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!
- Firmware was updated to 6.7.5
- SMB Shares set up, was working fine for almost a year, suddenly this issue.
- Was on Active Directory, I took it off AD for troubleshooting.
- When it was on Active Directory, it was suddenly read only access regardless of actual permissions setup.
- Permission changing was not possible at all (Error Code 1002030001 Commit Failed)
- Creating new share is not possible (Always with error 1013050001 "Please verify that the share name is valid and unique")
- Reset permissions function is not working ("Failed to change permission and ownership of the share -sharename-")
- Rebooting has no effect.
Please advise, this thing holds our backups and we can't continue to run our backups.

Check system logs, filesystem bterfs has errors, then forced readonly,

Could do you please create a support case through MyNETGEAR?

- Is my data safe? Can I do like check disk on btrfs?
Also do I have to pay $500 for support from netgear in this case? (My 90 day expired)
Thanks - 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?

The hard drives are Hitachi Deskstar NAS HDN724040ALE640, 4TB x12 (using Netgear's X-RAID single 36TB volume). The L3 staff keep saying it is a regular desktop drive, do not use regular desktop drive, etc.
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.
