ReadyNAS Pro 516 No Volume Exists
Hi, Hope someone out there can help. Its been awhile since I needed community support for my unit. When I recently realized the unit could not be accessed, i soft reset and the interface shows "No...
First off, do you have a 516 (native OS6 unit) or Ultra6 (originally ran OS4.2.x, but you may have updated to OS6, so let us know which it is)? Your messages states both.
What does RAIDar show? Do you see any progress messages before you get to "no volumes"?
- Hi Sandshark,
Thanks for checking in. Sorry about the confusion, it is a 516, native OS6. I originally had an Ultra6 that was replaced by the manufacturer with the newer version.
I did originally see a message in RAIDar about needing to remove Disks #1,2,3 (all my disks, 2x4TB, 1x2TB if I remember correctly, WD40EFRX) but it no longer appears. It asked to update firmware for a hotfix, which I did, but it couldn't communicate with the hardware and still asks.to.uodaye to 6.10.6. It seems the message may have disappeared since.Hi Sandshark,
Now I'm able to see that messaage again, "Remove Inactive Volumes to use the disk. #1,2,3".
The volumes show 0 space, yet also no shares, etc. I'm at a complete loss. Tempted to remove and all three drives and try to re-index? But I wont do anything without advice from you experts out there. Hoping to recover all that data. I do have a backup USB-connected drive, but only a portion of my data is there.
DO NOT remove or insert the drives with power on or make any other attempt to re-sync without specific instructions. It can only make matters worse.
Your volume most likely has BTRFS errors that the system cannot resolve. That sometimes "just happens", and sometimes is due to one or more drives being faulty. Before going any further, it's best to test the drives. The best way to do that is to use a PC and WD Lifeguard (assuming all WD drives), connecting each drive to the PC internally or via a USB dock. The NAS Built-in drive test from the boot menu isn't as thorough, but doesn't require extra hardware.
Once you find out the health of the drives, you may be able to boot with just two drives and it'll be fine, though the volume will be "degraded" (not redundent). If not, StephenB can help you try to recover at least the rest of the data if you are comfortable using SSH and the Linux command line. If you are not, then Netgear support is your best solution.
