ReadyNAS 316 (6x4TB Enterprise) - No volumes after graceful shutdown and restart

Ran mdadm --examine on sdb3 and sda3 but did not see any event counters.

/dev/sda3
Events: 16711
/dev/sdb3:
Events: 16711
/dev/sdf3:
Events: 16702

This is a bit odd, since last time mdadm told you sdf3 wasn't in an array.

A bit more odd is that disk 2 appears to be in sync (the event counter matches sda3)..

I think the next step is to power down, remove sdf, and power up normally, and see what happens.  If the volume does mount, then back up the data before doing anything else.

No luck. Can't access old Windows Shares. WebUI shows all 5 drives healthy but "no volumes exist". I uploaded a screen shot of WebUI status.

Can you get a second set of logs with the NAS in this state?

Hello RT6507 

Please see the volume logs once and please find whether the md127 is mounted. 

If md127 is not mounted then please mount the volume using the below command 

df -h 

cat/ proc/partitions

mdadm -A --scan

We offer paid data recovery service.

Note: Data recovery is to investigate whether the data can be recovered. We do not promise to recover the data. Data recovery is paid to check and investigate.

I don't see a mention of md127 in the Volume.log. Would I issue the mdadm mount commands from Tech Support mode as Telnet session seems refused with NAS_IV in standard bootup?

OK. ran df -h and others from Telnet - Tech Support mode.

error on 2nd cmd: "-sh: cat/: not found"

mdadm: "/dev/md/data-0 assembled from 4 drives and 1 spare - not  enough to start the array."

What are the terms for data recovery from you?

Also, tried these commands with all six drives installed and got slightly different messages. See uploaded screen shot.

Hi StephenB.

I wonder if you saw my last logs and screen shots uploaded to Box? Do you see any hope to continue trying to restore my RN316 to normal operations or should I shift to a data recovery focus. Either way, Thank You for your insight and patience in trying to help me resolve this problem. Your instructions have been clear and concise. I'm grateful for your help. If its time to admit defeat I'll know we tried our best.

Can you provide more information on Netgear data recovery service, such as costs and what you would need to access my NAS? Thanks.

Hello RT6507 ,

The basic pay for data recovery service would cost around 200 USD. And we would need SDM to do the data recovery process.

OK. What is "SDM"?

Secure Diagnostic Mode.

Go to the settings page in the web admin interface and look at the support section.

I'm assuming SDM is through remote access, right? How do we get this recovery process started?

Yes, when you enable it, Netgear can access the NAS remotely.

You need a contract for it.  AnishaA should be able to help facilitate that.

Hello RT6507 ,

Please open a new support case ticket. We will provide you with the encryption link for purchasing the contract.
