RN2120v2 firmware upgrade failure - admin panel offline

Hello,

 

We have a RN2120v2 with 4 x 3Tb disks, purchased diskless. The firmware was updated from 6.2.4 to 6.5.2 via the admin panel and then onto 6.7.4. Rebooted it as usual and thought all would be fine but on reboot the ReadyNAS Admin panel is offline and I'm unable to access the shares via SMB.

 

Having downloaded the logs via RAIDer, I can see the following:

 

[2017/06/05 10:38:38] Updated from ReadyNASOS 6.2.4 (ReadyNASOS) to 6.5.2 (ReadyNASOS).
[2017/06/05 16:57:43 UTC] Updated from ReadyNASOS 6.5.2 (ReadyNASOS) to 6.7.4 (ReadyNASOS).

I've done an OS reinstall via the boot menu a number of times and also reloaded the same fimware from a local image using the https://x.x.x.x/fwbroker process but that doesn't do anything.

 

Unfortunately I really need to access a couple of the shares on the device as recent backups don't exist (that's another discussion....)

 

I've tried to get in via SSH and FTP I'm unable to do so....I can supply the full logs if required - I'd rather not have to do a full factory reset at this time if I can help it.

 

Thanks.

    Hi,

    Seems that the UI is down due to sql databases. Not 100% sure, but you should still be able to access the data unless there is something else wrong. When you updated; 6.2.4 --> 6.5.2 --> 6.7.4 did you do that all in one go?

    If so, that could be the problem and then the issue is likely that the NAS filesystem is working hard right now to accomodate changes in newer FWs.

    Can you post the log: btrfs.log please?


    Thanks

      Hello,

      Thanks for your reply - yes I did see that although wasn't sure why or how this would be the case, unless the internal database ended up corrupt during the firmware upgrade. The upgrade was done in one go (the GUI simply offered an upgrade to 6.7.4 so this was done) - at the time we didn't know about the requirement to step up to 6.5.* before going to 6.7.4 but given the admin panel offered it, the update was done.

       

      The NAS has been left on for several days at a time with no change - right now for instance there's no disk activity on any of the four disks.

       

      The btfrs.log contains:

        Okay, so the filesystem stats are fine really. Not too much metadata for the amount of data and the volume is fairly balanced. There is of course a good amount of snapshots, but nothing outrages. So perhaps that is not the problem.

        It is hard to know exactly what the cause is, without looking at the unit. I reckon you would need to open a ticket with support. I think that is the best cause of action when you have no access (and can't make any changes, etc). They should be able to diagnose it for you.
