readynas 516 decided it doesnt exist after adding 2 new WD Red 10tb drives
OK, This is going to be a long one, as I did plenty of things wrong in retrospect, and now I dont want to make any more mistakes going forward in case I can fix this. I will state up front, my main ...
Resync is quite drive intensive, so a second drive failing during one is not a coincidence, it's a real potential hazard. While one does not expect that on a two year old drive, it is always best to update your backup before doing an expansion or drive replacement. If the data was still accessable when the first replacement completed sync, you lost yet another opportunity to try and backup your data. But I suspect there was already something amiss, which is why the second sync didn't complete.
You cannot put the old drives back in, they are now out of sync with the volume.
Regarding the larger drive, you are thinking of the old RAIDiator 4.2.x expansion restrictions. OS6 has none that are likely to be reached in the lifetime of your NAS.
Let one of the moderators analyze your logs and see if there is any hope of recovery.
Good Stuff. I will try to grab the logs.
Hi Pairofdocs,
I checked the logs. The volume went offline because there is not enough operational disk in the raid array.

Jul 22 21:59:00 chonk kernel: md/raid:md126: not enough operational devices (2/6 failed)Can you enable the Secure Diagnostic Mode (SDM) on the NAS? We can look a little closer at the issue to see what else is possible. You can enable SDM by going to System > Settings > Support. You may send to me the 5-digit code via PM after enabling it.
Hi Pairofdocs,
It looks like the problem with the unit is that the OS is full. We cannot remount the OS from Normal mode. Can we reboot the NAS in Tech Support mode for the meantime? You do not have to be physically near the device. We can boot the NAS in TS mode on our end.
Regards,
Yes. Please do what you need...even if you lose data, itsmbetter than my current situation.
Best,
Aron
