Rebooting to 11.2-us lost pool

[StephenRadford]

HI need some help here, not sure what is going on. I rebooted after an update to 11.2-US and found I had lost a pool, one that uses a plug in raid card has the lost "DiamondDataStore" of 5 x 3Tb disks, the other pool "Backup" is of 5 x 2Tb disks off the motherboard is OK.
When I tried to re-import the missing "DiamondDataStore" I have this popup in a window.
Is this a python problem and I have to reinstall Freenas?
Any help gratefully received.

Stephen

uses a plug in raid card

That sounds really bad.

What's the output of zpool import?

Full hardware specs will also help. Read the forum rules before posting again.

HI guys, I left the machine off over night, started up, no pool "DiamondDataStore" showing, it allowed me to import "DiamondDataStore" pool using the "add" button, I imported "DiamondDataStore | 17774638431354291343", I had "Confirm these settings". I then had the pool shown as "unknown"
The result of "zpool import" is shown in the screenshot.
It is there and online, not sure why I can not see it.
Thanks
Stephen

Try to connect this pool via sata cable to mobo.

 

[Redcoat]

I recommend @tfran1990 suggestion - disconnect the 5 drives currently connected to the motherboard and connect the 5 drives currently on the raid controller in their place.

Aren't their similarities here to the problem you had back in May this year? The one of this thread https://www.ixsystems.com/community/threads/degraded-drive-unable-to-see-data.76699/#post-533645

what did you do to solve this problem the first time?
With that raid card you might continue to have problems.
If you by pass the raid card buy connecting the pool directly to the mobo, i would get a correct HBA

 

[StephenRadford]

Just a quick follow up did you look at the screen shot? It shows the disks and pool are online, but not visible.

 

[Redcoat]

What happens if you use the command "zpool import DiamondDataStore" (without quotes)? Or "zpool import 17774638431354291343" (I did not check that id number, just copied from your post above...)

just tried "zpool import -F DiamondDataStore", it is showing
"cannot mount 'DiamondDataStore/Downloads': Input/output error"
"cannot mount 'DiamondDataStore/Stephens_Images': Unknown error:122"
These are both windows share directories.
This was done as @tfran1990 suggested by swapping over the cable to the motherboard.

 

[Redcoat]

Are any other shares in that pool mounted?

What's the output of zpool status?

 

[StephenRadford]

Really really struggled with this, sorry for the delay in replying. I cut my losses in the end and deleted the pool.
I reinstalled all the datasets and transfered the data back from "the backups".
It looks like a drive was falling but no warning messages. I am in the process of replacing the drive.
I have taken the drive off line to be replaced and a resilvering process has automaticaly started.
Question, do I wait untill resilvering has finished to switch the machine off, as rebooting is the only way I can set the pass through on the raid card so FreeNAS can see the new install drive.

 

[pschatz100]

Has the Areca ARC 1260 256Mb 16 port PCIe raid controller been flashed to an IT or pass-through mode? It does not appear to be the case. If not, I would imagine that ZFS cannot see the individual disks, therefore it cannot manage them. Using hardware RAID is a no-no. There are lots of threads and comments about this.

UPDATE -
Because of viewing the server using a web browser I never got to see the server start up sequence. I started the boot sequence using a conected monitor to the server, I found that one of the memory sticks was showing a fault. Removed the stick restarted and so far no faults.
Thanks to everyone for the ideas.
