RND2000 flashing
Hi,
I've got an old readynas which I have been happy with. 2 days ago I had a powercut.
Now the NAS will not boot, it just flashes / blinks. Theres LEDs = blue Power, yellow ACT, green disk 1 and 2.
All of them blink 3 times quickly, then disk 1 blinks 3 times more slowly.
I removed disk 1 and now the disk 1 light blinks 5 times instead of 3.
I found this
<<https://community.netgear.com/t5/Using-your-ReadyNAS/ReadyNAS-LED-patterns/td-p/543982
LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by an 1s delay, followed by a number of slow blinks. The number of slow blinks will be the error code.
Current error codes:
1 - Vendor mismatch
2 - No disks detected
3 - Bad contents on root partition of disks
4 - Flash error
5 - Unsupported RAID configuration >>
So 5 times instead (after removing disk 1) makes sense as it cannot raid just 1 disk.
My Q is should I just replace disk 1, I'm a little worried by the use of the word (for #3) "disks" i.e both. Or because light 1 flashed can i assume disk 1 is the problem.?
Thank you in advance :-)
Marc_V is correct, the duo can boot with only disk 2 installed.
If you are lucky, only the OS partition on disk 1 is damaged, and the data is ok. I suggest connecting disk 1 to a Windows PC (using USB or SATA), and then see if R-linux for Windows can access the data. https://www.r-studio.com/free-linux-recovery/ Note that will only work with XRAID. If you are using RAID-0, you'd need the full R-Studio package. You can download the full version for free, but you'd need to purchase before you can extract any data.
I also suggest testing them in a Windows PC with vendor tools (Seatools for Seagate, Lifeguard for Western Digital).
Power down the NAS before you remove the disks, and label them by slot as you remove them. Don't format them when you connect them to the PC, as that will destroy any data. Windows won't recognize the file system, but the tools listed above will detect healthy disks, and can access them directly.

Hi pgtips
Have you checked RAIDar on the status of your NAS?
What RAID configuration is on your NAS? If it's RAID 1 it should still boot up fine. If it's RAID 0 however it might not get the NAS recover since it does not have any protection for failure.
You can install RAIDar and check what is the status of the NAS once detected. With the 3 slow blinks you mentioned seems to me that you are having a full OS/Data volume or corrupt root. Try to check on the logs as well and get diagnostics.log.
Regards
Hi,
sorry forgot to mention that Raidar doesn't see the NAS. I've only got the blinking lights to work from
