Error Logs

While looking at the error logs it says

2019-05-01 23:01:10: BTRFS: error (device md127) in btrfs_run_delayed_refs:2995: errno=-22 unknown
2019-05-01 23:01:09: BTRFS: error (device md127) in __btrfs_free_extent:7062: errno=-22 unknown
2019-04-01 23:00:49: BTRFS: error (device md127) in __btrfs_free_extent:7062: errno=-22 unknown

Should I be worried?, it seems to appear when I run a Balance on a monthly basis.

I'd say yes.  But I don't know how to fix it (short of destroying the volume and rebuilding it from backup).

Have you checked the disk health?

Hi @claytonb

If there are BTRFS errors it would be best to Backup data to be sure and contact Support if you have a contract or you may want to purchase a contract so it can be addressed properly and just like @StephenB mentioned, it would be advisable to check on the disk health.

I have backed up data and replaced with 4x10TB drives as my current 4x4TB were reaching 20% free space, so have done a factory reset on the new drives and will copy everything back, should take about 5 days
