see what the I/O error is?
