Hi all, The FAQ has a couple of sections on encryption (general and dm-crypt)
One thing that isn't explained there: if you create multiple encrypted volumes (e.g. using dm-crypt) and use Btrfs to combine them into RAID1, how does error recovery work when a read operation returns corrupted data? Without encryption, reading from one disk would give a checksum mismatch and Btrfs would read from the other disk to (hopefully) get a good copy of the data. With this encryption scenario, the failure would potentially be detected in the decryption layer code and instead of returning bad data to Btrfs, it would return some error code. In that case, will Btrfs attempt to read from the other volume and allow the application to proceed as if nothing was wrong?
