Auto Import Volume not Working

[Bob Cooper]

Hi, I'm a bit of a noob with freenas but here goes:

I had an error with a mirrored zfs drive on one freenas server that was preventing the server from starting up so I removed the offending drives (2 x 4tb drives).

I'm now trying to auto import the failed drives into a new freenas server running 8.0.4 but I get the following error message:

Error: [MiddlewareError: The volume "Theatre1_4TB" failed to import, for further details check pool status]

So my question is, how do I check the pool status?

Thanks,

Bob

Go to the shell from the web GUI, or ssh into the server, and type "zpool status" (without the quotes). For good measure, do "zpool import" as well. Paste that output here.

 

[Bob Cooper]

I can't find a shell option in the web GUI (see screenshot) do i need to enable this option somehow?

 

[danb35]

Sorry, I missed in your OP that you're running an ancient version of FreeNAS. In that case, you'll have to ssh in. Make sure the ssh service is enabled.

 

[Bob Cooper]

Yeah, I really need to upgrade it but don't feel confident enough to try that yet! I've enabled ssh in the services section, does this mean I can enter commands from the terminal on my mac or do I need to configure things more?

Sorry if these are basic questions, I really want to learn freenas more but am finding the learning curve rather steep!

Thanks,
Bob

So, with ssh enabled, and "allow password login" and "login as root with password" checked (use the wrench icon to the right of the switch for the ssh service), you'd then fire up the terminal on your mac and do

$ ssh root@ip.of.your.server
Enter your root password, and you'll be logged in to the freenas server. Then you can run the zpool status and zpool import commands and see where you are.

Great, thanks for that. So here is the results:

The one I'm trying to import is Theatre1_4TB

Thanks,

OK, it looks like the pool wasn't properly exported from the last system you used it on (see http://illumos.org/msg/ZFS-8000-EY for the same error text the message is trying to direct you to). Was that also a FreeNAS 8.0.x system? If so, you should be fine to do

# zpool import -f Theatre1_4TB

If that succeeds without errors, then do

# zpool export Theatre1_4TB

and try the auto import again.

ETA: ZFS is really designed to work best with all your storage in a single pool, which you can then carve up into datasets as needed/desired. In this way, you can allocate storage dynamically, rather than being stuck with the disk size available in each volume. What you're doing isn't wrong as such, but it really isn't the way ZFS was designed to be used.

 

[Bob Cooper]

Yes, I had to remove it from the other system as it was stopping the server from starting up.
I tried # zpool import -f Theatre1_4TB
but get the following error:

cannot import 'Theatre1_4TB': no such pool available

Thanks,

Bob

 

[Bob Cooper]

Ah, I figured it out, thanks so much for your help, knowing how to run commands feels like a big step to understanding freenas better.

How were you able to get it working?

 

[mcolinp]

I as well am dealing with a similar situation. Did you get it working simply because you mistyped a command in earlier attempts; or did you do something else entirely?
