Data scrubbing on BTFRS seems to only be supported on RAID and not TRAID, can we get it added please?

Btrfs scrub also supports TRAID. You can run the following commands in the terminal:

Thanks I have done this, but btrfs has identified 15 errors. TOS6 does not report any of the errors, I can see them in the logs, but btrfs cannot repair them and TRAID cannot due to how the system is layered. How can a TRAID setup fix identified errors where there seems to be restriction by design? Thanks - ps i found the errors using `dmesg | grep -iE 'error|bad|failed|btrfs|md'`

For your situation:

First, try running Scrub: `btrfs scrub start -B /Volume1`, and see if it can automatically fix the 15 errors.

If Scrub reports "Unable to fix" or "Not fixed," then you need to try the method in the link to repair the file system: viewtopic.php?f=75&t=2575

The data cleanup function of the Btrfs file system in TOS 7 adds support for TRAID arrays in addition to conventional RAID arrays.

so are we saying there is not support for data cleanup in Btrfs in TOS 6, as thats a pretty big deal for me and data protection.

This feature may still have some limitations or issues in TOS 6. In TOS 7, we have further optimized and enhanced the related functionality. In addition to traditional RAID arrays, TOS 7 also adds support for data scrubbing on TRAID arrays, allowing the system to perform data consistency checks in a wider range of storage scenarios and further improve data protection capabilities.

Therefore, we recommend upgrading to TOS 7 to benefit from these improvements and achieve a better overall user experience.
