That model number is probably RND4000? Can you read this and tell us what model you have:
http://www.rnasguide.com/2012/01/09/how-to-tell-whether-i-have-a-duo-v1-or-duo-v2-or-nv-v1-or-nv-v2/
Do you know what firmware was on, and which you were upgrading to?
Was it an Xraid volume?
I take it there is no backup.
It it sounds like you might have a full OS partition. As you have no backup the way to sort this out would be for Netger support to remotely access your nas and clean up the OS partition.
If you had a backup ( which you should) then a factory default is another option - don't do this as the disks will be wiped)
By doing a firmware upgrade and OS reinstall you have probably created other problems, so fixing this locally by ssh is almost certainly not an option.
Netgear will charge you for a support event. There is a possibility that someone from the forums could help you, so I would suggest you wait a while. Don't do anything else to the nas or you will make the problem worse.

Hello again Johnhyzhang,
The case you have opened with the support center is for ReadyNASRNDU4000, please make sure of the model number.
Regards,

Yes it sounds like your OS partition is full, although there may also be some other issues related to your attempt to upgrade the firmware and the OS reinstall.
My suggestion to wait for a response from someone on the forum still stands. There may be someone who can help you directly. I would expect if you do get an offer that this happens usually quite quickly (1-2 days)
Edit: Reading through your second post again it seems that there are indeed some additional issues, so follow through with the support request that you have already made.
