Hi.

I have executed the test that you have requested.

At this point I'm confused and demoralized

While 40 btrfs receive, btrfs check has reported many filesystem problems.
But at the end of all the btrfs receive, btrfs check did not find filesystem problem.
My tests have confirmed that the filesystem had no problems.

I think btrfs check detect false positives (this can change a repair in a destruction).


Regards.

Gdb
