Readynas Ultra 6 freezes
I have a problem with my Ultra 6.
(Work on Readynas OS 6)
When I defrag my data the nas freeze.
I tried everything:
- Test disk -> Ok (smart ok for all disk)
- Scrub -> Ok
- Balance -> Ok
I tried a higher balance in ssh with btrfs balance start /data and the nas a freeze.
Ideas ??
(A/V disable on the Nas, no addons installed, the Nas is clean)

What does the top of your btrfs.log look like (the part of the log above === subvolume /data ===)

The linux command shell also froze? This sounds like a btrfs issue. Is your backup up to date?
Did you look in the system logs for btrfs errors?
You could try running the balance manually on each share, and try to isolate it.

I look in the logs, but do not see anything bad.
Maybe enter journalctl | grep -i btrfs and look in that output for file system errors. Also look at the smart stats for any signs of disk issues.
This problem is likely happening in one share. You can run your manual balance on individual shares (because each share is a btrfs subvolume). So if you aren't seeing btrfs errors or any SMART issues, that might be the next step.
