ReadyNAS 102 – Blue light blinking, then no light
Hello, my ReadyNAS 102 stopped working recently, however I don't know when exactly. The behaviour now is that is when I power on the NAS, the blue power light starts blinking, afterwards a constant ...
Dear Stephen,
thanks for your reply on this matter.
I checked the following:
- The firmware that is installed on the netgear is 6.6.1
- The SMART status and the regular tests for the disks are ok/pass according to lifeguard
- I attached the disks (one at a time) to a linux machine with btrfs installed:
- The first disk showed the linux partitions and a large empty partition
- The second disk showed a large empty partition (although on osx this shows also the linux partitions)
- "btrfs filesystem show /dev/DEVICE" resulted in "no btrfs filesystem"
- I could not mount the device using the linux mount command
I did not yet try reinstalling the OS, but will do so later this week, if there is no way to view/access the data.
One more question: since the drives are in RAID, do they both have to be attached for me to be able mount them?
Hello smoens,
It is not a good sign that there is just large empty partition on both drives. There is a possibility we are looking at worst case that data is no longer there. Are the drives back on the NAS ? Can the raidar software utility detect the NAS on the network? If it does detect the NAS, there is a way to download the logs from raidar, please download the logs and kindly provide us a copy you through file sharing website like wikisend and just give us the download link.
As for the last question "since the drives are in RAID, do they both have to be attached for me to be able mount them?" This will depend what raid level the NAS was set to when it was initially setup.

Hi Marty,
that would be too bad.
The raidar software can see the drive for maybe a minute? Just when the drive is booting, I can also then ping the IP address that is reserved for the NAS. Do you think it will be possible to download the logs in this short amount of time? Or does it have to be booted "correctly"?
Aah, I am not sure anymore but I think I have used Raid 5 or 6. Looking at the wiki page, these require at least number of disks - 1 to operate. So in that sense i would be okay, since the RN102 is a 2 bay NAS?
Best,
Sandy
With an RN102, your options are XRAID (RAID-1), jbod and RAID-0.
With XRAID/RAID-1 you can boot with either disk. You can also boot with either disk if you had jbod/RAID-0 with two volumes.
If you had jbod/RAID-0 with only one volume then you'd need both disks to boot.
