Corrupt Boot - "Err: Could not mount root RAID d"
Hello,
My storage equipment NETGEAR Model No. RND4A Model name: ENDU40000
The machines has 3 discks – the first two have each 2GB and the third one 1.5GB – which is not used 2GB disk: SEGATE)
I already used the system for about 3 years with all my data on the disk.
Problem statement
Yesterdayn, I updated the last Firmware through Raidar – admin page.
Afterwards, the machine takes a very long time for booting and finally failed to boot.
According to the following instruction (http://kb.netgear.com/app/answers/detail/a_id/24874/~/how-do-i-access-the-boot-menu-on-my-readynas-duo-%2F-nv-%2F-nv%2B-%2F-x6%2F600%3F), I made a OS reinstall.
The machine likely updated again the FW software, checked the disk and the file system and booted.
One of the disks (channel 1) has an ATA error and disappeared from the Raidar.
It seems all volume/passwords were lost.
I restarted the machine • It takes one night to reboot (also with check filesystem) – but failed again.
On thescreen of the ReadyNas, it shows "Err: Could not mount root RAID d"
On the Taidar screeen, it indicates "Corrupt Boot"
Could you plase help me? All my data is on the disck :(
Thanks in advance
John

That model number is probably RND4000? Can you read this and tell us what model you have:

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.
Many thanks for your prompt reply.
I suppose the updated FW was raidiator-x86 version 4.2.27
I did not do FW update for years, I don't remember the last version on my sustem.
I do not have a back-up out of the Readynas. I suppose there is copy in the system of the sotrage?
After several tentaives, now the boot started. In Raidar, I see disk one is "health". I can browser it and see all my folders, but I can not access to them. When I want to connect to them through windows explore, it aks the use namer and password, but I can no longer use the old ones.
The Admin pagfe is empty - I can login, but see nothing.The second disk is showed as "died" in Raidar with a red X on it.
I am not an expert for the Ready system - and I am worry about my data on the disk.
Do you have a solution for this?
Please give me the instruction to remotly connect to my computer and payment to Readynas for this extra service is ok.
Many thanks
John
Hello Johnhyzhang,
I checked your profile and found that you have opened a ticket with the support center.
Your case is possible for L3 escalation. However, support contract is needed as the support warranty of your unit already expired.
As far as I can see, there is still hope retrieving your data. Please also try to access the admin page using a different web browser, in case you are able to, see permissions settings of the shares. See this article here for you to have idea how this is done.
Regards,
