Unhandled Exception (yes another one)

[Simon Tiplady]

I know there are other threads about this, but...

I noticed the GUI was not loading, so I checked the error log, /var/log/nginx-error.log

Code:

errors: Permanent errors have been detected in the following files:

        //var/db/pkg/local.sqlite
        //var/db/pkg/repo-local.sqlite
        //usr/local/www/freenasUI/api/resources.py

the error in resources.py seems to concur with the nginx log.

the 2 sqlite files appear to be 0 bytes, is that normal?

The USB drive is only about 2 weeks old (as is the entire system, cables/motherboard/cpu/ram/drives/psu/drives) why would it fail so soon, would it be a software fault (file not being written properly after an upgrade) or a hardware failure? Should I send the drive back under warranty?

Your usb drive has failed, replace it with a better one and think about doing mirrored boot drives. Doing that will decrease the chances of seeing a failure because it will fix its self or just keep working. This isn't a software issue just that usb are cheap and not made very well.

 

[Simon Tiplady]

Surely a USB drive should last longer than 2 weeks? It's not a heavily used NAS system, mostly just used for backups, but I am going to start using i for media storage.

 

[SweetAndLow]

What type of USB? Some are better than others. If you want something good look at sata doms.

 

[Simon Tiplady]

I believe it was one of these: http://www.ebuyer.com/367886-verbatim-16gb-store-n-go-v3-usb-flash-drive-grey-49172
I've also got a spare (unused at the moment), if I used both and set it up as a mirrored boot, would that help?

SATA DOM looks like a good option, but I had hoped the USB drive would last far longer than it has done.

 

[SweetAndLow]

That USB drive doesn't look like a good one. Get a san disk cruzer fit, that will last you a couple years unless you just get a bad batch. I have had move for 2 years and it's going strong.

 

[Simon Tiplady]

This one? http://www.amazon.co.uk/gp/product/B00422DCB6

 

[Simon Tiplady]

If I reboot and choose one of the older boot environments, would that get me back into the system? And then I can download the config file? or would that also give me an old config? Should I just copy /data/freenas-v1.db , setup the new usb drive and then restore the config file to it?

 

[SweetAndLow]

That's not the one I told you but it should work. I said the fit is what people around here like. Make sure it's the USB 2.0 version.

You should backup your configuration using the gui and reinstall on a new usb. Then upload your configuration to the new install.

No reason to even mess with the old USB it's a crappy one.

 

[Simon Tiplady]

Any reason not to go with a USB3.0 upgrade on that device? http://www.amazon.co.uk/SanDisk-SDCZ43-016G-G46-Ultra-Flash-Drive/dp/B00LLEN5FQ/ref=dp_ob_title_ce

ok, did an upgrade on the old usb and it kept all configuration and got me working again. Couldn't access the web gui earlier. I've also used the 2nd spare drive I had so that they're mirrored. Will use this until the new ones arrive. Thanks for the product recommendation.

Thanks for listening to my advice and improving your setup. Now I just hope that USB does work for you so I don't look like an idiot.

:) I'd always meant to use 2nd device as a mirror, but never got around to doing it.

Will upgrade them for the new ones when they arrive.

For anyone else having trouble with boot devices, the option of upgrading over the top of the "broken" device could allow you short term access to the gui to download config for your new device.

Comparability issues

Fit arrived today, top of packet says "USB 2.0/3.0 Compatible" is that likely to be a problem? It was exactly the product you linked to on Amazon.

 

[SweetAndLow]

It will be fine, if it's the 2.0 version it won't need the usb3 drivers.
