Readynas 204 - v6.9.2 - Read only
It seems my RN204 decided to put shares into Ready Only mode. How do I find out why, and how do I fix it? Found this in dmesg.log: [Tue Feb 20 16:58:20 2018] BTRFS error (device md127): paren...

I've run a btrfs check --init-extent-tree on /dev/md127.
Why? If there is corruption that can bake it in.
Indeed...I got lucky it didn't do much.
Any thoughts on next step (beside wiping device)?
Have you tried using btrfs restore to see if you can restore a copy of the data e.g. onto a USB disk?
Thx for you concern Mdgm.
Yes btrfs restore works, and the volume is actually mounted (read-only) by readynas OS anyway.
So accessing the data is not looking too hard.
I just hoped to save the snapshots and avoid rebuilding and back and forth of data (6TB out and back in).
As I type this, the NAS has become unresponsive remotly, so I'll go on-site have a look and probably cold reboot. It seems Frontview is bringing it down trying to access some info (in my case Backup jobs definition).
