As long as you create your data and metadata with a mirror policy, you can
use btrfs scrubbing to find and correct broken data blocks. I think latest

It works by finding a mirrored block with correct checksum if the block in

Hello btrfs...
I tried to delete a subvolume which probably has some transid errors. After
this, the subvolume is gone but I cannot reboot - it hangs. After reisub,
the deleted subvolume is right back there (this is different from previous

Recently I upgraded to 3.2.0-rc4 due to instabilities with my btrfs
filesystem in 3.1.1. While with 3.1.1 my system completely froze, with
