URGENT: (RN10200) Reboot of ReadyNas and have lost volume! #27933831
Hi,
Today I had an issue accessing my ReadyNas admin page and needed to reboot. Since reboot my volume is not accessible! I have lost everything and am hoping I can recover in some way.

Hi,
Yes I had to open a suppprt case, paid £99.00 for 3 years extended support which I think is a fair price given the situation I am in. For the purposes of this post so others can see what the likely resolution is....
I was unable to down my logs as device just gave an error when doing so, either from the admin page or from RAIDar application. The first line support person was very helpful in helping me provide relevant information and screenshot of the logs, uploading to support page. It transpires that my issue is caused by having almost no free available diskspace on the volume. This significantly degrades the performance of the ReadyNas running at this tollerance and as a result the volume is unmountable. (My data is still there but unable to mount volume due to 100% volume usage).
Next steps has been for me to put the device into Tech Support mode, provide a port number for them to access drive and remove files on my approval in order to get this below the 80% threshold. Following that I should be able to boot the device back as normal and manage my data from there on in.
I was not aware of this constraint on data Vs performance and potentially loosing access to the volume. I probably should have been! So to anyone else that has a panic as I did I hope the above helps you.
Interestingly though I can still SSH into my device, so wonder if I via command line locate the data and manage myself at this low level. Either way I have paid for support now so will let the experts work their magic.

You have 100% root volume usage not data volume usage. The root volume is the 4GB volume that holds the OS, config, logs etc.
To maintain optimum performance it's best not too fill your data volume too full, but on recent firmware high volume usages are handled better than they used to be. Having said that I'd still recommend keeping your volume usage down to 80-85% if at all possible.
Oh I see! 100% root volume usage. How did I manage that?
Can I ask how to questions via my support contract to ensure I don't do this again
Actually this does change my thoughts, as I now need to understand how the root volume got to 100%. Is this a case that the log files need to be deleted in order to free up space?
I was under the impression that this was down to my data volume not root volume. Given I do not activley add data to this volume, how can I stop this from happening in the future?
Thanks

Hi scar1,
Normally its the installed apps that fill-up the root; or at least as far as I have seen. So the best thing to watch out for is the path, make sure its pointed to the data volume so that all of the files that it will download will go to the data rather than the root volume.
Regards,
Recieved this update today from 3rd line.
"I have read your case and understand that you are experiencing some problems with retrieving data/files from hard drive that has been inserted to ReadyNAS device. I apologize for the inconvenience you have experienced.
Data recovery is beyond our scope of technical support since you will be dealing with the settings of the hard drive and not the NAS.
NETGEAR provides Data Recovery Services on a best effort basis using tools, technical knowledge and resources available within NETGEAR. NETGEAR does not guarantee that the data recovery can be accomplished successfully in every instance. The fee for initial diagnostics is NOT refundable."I am challenging this diagnosis as the reason I took extended support was to resolve this issue.
