The volume (ZFS) state is UNKNOWN:

[daniel.leao77]

Hello everyone,

I have the following error "The volume [pool] (ZFS) state is UNKNOWN:" I did some processes that I saw here in the forum, but with no success.

I'm trying to access my volume named "BKP"

Sys.
FreeNAS-9.10.2-U3 (e1497f269)
Intel(R) Xeon(R) CPU E5335 @ 2.00GHz
(4) HD Seagate 2TB RAID 0


zpool status -v only returns the USB and Freenas-boot.


[root@freenas] ~# zpool status -v
pool: freenas-boot
state: ONLINE
scan: scrub repaired 0 in 0h1m with 0 errors on Fri Oct 13 03:46:08 2017
config:

NAME STATE READ WRITE CKSUM
freenas-boot ONLINE 0 0 0
da0p2 ONLINE 0 0 0

errors: No known data errors



zpool list -v returns the same result of zpool status -v


[root@freenas] ~# zpool list -v
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
freenas-boot 7.19G 647M 6.56G - - 8% 1.00x ONLINE -
da0p2 7.19G 647M 6.56G - - 8%



In the GUI, i see the disk, img below.

Anyone have any idea how i recovery this volume?
Thanks in advance for help

It looks like you used a RAID controller, which is a big no-no when using FreeNAS as ZFS is unable to manage the disks.

Your chances of recovery are slim to none.

As @m0nkey_ said, if you built a ZFS pool on a hardware RAID set, you're likely SOL. But what do you see if you run zpool import?

When i run zpool import, nothing happens.

Code:

[root@freenas] ~# zpool import
[root@freenas] ~#

I do not know if it helps, but when I go to "Storage> volume", I can see the volume, follow img, and I only see the link to "Detach Volume"

So the pool isn't online, and it isn't available to import. That's a bad sign. In fact, it's a very bad sign. Did you set up the pool on a hardware RAID set?

Yes

Is that hardware RAID set showing any errors? If so, see if you can correct them.

When i go on "Storage>Volumes>Volume Manager" i can see the partition "mfid0"

I'll see then.

So it sees that the device is there, but doesn't seem to see that it has a valid partition table. This is why we don't recommend using hardware RAID with FreeNAS (or with ZFS at all, really). If you can't fix the hardware RAID using the RAID controller's tools, I think your data is gone.

I think i found my problem...

:(:(

It appears you're not going to recover from that. I would take this as a lesson learned.

ZFS needs direct access to the drives for this very reason. ZFS and SMART could have warned you about a potential failure.

 

[danb35]

Yeah, unless you can resurrect those two disks, that's going to be fatal.

Why would you make a storage pool as RAID-0. That gives you no redundancy. You didn't look at any of the hardware guides or ask any questions before you just slapped some junk together and called it good.
