RN214 on 6.10.2: The volume data encountered an error and was made read-only.
This past weekend, my ReadyNAS gave the following error: The volume data encountered an error and was made read-only. It is recommended to backup your data. There's no indication what the actual...
Those BTRFS errors might be able to fixed on the backend but it would be best if you start over. Cause of this errors might be due to dirty reboots that caused transactions to not complete. Not really sure how to explain but if you have any chances of outages or power loss or disk failures while in use then that can contribute.

OK, now we're getting somewhere.... found this in dmesg.log:

I have a UPS configured and in use, so power outages shouldn't be a cause / issue. I have backups, I'll just make sure they are good before I do a Factory Reset and restore my data.
My main concern will be my RNXtras apps, but hopefully that'll be easy to remedy.
If you've lost the installation file for your RNXtras apps, you can always log into your account there and re-download. Depending on the app, there might even be a free update.
I have the installers - I went through moving NAS devices a while back, and learned from that experience to keep everything needed for a Move / Restore on a share on the NAS, and make sure that Share is backed up. So all my scripts, apps, the ReadyNAS config, etc. are safe. :-)
I went ahead and did the reset, and ran a restore overnight using a pre-created script. So far, so good. At this point, it's just a matter of restoring a few settings that weren't kept on the /data partition. Everything else is in place.
I'd still like to know why the file system borked, if possible, but realize that not may be able to be determined from the logs. It is what it is, I have backups for this very reason, and I'm just glad it wasn't hardware related and a $ cost to replace in addition to the time & labor.
