Permission Issues: ReadyNAS RR4312X goes total read only mode, inoperable
We have two of these RR4312X (ReadyNAS 4312 with 10GBASE/T not showing up in the model list above). One is working fine still, the other one went totally read only all of a sudden. Please help! ...
It's because this extract is not enough. It only shows the allocated data blocks and the data inside it.
In btrfs.log from the log zip, also paste the section above this extract please.

Do you have snapshots enabled on the LUN? Bit rot protection? Compression? Metadata usage is indeed quite high.
Do you run balances? I was going to ask if you run any defrag, but if you use CoW LUNs, I'm not sure if defrag can help that much.
Is RAID10 an option?

Maybe he confuses Deskstar with Desktop... Because they're clearly NOT desktop drives, it takes about 6.5 seconds on Google to confirm that. First result = "Deskstar NAS Internal Drive Kit Data Sheet - HGST"
Though I give the thumbs up to HGST for finding possibly the most stupid name for a non-desktop drive.
